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.
In baseball, the strike zone is the volume of space through which a pitch must pass in order to be called a strike even if the batter does not swing. The strike zone is defined as the volume of space above home plate and between the batter's knees and the midpoint of their torso. Whether a pitch passes through the zone is decided by an umpire, who is generally positioned behind the catcher.
Softball is a popular variation of baseball, the difference being that 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.
In baseball, an intentional base on balls, usually referred to as an intentional walk and denoted in baseball scorekeeping by IBB, is a walk issued to a batter by a pitcher with the intent of removing the batter's opportunity to swing at the pitched ball. A pitch that is intentionally thrown far outside the strike zone for this purpose is referred to as an intentional ball.
In baseball, a foul ball is a batted ball that:
In baseball, an out occurs when the umpire rules a batter or baserunner out. When a batter or runner is out, they lose their ability to score a run and must return to the dugout until their next turn at bat. When three outs are recorded in a half-inning, the batting team's turn expires.
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.
Baseball and cricket are the best-known members of a family of related bat-and-ball games. Both have fields that are 400 feet (120 m) or more in diameter between their furthest endpoints, offensive players who can hit a thrown/"bowled" ball out of the field and run between safe areas to score runs (points) at the risk of being gotten out, and have a major game format lasting about 3 hours.
In baseball, batting is the act of facing the opposing pitcher and trying to produce offense for one's team. A batter or hitter is a person whose turn it is to face the pitcher. The three main goals of batters are to become a baserunner, to drive runners home or to advance runners along the bases for others to drive home, but the techniques and strategies they use to do so vary. Hitting uses a motion that is virtually unique to baseball and its fellow bat-and-ball sports, one that is rarely used in other sports. Hitting is unique because it involves rotating in the horizontal plane of movement, unlike most sports movements which occur in the vertical plane.
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 fly 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.
Pesäpallo is a fast-moving bat-and-ball sport that is often referred to as the national sport of Finland and has some presence in other places including Germany, Sweden, Switzerland, Australia, and Canada's northern Ontario. It is similar to brännboll, rounders, lapta, and baseball.
In major league baseball, the dead-ball era refers to a period from about 1900 to 1920 in which run scoring was low and home runs were rare in comparison to the years that followed. In 1908, the major league batting average dropped to .239, and teams averaged just 3.4 runs per game, the lowest ever. Spacious ballparks limited hitting for power, and the ball itself was "dead" both by design and from overuse. Ball scuffing and adulteration by pitchers, particularly the spitball, were allowed, putting hitters at a disadvantage.
Dartball is a game in which darts are thrown at a large wooden or Homasote board that resembles a baseball field with colored areas which denote bases. Dartball uses baseball-like rules and scoring.
Bat-and-ball games, or safe haven 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 then 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.
