Baseball statistics include a variety of metrics used to evaluate player and team performance in the sport of baseball.
In baseball, an earned run is any run that was fully enabled by the offensive team's production in the face of competent play from the defensive team. Conversely, an unearned run is a run that would not have been scored without the aid of an error or a passed ball committed by the defense; it is "unearned" in that it was, in a sense, "given away" by the defensive team.
A base on balls (BB), better known as a walk, occurs in baseball when a batter receives four pitches during a plate appearance that the umpire calls balls, and is in turn awarded first base without the possibility of being called out. The base on balls is defined in Section 2.00 of baseball's Official Rules, and further detail is given in 6.08(a). Despite being known as a "walk", it is considered a faux pas for a professional player to actually walk to first base; the batter-runner and any advancing runners normally jog on such a play.
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 advancing 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, homerun or homer 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.
Sabermetrics is the original or blanket term for sports analytics, the empirical analysis of baseball, especially the development of advanced metrics based on baseball statistics that measure in-game activity. The term is derived from the movement's progenitors, members of the Society for American Baseball Research (SABR), founded in 1971, and was coined by Bill James, who is one of its pioneers and considered its most prominent advocate and public face.
In baseball, the strike zone is the area 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.
In baseball, a foul ball is a batted ball that:
Edward Augustine Walsh was an American pitcher and manager in Major League Baseball, nicknamed "Big Ed". From 1906 to 1912, he had several seasons where he was one of the best pitchers in baseball. Walsh holds the record for lowest career earned run average, 1.82. He is one of two modern (post-1901) pitchers to win 40 or more games in a single season, and the last pitcher to do so. He is the last pitcher from any team to throw more than 400 innings in a single season, a feat he accomplished in 1907 and 1908. Though injuries shortened his career, he was inducted into the Baseball Hall of Fame in 1946.
Throughout baseball's history, the rules have frequently changed as the game continues to evolve. A few typical rules most professional leagues have in common are that four balls are a base on balls, three strikes are a strikeout, and three outs end a half-inning.
A baseball is the ball used in the sport of baseball. It consists of a rubber or cork center wrapped in yarn and covered with white natural horsehide or cowhide, or a synthetic composite leather. A regulation baseball is 9 to 9.25 inches in circumference i.e. 2.86 to 2.94 inches in diameter, with a weight of 5 to 5.25 ounces.
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.
The live-ball era, also referred to as the lively ball era, is the period in Major League Baseball since 1920. It contrasts with the pre-1920 period known as the "dead-ball era". The name "live-ball era" comes from the dramatic rise in offensive statistics, a direct result of a series of rule changes that were colloquially said to have made the ball more "lively". Upon entering the live-ball era, baseball regained relevance and exploded in popularity.
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.
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.
The 1901 Detroit Tigers season was the Tigers' first in Major League Baseball. The team was a charter member of the American League, which was originally formed as the minor-league Western League, of which it had also been a charter member. The Tigers finished in third place with a record or 74–61, 8+1⁄2 games behind the Chicago White Stockings. Most of Detroit's home games were played at Bennett Park, with Sunday games played at Burns Park due to Detroit's blue laws.
The 1968 Major League Baseball season was contested from April 10 to October 10, 1968. It was the final year of baseball's pre-expansion era, in which the teams that finished in first place in each league went directly to the World Series to face each other for the "World Championship."
In baseball statistics, earned run average (ERA) is the average of earned runs allowed by a pitcher per nine innings pitched. It is determined by dividing the number of earned runs allowed by the number of innings pitched and multiplying by nine. Thus, a lower ERA is better. Runs resulting from passed balls, defensive errors, and runners placed on base at the start of extra innings are recorded as unearned runs and omitted from ERA calculations.
An emery ball is an illegal pitch in baseball, in which the ball has been altered by scuffing it with a rough surface, such as an emery board or sandpaper. This technique alters the spin of the ball, causing it to move in an atypical manner, as more spin makes the ball rise, while less spin makes the ball drop. The general term for altering the ball in any way is doctoring. The emery ball differs from the spitball, in which the ball is doctored by applying saliva or Vaseline. Vaseline or saliva smooths the baseball, while the emery paper roughens it.
