Runs Created
Runs created (RC) is a baseball statistic invented by Bill James to estimate the number of runs a hitter contributes to their team. Purpose James explains in his book, ''The Bill James Historical Baseball Abstract'', why he believes runs created is an essential thing to measure:With regard to an offensive player, the first key question is how many ''runs'' have resulted from what he has done with the bat and on the basepaths. Willie McCovey hit .270 in his career, with 353 doubles, 46 triples, 521 home runs and 1,345 walks -- but his job was not to hit doubles, nor to hit singles, nor to hit triples, nor to draw walks or even hit home runs, but rather to put runs on the scoreboard. How many runs resulted from all of these things? Runs created attempts to answer this bedrock question. The conceptual framework of the "runs created" stat is: RC = \frac where *A = On-base factor *B = Advancement factor *C = Opportunity factor Formula Basic runs created In the most basic runs cre ...

Baseball Statistics
Baseball statistics play an important role in evaluating the progress of a player or team. Since the flow of a baseball game has natural breaks to it, and normally players act individually rather than performing in clusters, the sport lends itself to easy record-keeping and statistics. Statistics have been kept for professional baseball since the creation of the National League and American League, now part of Major League Baseball. Many statistics are also available from outside Major League Baseball, from leagues such as the National Association of Professional Base Ball Players and the Negro leagues, although the consistency of whether these records were kept, of the standards with respect to which they were calculated, and of their accuracy has varied. Development The practice of keeping records of player achievements was started in the 19th century by Henry Chadwick. Based on his experience with the sport of cricket, Chadwick devised the predecessors to modern-day statist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sacrifice Hit
In baseball, a sacrifice bunt (also called a sacrifice hit) is a batter's act of deliberately bunting the ball, before there are two outs, in a manner that allows a baserunner to advance to another base. The batter is almost always put out, and hence sacrificed (to a certain degree that is the intent of the batter), but sometimes reaches base on an error or fielder's choice. In that situation, if runners still advance bases, it is still scored a sacrifice bunt instead of the error or the fielder's choice. Sometimes the batter may safely reach base by simply outrunning the throw to first; this is not scored as a sacrifice bunt but rather a single. A successful sacrifice bunt does not count as an at bat, does not impact a player's batting average, and counts as a plate appearance. Unlike a sacrifice fly, a sacrifice bunt is not included in the calculation of the player's on-base percentage. If the official scorer believes that the batter was attempting to bunt for a base hit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sabermetrics
Sabermetrics, or originally SABRmetrics, is the empirical analysis of baseball, especially baseball statistics that measure in-game activity. Sabermetricians collect and summarize the relevant data from this in-game activity to answer specific questions. The term is derived from the acronym SABR, which stands for the Society for American Baseball Research, founded in 1971. The term "sabermetrics" was coined by Bill James, who is one of its pioneers and is often considered its most prominent advocate and public face. Early history Henry Chadwick, a sportswriter in New York, developed the box score in 1858. This was the first way statisticians were able to describe the sport of baseball by numerically tracking various aspects of game play. The creation of the box score has given baseball statisticians a summary of the individual and team performances for a given game. Sabermetrics research began in the middle of the 20th century with the writings of Earnshaw Cook, one of the ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inning
In baseball, softball, and similar games, an inning is the basic unit of play, consisting of two halves or frames, the "top" (first half) and the "bottom" (second half). In each half, one team bats until three outs are made, with the other team playing defense. A full baseball game is typically scheduled for nine innings, while softball games consist of seven innings; although this may be shortened due to weather or extended if the score is tied at the end of the scheduled innings. The use of the term ''inning'' in baseball and softball contrasts with cricket and rounders, in which the term is '' innings'' in both singular and plural. Gameplay Each half-inning formally starts when the umpire calls "Play" or "Play ball". A full inning consists of six outs, three for each team; and, in Major League Baseball and most other adult leagues, a regulation game consists of nine innings. The visiting team bats in the first half-inning, the ''top'' of the inning, derived from the positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Out (baseball)
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. To signal an out, an umpire generally makes a fist with one hand, and then flexes that arm either upward, particularly on pop flies, or forward, particularly on routine plays at first base. Home plate umpires often use a "punch-out" motion to signal a called strikeout. Ways of making outs * The most common ways batters or runners are put out are when: ** The batter strikes out (they make three batting mistakes, known as ''strikes'', without hitting the ball into fair territory); ** The batter flies out (they hit the ball and it is caught before landing); ** a baserunner is tagged out (they are touched by the ball, held in an opponent's hand, while not on a base); ** a baserunner is forced ou ...

Home Run
In baseball, a home run (abbreviated HR) 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 (or hitting either foul pole) without the ball touching the field. Far less common is the " inside-the-park" home run where the batter reaches home safely while the baseball is in play on the field. When a home run is scored, the batter is credited with a hit and a run scored, and a run batted in ( RBI) for each runner that scores, including himself. Likewise, the pitcher is recorded as having given up a hit and a run, with additional runs charged for each runner that scores other than the batter. Home runs are among the most popular aspects of baseball and, as a result, prolific home run hitters are usually the most popular among fans and consequently ...

Batting Average (baseball)
In baseball, batting average (BA) is determined by dividing a player's hits by their total at-bats. It is usually rounded to three decimal places and read without the decimal: A player with a batting average of .300 is "batting three-hundred". If necessary to break ties, batting averages could be taken beyond the .001 measurement. In this context, .001 is considered a "point", such that a .235 batter is 5 points higher than a .230 batter. History Henry Chadwick, an English statistician raised on cricket, was an influential figure in the early history of baseball. In the late 19th century he adapted the concept behind the cricket batting average to devise a similar statistic for baseball. Rather than simply copy cricket's formulation of runs scored divided by outs, he realized that hits divided by at bats would provide a better measure of individual batting ability. This is because while in cricket, scoring runs is almost entirely dependent on one's batting skill, in baseball ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baserunning
In baseball, base running is the act of running from base to base, performed by members of the team at bat. Base running is a tactical part of the game with the goal of eventually reaching home base ( home plate) to score a run. Batters strive to become base runners, and to enable existing base runners to move to a subsequent base or to score. In statistics, the number of baserunners (for example those allowed by a pitcher) is denoted by the abbreviation BR. Becoming a runner A batter becomes a base runner when one of the following happens: * He hits the baseball into fair territory and is not put out, * He hits into a fielder's choice, * The defensive team commits an error that allows him to reach base, * There is an uncaught third strike, * He receives a base on balls, * He is hit by a pitch, or * A fielder (typically, the catcher) interferes with him. The batter-runner The Official Baseball Rules uses the term batter-runner to identify the batter from the time he becomes a ...

Strikeout
In baseball or softball, a strikeout (or strike-out) occurs when a batter accumulates three strikes during a time at bat. It usually means that the batter is out. A strikeout is a statistic recorded for both pitchers and batters, and is denoted by K in scorekeeping and statistics. A "strikeout looking" — in which the batter does not swing and the third strike is called by the umpire — is usually denoted by a ꓘ. Although a strikeout suggests that the pitcher dominated the batter, the free-swinging style that generates home runs also leaves batters susceptible to striking out. Some of the greatest home run hitters of all time—such as Alex Rodriguez, Reggie Jackson, and Jim Thome—were notorious for striking out. Rules and jargon A pitched ball is ruled a ''ball'' by the umpire if the batter did not swing at it and, in that umpire's judgement, it does not pass through the strike zone. Any pitch at which the batter swings unsuccessfully or, that in that umpire's j ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barry Bonds
Barry Lamar Bonds (born July 24, 1964) is an American former professional baseball left fielder who played 22 seasons in Major League Baseball (MLB). Bonds was a member of the Pittsburgh Pirates from 1986 to 1992 and the San Francisco Giants from 1993 to 2007. He is considered to be one of the greatest baseball players of all time. Recognized as an all-around player, Bonds received a record seven NL MVP awards and 12 Silver Slugger awards, along with 14 All-Star selections. He holds many MLB hitting records, including most career home runs (762), most home runs in a single season (73, set in 2001), and most career walks. Bonds led MLB in on-base plus slugging six times and placed within the top five hitters in 12 of his 17 qualifying seasons. For his defensive play in the outfield, he won eight Gold Glove awards. He also stole 514 bases, becoming the first and only MLB player to date with at least 500 home runs and 500 stolen bases. Bonds is ranked second in career Win ...
