**Statistics** play an important role in summarizing baseball performance and evaluating players in the sport. Since the flow of baseball has natural breaks to it, the game lends itself to easy record keeping and statistics. This makes comparisons between players' on field performance relatively easy, and therefore gives statistics more importance in baseball than in most other sports. Statistics have been kept for professional baseball since the creation of each league. Many statistics are also available from outside of Major League Baseball, from leagues such as the National Association and the Negro Leagues. This article is about the sport. ...

## Development of statistics The practice of keeping records of player achievements was started in the 19th century by Henry Chadwick.^{[1]} Based on his experience with cricket, Chadwick devised the predecessors to modern day statistics including batting average, runs scored, and runs allowed. Henry Chadwick (October 5, 1824 â€“ April 20, 1908), often called the father of baseball, was a sportswriter, baseball statistician and historian. ...

Traditionally, statistics such as batting average (the number of hits divided by the number of at bats) and earned run average (approximately the number of runs allowed by a pitcher per nine innings) have dominated attention in the statistical world of baseball. However, the recent advent of sabermetrics has created statistics drawing from a breadth of player performance measures and playing field variables. Sabermetrics and comparative statistics attempt to provide an improved measure of a player's performance and contributions to his team from year to year, frequently against a statistical performance average.

Comprehensive, historical baseball statistics were difficult for the average fan to access until 1951, when researcher Hy Turkin published *The Complete Encyclopedia of Baseball*. In 1969, Macmillan Publishing printed its first *Baseball Encyclopedia*, using a computer to compile statistics for the first time. Known as "Big Mac", the encyclopedia became the standard baseball reference until 1988, when *Total Baseball* was released by Warner Books using more sophisticated technology. The publication of *Total Baseball* led to the discovery of several "phantom ballplayers", including Lou Proctor, who did not belong in official record books and were removed.^{[2]} 1952 Baseball Encyclopedia Hy Turkin (born May 9, 1915 in New York, New York, died June 24, 1955) was a sportswriter best known for co-editing the first baseball encyclopedia. ...

## Use of statistics Throughout much of modern baseball, several core statistics have been traditionally referenced—batting average, RBIs, and home runs. To this day, a player who leads the league in these three statistics is referred to as the "Triple Crown" winner. For pitchers, wins, ERA, and strikeouts are the most often cited traditional statistics, with a pitcher leading a league in these statistics referred to as a "Triple Crown" winner. General managers and baseball scouts have long used the major statistics, among other factors and opinions, to understand player ability. Managers, catchers and pitchers use statistics of batters against opposing teams to develop pitching strategies and set defensive positioning on the field. Managers and batters study opposing pitcher performance and motion in attempts to improve hitting. Managers often base personnel decisions for a game on statistics, such starting lineups or relief pitcher substitutions.^{[citation needed]} Batting average is a statistic in both cricket and baseball measuring the performance of cricket batsmen and baseball hitters, respectively. ...

Some sabermetric statistics have entered the mainstream baseball world that measure a batter's overall performance including On-base plus slugging, commonly referred to as OPS. OPS adds the hitter's on base percentage (number of times reached base by any means divided by total plate appearances) to his slugging percentage (total bases divided by at bats). Some argue that the OPS formula is flawed and that more weight should be shifted towards OBP (on base percentage).^{[2]} Sabermetrics is the analysis of baseball through objective evidence, especially baseball statistics. ...
In baseball statistics, on-base plus slugging (denoted by OPS) incorporates on base percentage (OBP) and slugging percentage (SLG). ...
In baseball statistics, on base percentage (OBP) (sometimes referred to as on base average (OBA)) is a measure of how often a batter gets to first base for any reason other than a fielding error or a fielders choice. ...
In baseball statistics, slugging average (SLG) is a measure of the power of a hitter. ...
In baseball statistics, total bases refers to the number of bases a player has gained with hits, i. ...
OPS is also useful when determining a pitcher's level of success. "Opponent On-base Plus Slugging" (OOPS) is becoming a popular way to evaluating a pitcher's actual performance. When analyzing a pitcher's statistics, some useful categories to consider include K/9IP (strikeouts per nine innings), K/BB (strikeouts per walk), HR/9, WHIP (walks plus hits per inning pitched) and OOPS (opponent on-base plus slugging). In baseball statistics, strikeouts per 9 innings pitched (K/9IP) is the mean of strikeouts, (or Ks) by a pitcher per nine innings pitched. ...
However, since 2001, more emphasis has been placed on Defense-Independent Pitching Statistics, including Defense-Independent ERA (dERA), in an attempt to evaluate a pitcher performance regardless of the strength of the defensive players behind him. In baseball, Defense Independent Pitching Statistics (DIPS) are statistics which measure a pitchers effectiveness based only on plays which do not involve fielders: home runs allowed, strikeouts, hit batters and walks. ...
Also important are all of the above statistics in certain in-game situations. For example, a certain hitter's ability to hit left-handed pitchers might incline a manager to provide increased opportunities to face left handed pitchers. Other hitters may have a history of success against a given pitcher (or vice versa), and the manager may use this information to create a favorable match up. The use of performance-enhancing anabolic steroids in Major League Baseball has affected the value of statistics, according to the Mitchell Report, released 13 December 2007, which concluded, in part Crystal structure of human sex hormone-binding globulin, transporting 5Î±-dihydrotestosterone. ...
The illegal use of performance enhancing substances poses a serious threat to the integrity of the game. Widespread use by players of such substances unfairly disadvantages the honest athletes who refuse to use them and raises questions about the validity of baseball records.^{[3]} ## Commonly used statistics Most of these terms also apply to softball.

The explanations below are for quick reference and do not fully or completely define the statistic; for the strict definition, see the corresponding article for each statistic.
