Baseball is a bat-and-ball sport played between two teams of nine players each, taking turns batting and fielding. The game occurs over 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 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 the defensive team is to prevent batters from becoming runners, and to prevent runners' advance around the bases. A run is scored when a runner legally advances around the bases in order and touches home plate.
In baseball, a home run is scored when the ball is hit in such a way that the batter is able to circle the bases and reach home plate safely in one play without any errors being committed by the defensive team. A home run is usually achieved by hitting the ball over the outfield fence between the foul poles without the ball touching the field.
Softball is a sport similar to baseball, and it is played with a larger ball on a smaller field and with only underhand pitches permitted. Softball is played competitively at club levels, the college level, and the professional level. The game was first created in 1887 in Chicago by George Hancock.
Catcher is a position in baseball and softball. When a batter takes their turn to hit, the catcher crouches behind home plate, in front of the (home) umpire, and receives the ball from the pitcher. In addition to this primary duty, the catcher is also called upon to master many other skills in order to field the position well. The role of the catcher is similar to that of the wicket-keeper in cricket.
Tropicana Field is a multi-purpose domed stadium located in St. Petersburg, Florida, United States. The stadium has been the ballpark of the Tampa Bay Rays of Major League Baseball (MLB) since the team's inaugural season in 1998. The stadium is also used for college football, and from December 2008 to December 2017 was the home of the St. Petersburg Bowl, an annual postseason bowl game. The venue is the only non-retractable domed stadium in Major League Baseball, making it the only year-round indoor venue in MLB. Tropicana Field is the smallest MLB stadium by seating capacity when obstructed-view rows in the uppermost sections are covered with tarps as they are for most Rays games.
In baseball, the bullpen is the area where relief pitchers warm up before entering a game. A team's roster of relief pitchers is also metonymically referred to as "the bullpen". These pitchers usually wait in the bullpen if they have not yet played in a game, rather than in the dugout with the rest of the team. The starting pitcher also makes their final pregame warm-up throws in the bullpen. Managers can call coaches in the bullpen on an in-house telephone from the dugout to tell a certain pitcher to begin their warm-up tosses.
The infield fly rule is a rule of baseball and softball that treats certain fly balls as though caught, before the ball is caught, even if the infielder fails to catch it or drops it on purpose. The umpire's declaration of an infield fly means that the batter is out regardless of whether the ball is caught. The rule exists solely to prevent the defense from executing a double play or triple play by deliberately failing to catch a ball that an infielder could catch with ordinary effort.
A first baseman, abbreviated 1B, is the player on a baseball or softball team who fields the area nearest first base, the first of four bases a baserunner must touch in succession to score a run. The first baseman is responsible for the majority of plays made at that base. In the numbering system used to record defensive plays, the first baseman is assigned the number 3.
In baseball, a foul ball is a batted ball that:
Throughout the history of baseball, the rules have frequently changed as the game continues to evolve. A few common rules most professional leagues have in common is that four balls is a base on balls, three strikes is a strikeout, and three outs end a half-inning.
A baseball field, also called a ball field or baseball diamond, is the field upon which the game of baseball is played. The term can also be used as a metonym for a baseball park. The term sandlot is sometimes used, although this usually refers to less organized venues for activities like sandlot ball.
In baseball, interference occurs in situations in which a person illegally changes the course of play from what is expected. Interference might be committed by players on the offense, players not currently in the game, catchers, umpires, or spectators. Each type of interference is covered differently by the rules.
In the sports of baseball and softball, a batted ball is a pitch that has been contacted by the batter's bat. Batted balls are either fair or foul, and can be characterized as a fly ball, pop-up, line drive, or ground ball. In baseball, a foul ball counts as a strike against the batter, unless there are already two strikes on the batter, with special rules applying to foul tips and foul bunts. Fly balls are those hit in an arcing manner, with pop-ups being a subset of foul balls that do not travel far. Line drives are batted balls hit on a straight line trajectory, while ground balls are hit at a low trajectory, contact the ground shortly after being hit, and then either roll or bounce. Batted balls, especially line drives, can present a hazard to players, umpires, and spectators, as people have been seriously injured or killed after being struck by batted balls.
Ground rules are rules applying to the field, objects on and near it, and special situations relating to them, in the game of baseball. Major League Baseball has defined a set of "universal ground rules" that apply to all MLB ballparks; individual ballparks have the latitude to set ground rules above and beyond the universal ground rules, as long as they do not directly contradict each other. Additionally, a set of universal ground rules exists for the six MLB stadiums with retractable roofs, with the individual ballparks able to set additional rules.
A bench-clearing brawl is a form of fighting that occurs in sports, most notably baseball and ice hockey, in which most or all players on both teams leave their dugouts, bullpens, or benches, and charge onto the playing area in order to fight one another or try to break up a fight. Penalties for leaving the bench can range from nothing to severe.
Bat-and-ball games are field games played by two opposing teams. Action starts when the defending team throws a ball at a dedicated player of the attacking team, who tries to hit it with a bat and run between various safe areas in the field to score runs (points). The defending team can use the ball in various ways against the attacking team's players to force them off the field when they are not in safe zones, and thus prevent them from further scoring. The best known modern bat-and-ball games are cricket and baseball, with common roots in the 18th-century games played in England.
This is an alphabetical list of selected unofficial and specialized terms, phrases, and other jargon used in baseball, along with their definitions, including illustrative examples for many entries.
In baseball, a number of coaches assist in the smooth functioning of a team. They are assistants to the manager, who determines the starting lineup and batting order, decides how to substitute players during the game, and makes strategy decisions. Beyond the manager, more than a half dozen coaches may assist the manager in running the team. Essentially, baseball coaches are analogous to assistant coaches in other sports, as the baseball manager is to the head coach.
In sports, out of bounds refers to being outside the playing boundaries of the field. The legality of going out of bounds, and the ease of prevention, vary by sport. Sports that use this term include American football, Canadian football, field lacrosse, basketball, rugby union, rugby league, and association football.
Major League Baseball (MLB) uses instant replay review to allow league officials to review certain types of plays in order to determine the accuracy of the initial call of the umpires on the field. Reviews may be initiated either by a team's manager with limitations or by the umpires themselves. All instant replay reviews are examined by umpires at the Replay Command Center in New York City, who have the final decision as to whether to uphold or overturn the initial call.
