170-421: In baseball , the pitcher is the player who throws ("pitches") the baseball from the pitcher's mound toward the catcher to begin each play, with the goal of retiring a batter , who attempts to either make contact with the pitched ball or draw a walk . In the numbering system used to record defensive plays, the pitcher is assigned the number 1. The pitcher is often considered the most important player on
340-408: A ball when no part of the ball passes through the strike zone. A check swing is when the batter begins to swing, but then stops the swing short. If the batter successfully checks the swing and the pitch is out of the strike zone, it is called a ball. There are two legal pitching positions , the windup and the set position or stretch . Either position may be used at any time; typically, the windup
510-407: A closer who generally pitches the ninth inning, a setup pitcher who generally pitches the eighth, and a left-handed specialist whose job is to retire left-handed batters. The rest of the bullpen then consists of middle relievers who are used in the remaining situations, and perhaps additional left-handed or right-handed specialists. The closer is usually the best relief pitcher, followed by
680-425: A sacrifice fly . In order to increase the chance of advancing a batter to first base via a walk, the manager will sometimes signal a batter who is ahead in the count (i.e., has more balls than strikes) to take , or not swing at, the next pitch. The batter's potential reward of reaching base (via a walk) exceeds the disadvantage if the next pitch is a strike. The evolution of baseball from older bat-and-ball games
850-480: A speed over 100 miles per hour (160 km/h; 150 ft/s), ex., Aroldis Chapman . Other common types of pitches are the curveball , slider , changeup , cutter , sinker , screwball , forkball , split-fingered fastball , slurve , knuckleball , and vulcan . These generally are intended to have unusual movement or to deceive the batter as to the rotation or velocity of the ball, making it more difficult to hit. Few pitchers throw all these pitches, but most use
1020-405: A third baseman to the right of third base. The basic outfield positions are left fielder , center fielder , and right fielder . With the exception of the catcher, all fielders are required to be in fair territory when the pitch is delivered. A neutral umpire sets up behind the catcher. Other umpires will be distributed around the field as well. Play starts with a member of the batting team,
1190-451: A "super bullpen", nonetheless this is no guarantee of success since the performance of relief pitchers has been shown to fluctuate much more wildly than starting pitchers. For instance the 2016 and 2017 Cleveland Indians had the strongest bullpen in the league, however their bullpen in 2018 struggled and the Indians won their division thanks to the strength of their starting rotation. Similarly
1360-528: A 16–1 loss against the Boston Red Sox in the 2018 American League Division Series . The only regulation game in which both pitchers of record were position players occurred on May 6, 2012, when the Baltimore Orioles' designated hitter Chris Davis was the winner in a 16-inning game against Boston while Red Sox outfielder Darnell McDonald took the loss. The pitcher's duty does not cease after he pitches
1530-535: A 2.66 ERA . Mike Marshall in 1974 was the first reliever to win the Cy Young Award after a record 106 games, 15–12 record, 21 saves, and 208 innings pitched . In 1992, Eckersley was the first modern closer (first player to be used almost exclusively in ninth inning situations) to win the Cy Young, and since then only one other relief pitcher has won the Cy Young, Éric Gagné in 2003 (also
1700-447: A ball that results in the team's third out, even if it is recorded against a teammate. On rare occasions, a batter may be at the plate when, without the batter's hitting the ball, a third out is recorded against a teammate—for instance, a runner getting caught stealing (tagged out attempting to steal a base). A batter with this sort of incomplete plate appearance starts off the team's next turn batting; any balls or strikes recorded against
1870-439: A barbell. The emphasis on the workout should be on the legs and the core. Other body parts should be worked on but using lighter weights. Over lifting muscles, especially while throwing usually ends up in a strain muscle or possibly a tear. Other than the catcher, pitchers and other fielders wear very few pieces of equipment. In general the ball cap, baseball glove and cleats are equipment used. Pitchers may also keep with them at
SECTION 10
#17328479456982040-402: A base that a teammate is forced to advance to. If a ball hit into play rolls foul before passing through the infield, it becomes dead and any runners must return to the base they occupied when the play began. If the ball is hit in the air and caught before it lands, the batter has flied out and any runners on base may attempt to advance only if they tag up (contact the base they occupied when
2210-522: A catcher for their team. The pitcher catcher combination results in many throws and may increase the risk of injury. 8) If a pitcher complains of pain in their elbow, get an evaluation from a sports medicine physician. 9) Inspire youth to have fun playing baseball and other sports. Participation and enjoyment of various activities will increase the youth's athleticism and interest in sports. To counteract shoulder and elbow injury, coaches and trainers have begun utilizing "jobe" exercises, named for Frank Jobe ,
2380-432: A defensive play. At that point, the pitcher has several standard roles. The pitcher must attempt to field any balls coming up the middle, and in fact a Gold Glove Award is reserved for the pitcher with the best fielding ability. He must head over to first base , to be available to cover it, on balls hit to the right side, since the first baseman might be fielding them too far to the baseman's right to reach first base before
2550-511: A following in much of the world was a factor, more important was MLB's reluctance to allow its players to participate during the major league season. MLB initiated the World Baseball Classic , scheduled to precede its season, partly as a replacement, high-profile international tournament. The inaugural Classic , held in March 2006, was the first tournament involving national teams to feature
2720-416: A football or soccer field does not affect play the way foul territory in baseball does, so variations in that regard are largely insignificant. These physical variations create a distinctive set of playing conditions at each ballpark. Other local factors, such as altitude and climate, can also significantly affect play. A given stadium may acquire a reputation as a pitcher's park or a hitter's park, if one or
2890-567: A forfeit (the latter typically only happens in extra-inning games). Cliff Pennington of the Toronto Blue Jays , who pitched 1 ⁄ 3 of an inning in game 4 of the 2015 American League Championship Series en route to a 14–2 loss, was the only documented position player to pitch during the postseason , until Austin Romine of the New York Yankees pitched the ninth inning of Game 3 in
3060-402: A game is centered on the pitcher for the defensive team. A pitcher's particular style, time taken between pitches, and skill heavily influence the dynamics of the game and can often determine the victor. Starting with the pivot foot on the pitcher's rubber at the center of the pitcher's mound, which is 60 feet 6 inches (18.44 m) from home plate , the pitcher throws the baseball to
3230-435: A game, involves an individual, one-on-one contest: "the pitcher and the batter in a battle of wits". Pitcher, batter, and fielder all act essentially independent of each other. While coaching staffs can signal pitcher or batter to pursue certain tactics, the execution of the play itself is a series of solitary acts. If the batter hits a line drive, the outfielder is solely responsible for deciding to try to catch it or play it on
3400-421: A home run at another. A team that plays in a park with a relatively short right field, such as the New York Yankees , will tend to stock its roster with left-handed pull hitters , who can best exploit it. On the individual level, a player who spends most of his career with a team that plays in a hitter's park will gain an advantage in batting statistics over time—even more so if his talents are especially suited to
3570-495: A lead , the pitcher may attempt a pickoff , a quick throw to a fielder covering the base to keep the runner's lead in check or, optimally, effect a tag out. Pickoff attempts, however, are subject to rules that severely restrict the pitcher's movements before and during the pickoff attempt. Violation of any one of these rules could result in the umpire calling a balk against the pitcher, which permits any runners on base to advance one base with impunity. If an attempted stolen base
SECTION 20
#17328479456983740-478: A new rule officially banning the spitball and other pitches that depended on the ball being treated or roughed-up with foreign substances, resulted in a ball that traveled farther when hit. The rise of the legendary player Babe Ruth , the first great power hitter of the new era, helped permanently alter the nature of the game. In the late 1920s and early 1930s, St. Louis Cardinals general manager Branch Rickey invested in several minor league clubs and developed
3910-660: A number of competitions between clubs from different countries. Other competitions between national teams, such as the Baseball World Cup and the Olympic baseball tournament , were administered by the International Baseball Federation (IBAF) from its formation in 1938 until its 2013 merger with the International Softball Federation to create the current joint governing body for both sports,
4080-408: A park with little space between the foul lines and the stands, but a foulout in a park with more expansive foul ground. A fence in foul territory that is close to the outfield line will tend to direct balls that strike it back toward the fielders, while one that is farther away may actually prompt more collisions, as outfielders run full speed to field balls deep in the corner. These variations can make
4250-539: A permanent fixture of the post-season. Regular-season interleague play was introduced in 1997 and the second-highest attendance mark for a full season was set. In 2000, the National and American Leagues were dissolved as legal entities. While their identities were maintained for scheduling purposes (and the designated hitter distinction), the regulations and other functions—such as player discipline and umpire supervision—they had administered separately were consolidated under
4420-404: A pitcher is left-handed or right-handed, respectively. In Major League Baseball , baseball rubbing mud is used to condition game balls before pitchers use them. A skilled pitcher often throws various pitches to prevent the batter from hitting the ball well. The most basic pitch is a fastball , where the pitcher throws the ball as hard as possible. Some pitchers are able to throw a fastball at
4590-435: A pitcher who is normally a reliever that starts the game for an inning or two before yielding to someone who would normally be a starter. Sometimes the manager replaces an opener with a series of other relievers who would only pitch one or two innings in a game, usually due to injury or fatigue affecting the team's starters or other strategical reasons; this approach became known as a bullpen game . One advantage of this approach
4760-427: A pitcher's park when the strong winds off Lake Michigan are blowing in, it becomes more of a hitter's park when they are blowing out. The absence of a standardized field affects not only how particular games play out, but the nature of team rosters and players' statistical records. For example, hitting a fly ball 330 feet (100 m) into right field might result in an easy catch on the warning track at one park, and
4930-411: A player has been removed for a substitute, that player may not reenter the game. Children's games often have more lenient rules, such as Little League rules, which allow players to be substituted back into the same game. If the designated hitter (DH) rule is in effect, each team has a tenth player whose sole responsibility is to bat (and run). The DH takes the place of another player—almost invariably
5100-521: A position role to the pitcher's box in this way were often called "change" pitchers. This strategy of switching players between the mound and the outfield is still occasionally employed in modern baseball, sometimes in long extra inning games where a team is running out of players. In 1889, the first bullpen appearance occurred after rules were changed to allow a player substitution at any time. Early relief pitchers were normally starting pitchers pitching one or two innings in between starts. In 1903, during
5270-466: A result of a pinch hitter being used in the late innings of a game, especially if the pitcher is in the batting lineup due to not having the designated hitter. A reliever would then come out of the bullpen to pitch the next inning. When making a pitching change a manager will come out to the mound. He will then call in a pitcher by the tap of the arm which the next pitcher throws with. The manager or pitching coach may also come out to discuss strategy with

5440-470: A result, the pitcher who starts a game often will not be the one who finishes it, and he may not be recovered enough to pitch again for a few days. The act of throwing a baseball at high speed is very unnatural to the body and somewhat damaging to human muscles; thus pitchers are very susceptible to injuries, soreness, and general pain. Baseball teams use two strategies to address this problem: rotation and specialization. To accommodate playing nearly every day,
5610-421: A season without starting a game was Scott Proctor in 2006. From the mid-2010s onward, MLB teams have given relievers an increasing number of innings at the expense of starters, due to the baseball game moving towards higher variance, and a flexible bullpen does give the manager more options of defending against high risk offensive strategies. In response, some teams have allocated funds and made trades to create
5780-414: A series clincher"). However, the 2018 Boston Red Sox under Alex Cora managed their pitching rotation such that a starter was readily available in the bullpen every playoff game. Regarded as an "almost universal truth in baseball", "almost every starting pitcher would be better in relief". However, a starter may not necessarily be best used as a "fireman" (to stop a rally) since "the conventional wisdom
5950-619: A set-up man, Ted Power , in order to keep the Cincinnati Reds from employing their successful platoon (Power pitched 2 + 1 ⁄ 3 innings prior to giving way to lefty starter Zane Smith in the third inning) and the strategy worked in holding the Reds to only two runs; to deceive his opponents Leyland had announced the Game 6 starter at a press conference so that the Reds would set their batting order around Smith. Between their scheduled starts in
6120-441: A significant effect on how ground balls behave and are fielded as well as on baserunning. Similarly, the presence of a roof (seven major league teams play in stadiums with permanent or retractable roofs) can greatly affect how fly balls are played. While football and soccer players deal with similar variations of field surface and stadium covering, the size and shape of their fields are much more standardized. The area out-of-bounds on
6290-629: A significant number of MLB participants. The Baseball World Cup was discontinued after its 2011 edition in favor of an expanded World Baseball Classic. Baseball has certain attributes that set it apart from the other popular team sports in the countries where it has a following. All of these sports use a clock, play is less individual, and the variation between playing fields is not as substantial or important. The comparison between cricket and baseball demonstrates that many of baseball's distinctive elements are shared in various ways with its cousin sports. In clock-limited sports, games often end with
6460-457: A single game that they must rest several days before pitching in another, relief pitchers are expected to be more flexible and typically pitch in more games with a shorter time period between pitching appearances but with fewer innings pitched per appearance. A team's staff of relievers is normally referred to metonymically as a team's bullpen , which refers to the area where the relievers sit during games, and where they warm-up prior to entering
6630-409: A skillful contact hitter , the runner takes off with the pitch, drawing the shortstop or second baseman over to second base, creating a gap in the infield for the batter to poke the ball through. The sacrifice bunt , calls for the batter to focus on making soft contact with the ball, so that it rolls a short distance into the infield, allowing the runner to advance into scoring position as the batter
6800-423: A subset or blend of the basic types. Some pitchers release pitches from different arm angles, making it harder for the batter to pick up the ball's flight. (See List of baseball pitches .) A pitcher throwing well on a particular day is said to have brought his "good stuff." Pitchers use several distinct throwing styles. The most common style is a three-quarters delivery in which the pitcher's arm snaps downward with
6970-422: A team that holds the lead killing the clock rather than competing aggressively against the opposing team. In contrast, baseball has no clock, thus a team cannot win without getting the last batter out and rallies are not constrained by time. At almost any turn in any baseball game, the most advantageous strategy is some form of aggressive strategy. Whereas, in the case of multi-day Test and first-class cricket ,
Pitcher - Misplaced Pages Continue
7140-417: A team will include a group of pitchers who start games and rotate between them, allowing each pitcher to rest for a few days between starts. A team's roster of starting pitchers are usually not even in terms of skill. Exceptional pitchers are highly sought after and in the professional ranks draw large salaries, thus teams can seldom stock each slot in the rotation with top-quality pitchers. The best starter in
7310-744: A young age, a practice that has been criticized by many coaches and doctors, with some citing an increase in Tommy John surgeries in recent years. Fleisig lists nine recommendations for preventative care of children's arms. 1) Watch and respond to signs of fatigue. 2) Youth pitchers should not pitch competitively in more than 8 months in any 12-month period. 3) Follow limits for pitch counts and days of rest. 4) Youth pitchers should avoid pitching on multiple teams with overlapping seasons. 5) Youth pitchers should learn good throwing mechanics as soon as possible: basic throwing, fastball pitching and change-up pitching. 6) Avoid using radar guns. 7) A pitcher should not also be
7480-413: Is a home run : the batter and any runners on base may all freely circle the bases, each scoring a run. This is the most desirable result for the batter. The ultimate and most desirable result possible for a batter would be to hit a home run while all three bases are occupied or "loaded", thus scoring four runs on a single hit. This is called a grand slam . A player who reaches base due to a fielding mistake
7650-457: Is a throw from the outfield to third base, he has to back up the play to third base as well. The physical act of overhand pitching is complex and unnatural to the human anatomy. Most major league pitchers throw at speeds of 70 to 100 mph (110 to 160 km/h), putting high amounts of stress on the pitching arm. Pitchers are by far the most frequently injured players and many professional pitchers will have multiple surgeries to repair damage in
7820-853: Is also the increased risk of injury, such as Jose Canseco who suffered a season-ending arm injury after pitching two innings in a 1993 game. For these reasons, managers will typically only use a position player as a pitcher in a blowout loss, or in order to avoid a forfeit once they have run out of available pitchers. Typically, the position player also pitched at the high school or collegiate level, as smaller roster sizes at amateur levels forced some position players to pitch, with some were recruited in college also as pitchers, as starters or relievers. Mitch Moreland ( Mississippi State ), Ryan Rua ( Lake Erie College ), and J. D. Davis , ( Cal State Fullerton ) all played as both position players and pitchers in their collegiate careers, with Rua and Davis both being closers for their college teams. Cliff Pennington became
7990-402: Is anticipated, the catcher may call for a pitchout , a ball thrown deliberately off the plate, allowing the catcher to catch it while standing and throw quickly to a base. Facing a batter with a strong tendency to hit to one side of the field, the fielding team may employ a shift , with most or all of the fielders moving to the left or right of their usual positions. With a runner on third base,
8160-441: Is awarded a base on balls or walk, a free advance to first base. (A batter may also freely advance to first base if the batter's body or uniform is struck by a pitch outside the strike zone, provided the batter does not swing and attempts to avoid being hit.) Crucial to determining balls and strikes is the umpire's judgment as to whether a pitch has passed through the strike zone , a conceptual area above home plate extending from
8330-414: Is called. While the team at bat is trying to score runs, the team in the field is attempting to record outs. In addition to the strikeout and flyout, common ways a member of the batting team may be put out include the ground out , force out , and tag out . These occur either when a runner is forced to advance to a base, and a fielder with possession of the ball reaches that base before the runner does, or
8500-732: Is determined by playoffs that culminate in the World Series . The top level of play is similarly split in Japan between the Central and Pacific Leagues and in Cuba between the West League and East League . The World Baseball Classic , organized by the World Baseball Softball Confederation , is the major international competition of the sport and attracts the top national teams from around
8670-558: Is difficult to trace with precision. Consensus once held that today's baseball is a North American development from the older game rounders , popular among children in Great Britain and Ireland . American baseball historian David Block suggests that the game originated in England ; recently uncovered historical evidence supports this position. Block argues that rounders and early baseball were actually regional variants of each other, and that
SECTION 50
#17328479456988840-422: Is not credited with a hit—instead, the responsible fielder is charged with an error . Any runners already on base may attempt to advance on batted balls that land, or contact the ground, in fair territory, before or after the ball lands. A runner on first base must attempt to advance if a ball lands in play, as only one runner may occupy a base at any given time; the same applies for other runners if they are on
9010-405: Is rare as these players are not truly trained as pitchers and risk injury. (For instance, in a 1993 game, Jose Canseco suffered a season ending arm injury after pitching 2 innings.) Plus, they tend to throw with less velocity and skill. For these reasons, managers will typically only use a position player as a pitcher in a blowout loss, or if they have run out of available pitchers in order to avoid
9180-537: Is that it’s unwise to bring a starter in for a relief appearance with men already on base; starting pitchers take longer to warm up than relievers and tend to be most comfortable when coming in at the start of an inning with the bases empty". A good example of starters in relief was in the deciding Game 6 of the 2010 NLCS , where the San Francisco Giants bullpen utilized two starters as well as three regular relievers to get seven scoreless innings. In Game 6 of
9350-468: Is that the opener, who is often a hard-throwing specialist, can be called in to face the most dangerous hitters, who are usually near the top of the batting order, the first time they come to bat. Although the opener has only been formally regarded as a relief role in 2018, managers have sporadically used a reliever before a starter. A good example is Game 6 of the 1990 National League Championship Series when Pittsburgh Pirates manager Jim Leyland started
9520-474: Is thrown out at first. A batter, particularly one who is a fast runner, may also attempt to bunt for a hit. A sacrifice bunt employed with a runner on third base, aimed at bringing that runner home, is known as a squeeze play . With a runner on third and fewer than two outs, a batter may instead concentrate on hitting a fly ball that, even if it is caught, will be deep enough to allow the runner to tag up and score—a successful batter, in this case, gets credit for
9690-411: Is typically demarcated by a raised fence, which may be of any material and height. The fair territory between home plate and the outfield boundary is baseball's field of play, though significant events can take place in foul territory, as well. There are three basic tools of baseball: the ball , the bat , and the glove or mitt : Protective helmets are also standard equipment for all batters. At

A balk can be called on a pitcher from either position. A power pitcher is one who relies on the velocity of his pitches to succeed. Generally, power pitchers record a high percentage of strikeouts . A control pitcher succeeds by throwing accurate pitches and thus records few walks. Nearly all action during
10030-407: The 2010 ALCS , manager Joe Girardi was criticized for "managing by formula" in not calling upon ace CC Sabathia and instead going to reliever David Robertson who surrendered several runs that put the game out of reach for the New York Yankees . Starter Madison Bumgarner recorded the longest save in World Series history, pitching five scoreless innings of relief in a Game 7 3–2 victory of
10200-467: The 2014 edition . In the 2018 World Series , starter Nathan Eovaldi , originally slated to pitch Game 4, was inserted in relief during Game 3 which turned into an 18-inning marathon. In making World Series history, he became the first reliever to throw at least six innings after Rick Rhoden did so in 1977, while Eovaldi's 97 pitches set the record for the most by a reliever (and also 36 more pitches than Rick Porcello who had started that game). In

After being admitted to the Olympics as a medal sport beginning with the 1992 Games , baseball was dropped from the 2012 Summer Olympic Games at the 2005 International Olympic Committee meeting . It remained part of the 2008 Games . While the sport's lack of

A successful pitch is delivered in such a way that the batter either allows the pitch to pass through the strike zone , swings the bat at the ball and misses it, or hits the ball poorly (resulting in a pop fly or ground out). If the batter elects not to swing at the pitch, it is called a strike if any part of the ball passes through the strike zone and
11220-425: The catcher , who is positioned behind home plate and catches the ball. Meanwhile, a batter stands in the batter's box at one side of the plate, and attempts to bat the ball safely into fair play. The type and sequence of pitches chosen depend upon the particular situation in a game. Because pitchers and catchers must coordinate each pitch, a system of hand signals is used by the catcher to communicate choices to

This game was brought by immigrants to North America, where the modern version developed . Baseball's American origins, as well as its reputation as a source of escapism during troubled points in American history such as the American Civil War and
11560-410: The slider . Pitchers have different repertoires of pitches they are skillful at throwing. Conventionally, before each pitch, the catcher signals the pitcher what type of pitch to throw, as well as its general vertical or horizontal location. If there is disagreement on the selection, the pitcher may shake off the sign and the catcher will call for a different pitch. With a runner on base and taking

Unlike those of most sports, baseball playing fields can vary significantly in size and shape. While the dimensions of the infield are specifically regulated, the only constraint on outfield size and shape for professional teams, following

Pitching staffs on MLB teams have grown from 9 or 10 to as many as 12 or 13 pitchers, due to the increased importance of relief pitching. The staff generally consists of five starting pitchers, with the remaining pitchers assigned as relievers. A team's relief staff usually contains
12410-559: The 4th or 5th starter. Typically, the further down in the rotation a starting pitcher is, the weaker he is compared with the others on the staff. The "5th starter" is seen as the cut-off between the starting staff and the bullpen . A team may have a designated 5th starter, sometimes known as a spot starter or that role may shift cycle to cycle between members of the bullpen or Triple-A starters. Differences in rotation setup could also have tactical considerations as well, such as alternating right- or left-handed pitchers, in order to throw off

In games where a blowout is occurring, position players (non-pitchers) may be substituted in to pitch to save the bullpen for the next game. However, this is a rare occurrence as position players are not truly trained as pitchers, and tend to throw with less velocity and/or accuracy. There

The Central League in Japan does not have the rule and high-level minor league clubs connected to National League teams are not required to field a DH. In leagues that apply the designated hitter rule, a typical team has nine offensive regulars (including
12920-681: The DH), five starting pitchers, seven or eight relievers, a backup catcher, and two or three other reserve players. The manager , or head coach, oversees the team's major strategic decisions, such as establishing the starting rotation, setting the lineup, or batting order, before each game, and making substitutions during games—in particular, bringing in relief pitchers. Managers are typically assisted by two or more coaches ; they may have specialized responsibilities, such as working with players on hitting, fielding, pitching, or strength and conditioning. At most levels of organized play, two coaches are stationed on
13090-509: The Dodgers. Latin-American players, largely overlooked before, also started entering the majors in greater numbers. In 1951, two Chicago White Sox, Venezuelan-born Chico Carrasquel and black Cuban-born Minnie Miñoso , became the first Hispanic All-Stars . Integration proceeded slowly: by 1953, only six of the 16 major league teams had a black player on the roster. In 1975, the union's power—and players' salaries—began to increase greatly when
13260-694: The Gotham Club. While there are reports that the New York Knickerbockers played games in 1845, the contest long recognized as the first officially recorded baseball game in U.S. history took place on June 19, 1846, in Hoboken, New Jersey : the "New York Nine" defeated the Knickerbockers, 23–1, in four innings. With the Knickerbocker code as the basis, the rules of modern baseball continued to evolve over
13430-513: The United States and Canada was founded in 1878 in Cuba, which maintains a rich baseball tradition. The Dominican Republic held its first islandwide championship tournament in 1912. Professional baseball tournaments and leagues began to form in other countries between the world wars, including the Netherlands (formed in 1922), Australia (1934), Japan (1936), Mexico (1937), and Puerto Rico (1938). The Japanese major leagues have long been considered
13600-841: The United States. While baseball is widely played in Canada and many minor league teams have been based in the country, the American major leagues did not include a Canadian club until 1969, when the Montreal Expos joined the National League as an expansion team. In 1977, the expansion Toronto Blue Jays joined the American League. In 1847, American soldiers played what may have been the first baseball game in Mexico at Parque Los Berros in Xalapa , Veracruz . The first formal baseball league outside of
13770-473: The Year Award and The Sporting News Reliever of the Year Award are annually voted on and presented to relievers, with the former being split by league into the " Trevor Hoffman NL Reliever of the Year Award" and the " Mariano Rivera AL Reliever of the Year Award". The now defunct Rolaids Relief Man of the Year Award was determined by a statistical formula. Compared to starting pitchers, most relievers (with
13940-461: The all-time record with 106 games pitched in 1974, he threw 208.1 innings . Currently, although some relievers still do appear in a large number of games per season, the workload for each individual pitcher has been much reduced. Since 2008, Pedro Feliciano has three of the top four seasons in games pitched, with 92, 88 and 86. However, Feliciano only averaged 58 innings pitched during those seasons. The last pitcher to throw 100 or more innings in
14110-486: The average major league game has increased steadily through the years. At the turn of the 20th century, games typically took an hour and a half to play. In the 1920s, they averaged just less than two hours, which eventually ballooned to 2:38 in 1960. By 1997, the average American League game lasted 2:57 (National League games were about 10 minutes shorter—pitchers at the plate making for quicker outs than designated hitters). In 2004, Major League Baseball declared that its goal
14280-442: The ball to get batters or runners "out", which forces them out of the field of play. The pitcher can get the batter out by throwing three pitches which result in strikes , while fielders can get the batter out by catching a batted ball before it touches the ground, and can get a runner out by tagging them with the ball while the runner is not touching a base. The opposing teams switch back and forth between batting and fielding;
14450-444: The ball's release. Some pitchers use a sidearm delivery in which the arm arcs laterally to the torso. Some pitchers use a submarine style in which the pitcher's body tilts sharply downward on delivery, creating an exaggerated sidearm motion in which the pitcher's knuckles come very close to the mound. Effective pitching is vitally important in baseball. In baseball statistics , for each game, one pitcher will be credited with winning
14620-423: The ball. Unlike the other fielders, a pitcher and catcher must start every play in a designated area. The pitcher must be on the pitcher's mound , with one foot in contact with the pitcher's rubber , and the catcher must be behind home plate in the catcher's box . Once the ball is in play, however, the pitcher and catcher, like the other fielders, can respond to any part of the field necessary to make or assist in
14790-413: The baseball in a certain manner, and by throwing it at a certain speed, pitchers can cause the baseball to break to either side, or downward, as it approaches the batter, thus creating differing pitches that can be selected. Among the resulting wide variety of pitches that may be thrown, the four basic types are the fastball , the changeup (or off-speed pitch), and two breaking balls —the curveball and
14960-426: The batter hits the ball and reaches first base before an opponent retrieves the ball and touches the base, or when the pitcher persists in throwing the ball out of the batter's reach . Players on the batting team who reach first base without being called " out " can attempt to advance to subsequent bases as a runner, either immediately or during teammates' turns batting. The fielding team tries to prevent runs by using
15130-454: The batter the previous inning are erased. A runner may circle the bases only once per plate appearance and thus can score at most a single run per batting turn. Once a player has completed a plate appearance, that player may not bat again until the eight other members of the player's team have all taken their turn at bat in the batting order . The batting order is set before the game begins, and may not be altered except for substitutions . Once
15300-407: The batter, standing in either of the two batter's boxes next to home plate, holding a bat. The batter waits for the pitcher to throw a pitch (the ball) toward home plate, and attempts to hit the ball with the bat. The catcher catches pitches that the batter does not hit—as a result of either electing not to swing or failing to connect—and returns them to the pitcher. A batter who hits the ball into
15470-417: The batter-runner can. Except for the first baseman, the pitcher ordinarily has the shortest run to first base of anyone, and is the second-most-likely person to make a putout at first base by retrieving a fielded ball thrown by an infielder (typically a first baseman). On passed balls and wild pitches , he covers home-plate when there are runners on. Also, he generally backs up throws to home plate. When there
15640-464: The batting team's turn to bat is over once the fielding team records three outs. One turn batting for each team constitutes an inning . A game is usually composed of nine innings, and the team with the greater number of runs at the end of the game wins. Most games end after the ninth inning, but if scores are tied at that point, extra innings are usually played. Baseball has no game clock, though some competitions feature pace-of-play regulations such as
15810-418: The beginning of each half-inning, the nine players of the fielding team arrange themselves around the field. One of them, the pitcher , stands on the pitcher's mound. The pitcher begins the pitching delivery with one foot on the rubber, pushing off it to gain velocity when throwing toward home plate. Another fielding team player, the catcher , squats on the far side of home plate, facing the pitcher. The rest of
15980-413: The bounce and for succeeding or failing. The statistical precision of baseball is both facilitated by this isolation and reinforces it. Cricket is more similar to baseball than many other team sports in this regard: while the individual focus in cricket is mitigated by the importance of the batting partnership and the practicalities of tandem running, it is enhanced by the fact that a batsman may occupy
16150-417: The clinching Games of the 2018 NLCS and 2018 World Series , respectively, aces Clayton Kershaw (for Kenley Jansen ) and Chris Sale (for Craig Kimbrel , indeed the other pitcher warming up besides Sale was another starter, Nathan Eovaldi ) pitched the ninth-inning in lieu of their team's regular closer. Neither relief entrance was a high pressure situation as their teams were already leading 5-1 entering
16320-505: The course of several plays , with each play generally beginning when a player on the fielding team , called the pitcher , throws a ball that a player on the batting team , called the batter , tries to hit with a bat . The objective of the offensive team (batting team) is to hit the ball into the field of play, away from the other team's players, allowing its players to run the bases , having them advance counter-clockwise around four bases to score what are called " runs ". The objective of
16490-414: The defensive side of the game, and as such is situated at the right end of the defensive spectrum . There are many different types of pitchers, such as the starting pitcher , relief pitcher , middle reliever , lefty specialist , setup man , and the closer . Traditionally, the pitcher also bats. Starting in 1973 with the American League and spreading to further leagues throughout the 1980s and 1990s,
16660-425: The defensive team (referred to as the fielding team) is to prevent batters from becoming runners , and to prevent runners advancing around the bases . A run is scored when a runner legally advances around the bases in order and touches home plate (the place where the player started as a batter). The initial objective of the batting team is to have a player reach first base safely ; this generally occurs either when
16830-473: The difference between a double and a triple or inside-the-park home run . The surface of the field is also unregulated. While the adjacent image shows a traditional field surfacing arrangement (and the one used by virtually all MLB teams with naturally surfaced fields), teams are free to decide what areas will be grassed or bare. Some fields—including several in MLB—use artificial turf . Surface variations can have
17000-613: The early 1830s, there were reports of a variety of uncodified bat-and-ball games recognizable as early forms of baseball being played around North America. The first officially recorded baseball game in North America was played in Beachville, Ontario , Canada, on June 4, 1838. In 1845, Alexander Cartwright , a member of New York City's Knickerbocker Club , led the codification of the so-called Knickerbocker Rules , which in turn were based on rules developed in 1837 by William R. Wheaton of
17170-418: The effect of shortening 2023 regular season games by 24 minutes on average. Although baseball is a team sport, individual players are often placed under scrutiny and pressure. While rewarding, it has sometimes been described as "ruthless" due to the pressure on the individual player. In 1915, a baseball instructional manual pointed out that every single pitch, of which there are often more than two hundred in
17340-406: The elbow and shoulder by the end of their careers. As such, the biomechanics of pitching are closely studied and taught by coaches at all levels and are an important field in sports medicine . Glenn Fleisig, a biomechanist who specializes in the analysis of baseball movements, says that pitching is "the most violent human motion ever measured." He claims that the pelvis can rotate at 515–667°/sec,
17510-553: The except of closers with large save totals) receive few awards and honors. Historically, setup men were rarely selected to MLB All-Star Games , with the relievers selected usually being closers. A setup man has never won the Cy Young Award or the Major League Baseball Most Valuable Player Award ; the highest placements in these respective awards have been achieved by Rivera, who finished third in
17680-488: The field of play must drop the bat and begin running toward first base, at which point the player is referred to as a runner (or, until the play is over, a batter-runner ). A batter-runner who reaches first base without being put out is said to be safe and is on base. A batter-runner may choose to remain at first base or attempt to advance to second base or even beyond—however far the player believes can be reached safely. A player who reaches base despite proper play by
17850-476: The field to confer with players during a game. Any baseball game involves one or more umpires , who make rulings on the outcome of each play. At a minimum, one umpire will stand behind the catcher, to have a good view of the strike zone, and call balls and strikes. Additional umpires may be stationed near the other bases, thus making it easier to judge plays such as attempted force outs and tag outs. In MLB, four umpires are used for each game, one near each base. In
18020-467: The field when the team is at bat: the first base coach and third base coach, who occupy designated coaches' boxes, just outside the foul lines. These coaches assist in the direction of baserunners, when the ball is in play, and relay tactical signals from the manager to batters and runners, during pauses in play. In contrast to many other team sports, baseball managers and coaches generally wear their team's uniforms; coaches must be in uniform to be allowed on
18190-410: The field, returning to their team's dugout or bench. A runner may be stranded on base when a third out is recorded against another player on the team. Stranded runners do not benefit the team in its next turn at bat as every half-inning begins with the bases empty. An individual player's turn batting or plate appearance is complete when the player reaches base, hits a home run, makes an out, or hits
18360-408: The fielders has recorded a hit . A player who reaches first base safely on a hit is credited with a single . If a player makes it to second base safely as a direct result of a hit, it is a double ; third base, a triple . If the ball is hit in the air within the foul lines over the entire outfield (and outfield fence, if there is one), or if the batter-runner otherwise safely circles all the bases, it
18530-417: The fielding team faces home plate, typically arranged as four infielders—who set up along or within a few yards outside the imaginary lines (basepaths) between first, second, and third base—and three outfielders. In the standard arrangement , there is a first baseman positioned several steps to the left of first base, a second baseman to the right of second base, a shortstop to the left of second base, and
18700-687: The first British baseball champions winning the 1890 National League of Baseball of Great Britain . The 2020 National Champions were the London Mets . Other European countries have seen professional leagues; the most successful, other than the Dutch league , is the Italian league , founded in 1948. In 2004, Australia won a surprise silver medal at the Olympic Games . The Confédération Européene de Baseball (European Baseball Confederation), founded in 1953, organizes
18870-604: The first modern farm system . A new Negro National League was organized in 1933; four years later, it was joined by the Negro American League . The first elections to the National Baseball Hall of Fame took place in 1936. In 1939, Little League Baseball was founded in Pennsylvania. Many minor league teams disbanded when World War II led to a player shortage. Chicago Cubs owner Philip K. Wrigley led
19040-513: The first position player in Major League Baseball history to pitch in a postseason game, which was during Game 4 of the 2015 American League Championship Series . The second position player to pitch in the playoffs was Austin Romine during Game 3 of the 2018 American League Division Series . Starting in 2023 , MLB position players are allowed to pitch in a game under the following conditions: The Major League Baseball Reliever of
19210-581: The formation of the All-American Girls Professional Baseball League to help keep the game in the public eye. The first crack in the unwritten agreement barring blacks from white-controlled professional ball occurred in 1945: Jackie Robinson was signed by the National League's Brooklyn Dodgers and began playing for their minor league team in Montreal . In 1947, Robinson broke the major leagues' color barrier when he debuted with
19380-400: The foul lines is referred to as fair territory; the 270-degree area outside them is foul territory. The part of the field enclosed by the bases and several yards beyond them is the infield ; the area farther beyond the infield is the outfield . In the middle of the infield is a raised pitcher's mound, with a rectangular rubber plate (the rubber) at its center. The outer boundary of the outfield
19550-699: The game accompanied by Metallica 's " Enter Sandman " booming over Yankee Stadium's sound system. When Jonathan Papelbon was with the Red Sox , his entry song was the Dropkick Murphys ' " I'm Shipping Up to Boston ", and Hoffman entered to the tune of AC/DC 's " Hells Bells ". Eight pitchers are currently in the Baseball Hall of Fame chiefly for their accomplishments as relief pitchers: Goose Gossage , Hoyt Wilhelm , Rollie Fingers , Bruce Sutter , Dennis Eckersley , Lee Smith , Hoffman, and Rivera. Eckersley, who
19720-596: The game's most direct antecedents are the English games of stoolball and "tut-ball". The earliest known reference to baseball is in a 1744 British publication, A Little Pretty Pocket-Book , by John Newbery . Block discovered that the first recorded game of "Bass-Ball" took place in 1749 in Surrey , and featured the Prince of Wales as a player. This early form of the game was apparently brought to Canada by English immigrants. By
19890-421: The game, and he may be followed by various relief pitchers , such as the long reliever , the left-handed specialist , the middle reliever , the setup man , and/or the closer . In abbreviating baseball positions, P is used as a general designation for pitchers. SP and RP are sometimes used to differentiate starting and relief pitchers, respectively, while LHP and RHP are sometimes used to indicate if
20060-421: The game, and one pitcher will be charged with losing it. These are not necessarily the starting pitchers for each team; however, a reliever can win, and the starter would then get a no-decision. Pitching is physically demanding, especially if the pitcher is throwing with maximum effort. A full game usually involves 120–170 pitches thrown by each team, and most pitchers begin to tire before they reach this point. As
20230-419: The game. In the early days of Major League Baseball (MLB), substituting a player was not allowed except for sickness or injury. An ineffective pitcher would switch positions with another player on the field. The first relief appearance in the major leagues was in 1876 with Boston Red Caps outfielder Jack Manning switching positions with pitcher Joe Borden . In this early era, relief pitchers changing from
20400-490: The height of fences or other structures at the edge of the outfield. The most famously idiosyncratic outfield boundary is the left-field wall at Boston's Fenway Park , in use since 1912: the Green Monster is 310 feet (94 m) from home plate down the line and 37 feet (11 m) tall. Similarly, there are no regulations at all concerning the dimensions of foul territory. Thus a foul fly ball may be entirely out of play in
20570-481: The high school level and in doubleheaders in college, Minor League Baseball and, since the 2020 season , Major League Baseball ; and six innings at the Little League level). One team—customarily the visiting team—bats in the top, or first half, of every inning. The other team—customarily the home team—bats in the bottom, or second half, of every inning. The goal of the game is to score more points ( runs ) than
20740-821: The highest quality professional circuits outside of the United States. After World War II, professional leagues were founded in many Latin American countries, most prominently Venezuela (1946) and the Dominican Republic (1955). Since the early 1970s, the annual Caribbean Series has matched the championship clubs from the four leading Latin American winter leagues: the Dominican Professional Baseball League , Mexican Pacific League , Puerto Rican Professional Baseball League , and Venezuelan Professional Baseball League . In Asia, South Korea (1982), Taiwan (1990) and China (2003) all have professional leagues. The English football club, Aston Villa , were
20910-485: The hitting duties of the pitcher have generally been given over to the position of designated hitter , a cause of some controversy. The National League adopted the designated hitter in 2022; as of 2024, the Japanese Central League is the highest level of competition to not use the designated hitter position. In most cases, the objective of the pitcher is to deliver the pitch to the catcher without allowing
21080-667: The increase in offense. Relievers became more respected in the 1970s, and their pay increased due to free agency . All teams began having a closer . The 1980s were the first time in MLB that the number of saves outnumbered complete games . In 1995, there were nearly four saves for every complete game. It is unclear whether the specialization and reliance on relief pitchers led to pitch counts and fewer complete games, or whether pitch counts led to greater use of relievers. As closers were reduced to one-inning specialists, setup men and middle relievers became more prominent. In past decades,
21250-410: The infielders may play in , moving closer to home plate to improve the odds of throwing out the runner on a ground ball , though a sharply hit grounder is more likely to carry through a drawn-in infield. Several basic offensive tactics come into play with a runner on first base, including the fundamental choice of whether to attempt a steal of second base. The hit and run is sometimes employed, with
21420-426: The lessened exposure of their abilities became an advantage many would learn to capitalize on. Because these pitchers only faced some batters once a season, the opposing side would have greater difficulty preparing to face relief pitchers. Recently, being a relief pitcher has become more of a career, rather than a reduced position. Many of today's top prospects are considered mainly for their relief pitching skills. In
21590-406: The line may be journeymen as their individual performances may vary greatly (often specialised to pitch against certain types of batters, such as to right-handed batters only or left-handed batters only), even though their team's relief pitching staff as a whole is overall effective. The rising importance placed on relief pitchers is evident in the rising star power of the closer. It has gotten to
21760-439: The manager of the batting team trying to arrange opposite-handed matchups. With a team that has the lead in the late innings, a manager may remove a starting position player—especially one whose turn at bat is not likely to come up again—for a more skillful fielder (known as a defensive substitution ). The tactical decision that precedes almost every play in a baseball game involves pitch selection. By gripping and then releasing
21930-407: The midpoint between the batter's shoulders and belt down to the hollow of the knee. Any pitch which does not pass through the strike zone is called a ball, unless the batter either swings and misses at the pitch, or hits the pitch into foul territory; an exception generally occurs if the ball is hit into foul territory when the batter already has two strikes, in which case neither a ball nor a strike
22100-463: The mound a bag of powdered rosin . Handling the bag applies a small layer of the rosin to the pitcher's fingers in order to increase his grip on the ball. Currently there is a new trend of introducing a pitcher helmet to provide head protection from batters hitting line drives back to the pitcher. As of January 2014, MLB approved a protective pitchers cap which can be worn by any pitcher if they choose. San Diego Padres relief pitcher, Alex Torres
22270-411: The need for several days of rest between appearances. Relief pitchers are typically pitchers with "special stuff", meaning that they have very effective pitches or a very different style of delivery. This makes the batter see a very different way of pitching in attempt to get them out. One example is a sidearm or submarine pitcher. Position players are eligible to pitch in a game as well, this however
22440-503: The next half-century. The game then went on to spread throughout the Pacific Rim and the Americas, with Americans backing the sport as a way to spread American values. In the mid-1850s, a baseball craze hit the New York metropolitan area , and by 1856, local journals were referring to baseball as the "national pastime" or "national game". A year later, the sport's first governing body,
22610-536: The other discipline notably benefits from its unique mix of elements. The most exceptional park in this regard is Coors Field , home of the Colorado Rockies . Its high altitude—5,282 feet (1,610 m) above sea level—is partly responsible for giving it the strongest hitter's park effect in the major leagues due to the low air pressure. Wrigley Field , home of the Chicago Cubs, is known for its fickle disposition:
22780-408: The other team's hitting game-to-game in a series. Teams have additional pitchers reserved to replace that game's starting pitcher if he tires or proves ineffective. These players are called relief pitchers , relievers , or collectively the bullpen . Once a starter begins to tire or is starting to give up hits and runs a call is made to the bullpen to have a reliever start to warm up. This involves
22950-558: The other team. The players on the team at bat attempt to score runs by touching all four bases, in order, set at the corners of the square-shaped baseball diamond . A player bats at home plate and must attempt to safely reach a base before proceeding, counterclockwise , from first base, to second base, third base, and back home to score a run. The team in the field attempts to prevent runs from scoring by recording outs , which remove opposing players from offensive action until their next turn at bat comes up again. When three outs are recorded,
23120-636: The park. Relief pitcher In baseball and softball , a relief pitcher or reliever is a pitcher who pitches in the game after the starting pitcher or another relief pitcher has been removed from the game due to fatigue , injury, ineffectiveness, ejection , high pitch count, or for other strategic reasons, such as inclement weather delays or pinch hitter substitutions. Relief pitchers are further divided informally into various roles, such as closers , setup men , middle relief pitchers , left/right-handed specialists , and long relievers . Whereas starting pitchers usually throw so many pitches in
23290-653: The pioneer of the Tommy John procedure. Jobes are exercises that have been developed to isolate, strengthen and stabilize the rotator cuff muscles. Jobes can be done using either resistance bands or lightweight dumbbells. Common jobe exercises include shoulder external rotation, shoulder flexion, horizontal abduction, prone abduction and scaption (at 45°, 90° and inverse 45°). In addition to the Jobes exercises, many pitching coaches are creating lifting routines that are specialized for pitchers. Pitchers should avoid exercises that deal with
23460-409: The pitcher, but on his second trip to the mound with the same pitcher in the same inning, the pitcher has to come out. It is considered proper etiquette for the pitcher to wait on the mound until the manager arrives, whereby he then hands the manager the ball, and only then he is allowed to leave the field. Relief pitchers often have even more specialized roles, and the particular reliever used depends on
23630-461: The pitcher, who either vetoes or accepts by shaking his head or nodding. The relationship between pitcher and catcher is so important that some teams select the starting catcher for a particular game based on the starting pitcher. Together, the pitcher and catcher are known as the battery . Although the object and mechanics of pitching remain the same, pitchers may be classified according to their roles and effectiveness. The starting pitcher begins
23800-461: The pitcher—in the batting order, but does not field. Thus, even with the DH, each team still has a batting order of nine players and a fielding arrangement of nine players. The number of players on a baseball roster, or squad , varies by league and by the level of organized play. A Major League Baseball (MLB) team has a roster of 26 players with specific roles. A typical roster features the following players: Most baseball leagues worldwide have
23970-412: The play began, as or after the ball is caught). Runners may also attempt to advance to the next base while the pitcher is in the process of delivering the ball to home plate; a successful effort is a stolen base . A pitch that is not hit into the field of play is called either a strike or a ball. A batter against whom three strikes are recorded strikes out . A batter against whom four balls are recorded
24140-447: The playoffs, six umpires are used: one at each base and two in the outfield along the foul lines. Many of the pre-game and in-game strategic decisions in baseball revolve around a fundamental fact: in general, right-handed batters tend to be more successful against left-handed pitchers and, to an even greater degree, left-handed batters tend to be more successful against right-handed pitchers. A manager with several left-handed batters in
24310-467: The point where closers are among the biggest stars in the game, with status and salaries on par with starting pitchers. When closers play at home, and when they are called into the game to preserve a lead for the crucial last inning or those last couple of outs, many of them trot in from the bullpen to the pitchers mound accompanied by a theme song of their choice. For many years with the Yankees , Rivera entered
24480-404: The possibility of a draw (which occurs because of the restrictions on time, which like in baseball, originally did not exist ) often encourages a team that is batting last and well behind, to bat defensively and run out the clock, giving up any faint chance at a win, to avoid an overall loss. While nine innings has been the standard since the beginning of professional baseball, the duration of
24650-456: The preceding decade's average of 3:18. In 2016, the average nine-inning playoff game in Major League baseball was 3 hours and 35 minutes. This was up 10 minutes from 2015 and 21 minutes from 2014. In response to the lengthening of the game, MLB decided from the 2023 season onward to institute a pitch clock rule to penalize batters and pitchers who take too much time between pitches; this had
24820-479: The quest for a managerial edge, managers as time goes on have carried more pitchers in the bullpen, and used them in more specialized situations. Acknowledgment of the platoon edge has prompted managers to ensure that opposing lefty hitters face as many lefty pitchers as possible, and that the same occur with respect to righty hitters and pitchers. Tony La Russa was particularly well known for making frequent pitching changes on this basis. When Mike Marshall set
24990-463: The regular lineup, who knows the team will be facing a left-handed starting pitcher, may respond by starting one or more of the right-handed backups on the team's roster. During the late innings of a game, as relief pitchers and pinch hitters are brought in, the opposing managers will often go back and forth trying to create favorable matchups with their substitutions. The manager of the fielding team trying to arrange same-handed pitcher-batter matchups and
25160-463: The relief pitcher was merely an ex-starter who came into a game upon the injury, ineffectiveness, or fatigue of the starting pitcher. The bullpen was for old starters who had lost the ability to throw effectively. Many of these pitchers would be able to flourish in this diminished role. Those such as Dennis Eckersley , as with many others, actually prolonged their tapering careers and often sparked them to new life. The added rest to their arms as well as
25330-414: The reliever starting to throw practice balls to a coach in the bullpen so as to be ready to come in and pitch whenever the manager wishes to pull the current pitcher. Having a reliever warm up does not always mean he will be used; the current pitcher may regain his composure and retire the side, or the manager may choose to go with another reliever if strategy dictates. Commonly, pitching changes will occur as
25500-527: The reserve clause was effectively struck down , leading to the free agency system . Significant work stoppages occurred in 1981 and 1994 , the latter forcing the cancellation of the World Series for the first time in 90 years. Attendance had been growing steadily since the mid-1970s and in 1994, before the stoppage, the majors were setting their all-time record for per-game attendance. After play resumed in 1995, non-division-winning wild card teams became
25670-463: The rotation, a starting pitcher can be used on short rest for the bullpen. They are sometimes used as relievers when the stakes are higher, such as a game that could decide the division title or an elimination (winner-take all) playoff game. Currently, starters are typically used in relief situations either early in the postseason prior to their scheduled rotation start, or late in the postseason after their last scheduled start (often with "the ultimatum of
25840-413: The rubric of MLB. In 2001, Barry Bonds established the current record of 73 home runs in a single season. There had long been suspicions that the dramatic increase in power hitting was fueled in large part by the abuse of illegal steroids (as well as by the dilution of pitching talent due to expansion), but the issue only began attracting significant media attention in 2002 and there was no penalty for
26010-616: The rules of MLB and Minor League Baseball , is that fields built or remodeled since June 1, 1958, must have a minimum distance of 325 feet (99 m) from home plate to the fences in left and right field and 400 feet (122 m) to center. Major league teams often skirt even this rule. For example, at Minute Maid Park , which became the home of the Houston Astros in 2000, the Crawford Boxes in left field are only 315 feet (96 m) from home plate. There are no rules at all that address
26180-449: The runner is touched by the ball, held in a fielder's hand, while not on a base. (The batter-runner is always forced to advance to first base, and any other runners must advance to the next base if a teammate is forced to advance to their base.) It is possible to record two outs in the course of the same play. This is called a double play . Three outs in one play, a triple play , is possible, though rare. Players put out or retired must leave
26350-431: The second game of the inaugural World Series , Pittsburgh 's Bucky Veil became the first relief pitcher in World Series history. Firpo Marberry is credited with being the first prominent reliever. From 1923 to 1935, he pitched in 551 games , 364 of which were in relief. Baseball historian Bill James wrote that Marberry was "a modern reliever—a hard throwing young kid who worked strictly in relief, worked often, and
26520-405: The setup man. Players typically get promoted into later-inning roles as they succeed. Relievers were previously more multipurpose before becoming one-inning specialists. The setup man and closer will normally only be used to preserve a lead, although they may enter to maintain a close game (where the score is tied or if their team is trailing by only a few runs) particularly in the playoffs. If
26690-600: The situation. Many teams designate one pitcher as the closer , a relief pitcher specifically reserved to pitch the final inning or innings of a game when his team has a narrow lead, in order to preserve the victory. More recently, teams began experimenting with an opener , a relief pitcher who starts a game but only pitches at least the first inning. Other relief roles include set-up men , middle relievers , left-handed specialists , and long relievers . Generally, relievers pitch fewer innings and throw fewer pitches than starters, but they can usually pitch more frequently without
26860-528: The team is significantly behind going into the eighth or ninth inning and a relief pitcher is required, usually a middle reliever or two will be chosen to soak up innings, while the setup man and closer are saved for the next time they are needed to preserve a win. The proper use of the bullpen is to avoid using an effective reliever on a low-leverage situation, instead saving them as "fireman" for high-leverage situations (such as bases-loaded, no-outs). In 2018, some MLB teams began experimenting with an opener –
27030-434: The team's rotation is called the ace . He is usually followed in the rotation by 3 or 4 other starters before he would be due to pitch again. Barring injury or exceptional circumstances, the ace is usually the pitcher that starts on Opening Day. Aces are also preferred to start crucial games late in the season and in the playoffs; sometimes they are asked to pitch on shorter rest if the team feels he would be more effective than
27200-406: The teams switch roles for the next half-inning. If the score of the game is tied after nine innings, extra innings are played to resolve the contest. Many amateur games, particularly unorganized ones, involve different numbers of players and innings. The game is played on a field whose primary boundaries, the foul lines, extend forward from home plate at 45-degree angles. The 90-degree area within
27370-531: The time. Gradually after World War II, full-time relievers became more acceptable and standard. The relievers were usually pitchers that were not good enough to be starters. Relievers in the 1950s started to develop oddball pitches to distinguish them from starters. For example, Hoyt Wilhelm threw a knuckleball , and Elroy Face threw a forkball . In 1969, the pitcher's mound was lowered and umpires were encouraged to call fewer strikes to give batters an advantage. Relief specialists were used to counter
27540-1047: The trunk can rotate at 1,068–1,224°/s, the elbow can reach a maximal angular velocity of 2,200–2,700°/s and the force pulling the pitcher's throwing arm away from the shoulder at ball release is approximately 280 pounds-force (1,200 N ). The overhead throwing motion can be divided into phases which include windup, early cocking, late cocking, early acceleration, late acceleration, deceleration, and follow-through. Training for pitchers often includes targeting one or several of these phases. Biomechanical evaluations are sometimes done on individual pitchers to help determine points of inefficiency. Mechanical measurements that are assessed include, but are not limited to, foot position at stride foot contact (SFC), elbow flexion during arm cocking and acceleration phases, maximal external rotation during arm cocking, horizontal abduction at SFC, arm abduction, lead knee position during arm cocking, trunk tilt, peak angular velocity of throwing arm and angle of wrist. Some players begin intense mechanical training at
27710-580: The two major league champions against each other, was inaugurated that fall. The Black Sox Scandal of the 1919 World Series led to the formation of the office of the Commissioner of Baseball . The first commissioner, Kenesaw Mountain Landis , was elected in 1920. That year also saw the founding of the Negro National League ; the first significant Negro league, it would operate until 1931. For part of
27880-505: The use of performance-enhancing drugs before 2004. In 2007, Bonds became MLB's all-time home run leader, surpassing Hank Aaron , as total major league and minor league attendance both reached all-time highs. Despite having been called "America's national pastime", baseball is well-established in several other countries. As early as 1877, a professional league, the International Association , featured teams from both Canada and
28050-478: The voting for the American League (AL) Cy Young Award and twelfth for the AL MVP in 1996, and for the next season he was promoted to closer. Middle reliever Andrew Miller became the first relief pitcher other than a closer to win a League Championship Series Most Valuable Player Award when he was voted the 2016 ALCS MVP. Setup pitchers typically make less than the MLB average salary. Relief pitchers further down
28220-494: The world. Baseball was played at the Olympic Games from 1992 to 2008, and was reinstated on a one-off basis in 2020. A baseball game is played between two teams, each usually composed of nine players, that take turns playing offense (batting and baserunning) and defense (pitching and fielding). A pair of turns, one at bat and one in the field, by each team constitutes an inning . A game consists of nine innings (seven innings at
28390-529: Was an average game of 2:45. By 2014, though, the average MLB game took over three hours to complete. The lengthening of games is attributed to longer breaks between half-innings for television commercials, increased offense, more pitching changes, and a slower pace of play, with pitchers taking more time between each delivery, and batters stepping out of the box more frequently. Other leagues have experienced similar issues. In 2008, Nippon Professional Baseball took steps aimed at shortening games by 12 minutes from
28560-546: Was considered the first modern closer pitching exclusively in ninth inning situations, also had a significant career as a starting pitcher and even threw a no-hitter in 1977. Another pitcher entering the Hall in 2015 , John Smoltz , was primarily a starter, but spent four seasons as a reliever. Jim Konstanty in 1950 was the first reliever to win the MLB MVP Award after a then-record 74 games, 16–7 record , 22 saves, and
28730-530: Was the first player in MLB to wear the protective cap. One style of helmet is worn on top of the ballcap to provide protection to the forehead and sides. In softball , a full face helmet is available to all players including pitchers. These fielder's masks are becoming increasingly popular in younger fast pitch leagues, some leagues even requiring them. Baseball Baseball is a bat-and-ball sport played between two teams of nine players each, taking turns batting and fielding . The game occurs over
28900-569: Was used to nail down victories". Another reliever, Johnny Murphy , became known as "Fireman" for his effectiveness when inserted into difficult situations ("put out fires") in relief. Nonetheless, the full-time reliever who was entrusted with important situations was more the exception than the rule at this point. Often, a team's ace starting pitcher was used in between his starts to "close" games. Later research would reveal that Lefty Grove would have been in his league's top three in saves in four different seasons, had that stat been invented at
