Baseball statistics refers to a variety of metrics used to evaluate player and team performance in the game of baseball.
In baseball statistics, a hit, also called a base hit, is credited to a batter when the batter safely reaches or passes first base after hitting the ball into fair territory with neither the benefit of an error nor a fielder's choice.
In baseball, a sacrifice fly is defined by Rule 9.08(d): "Score a sacrifice fly when, before two are out, the batter hits a ball in flight handled by an outfielder or an infielder running in the outfield in fair or foul territory that
- is caught, and a run scores after the catch, or
- is dropped, and a runner scores, if in the scorer's judgment the runner could have scored after the catch had the fly ball been caught."
In baseball, a stolen base occurs when a runner advances to a base unaided by other actions and the official scorer rules that the advance should be credited to the action of the runner. The umpires determine whether the runner is safe or out at the next base, but the official scorer rules on the question of credit or blame for the advance under Rule 10 of the MLB's Official Rules.
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.
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.
An infielder is a baseball player stationed at one of four defensive "infield" positions on the baseball field, between first base and third base.
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.
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.
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.
A hit and run is a high risk, high reward offensive strategy used in baseball. It uses a stolen base attempt to try to place the defending infielders out of position for an attempted base hit.
In the sport of baseball, small ball is an informal term for an offensive strategy in which the batting team emphasizes placing runners on base and then advancing them into scoring position for a run in a deliberate, methodical way. This strategy places a high value on individual runs and attempts to score them without requiring extra base hits, or sometimes without base hits at all, instead using bases on balls, stolen bases, sacrifice bunt or sacrifice fly balls, the hit-and-run play, and aggressive baserunning with such plays as the contact play. A commonly used term for a run produced playing small ball is a "manufactured run". This style of play was more often found in National League game situations than in the American League due in large part to the absence of the designated hitter in the National League until the universal adoption of the Designated Hitter.
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, base running is the act of running from base to base, performed by members of the team at bat.
A fifth infielder is the rare instance in baseball when a team may elect to bring in an outfielder to play the infield. This is usually done when the game is tied in the bottom of the ninth or an extra inning, the home team has a runner at 3rd base with fewer than two outs. Normally with a runner on 3rd with less than two outs, a manager will usually have the infield playing in, as to cut down a runner trying to score. Bringing the infield in is a typical strategy used late in games, when a potential tying, go-ahead, winning or crucial insurance run is at 3rd base with less than two outs. In cases like this, if a ball is hit right to an infielder, the infielder usually has a chance to throw out the runner trying to score. However, any ground ball not hit at an infielder will usually have a good chance to score the runner, plus the batter reaching base safely, versus if the infield plays back. When the infield plays back, it does make it more likely for the run to score, but the infielders are more likely to get the batter out via a ground out.
In sports, the term diamond sports refers to recreational variants of baseball, a bat-and-ball sport. The most popular and closely related sport to baseball is softball, with the two sports being administered internationally by the World Baseball Softball Confederation, alongside Baseball5.
