Sabermetrics is the analysis of baseball through objective evidence, especially baseball statistics. The term is derived from the acronym SABR, which stands for the Society for American Baseball Research. It was coined by Bill James, who has been its most enthusiastic (and by far its most famous) proponent. Baseball is a team sport, in which a fist-sized ball is thrown by a defensive player called a pitcher and hit by an offensive player called a batter with a round, smooth stick called a bat. ...
As with many sports, and perhaps even more so, statistics are very important to baseball. ...
The Society for American Baseball Research was established in Cooperstown, New York in August of 1971. ...
This article is about Bill James, the baseball writer and father of sabermetrics. ...
From David Grabiner's Sabermetric Manifesto:
- Bill James defined sabermetrics as "the search for objective knowledge about baseball." Thus, sabermetrics attempts to answer objective questions about baseball, such as "which player on the Red Sox contributed the most to the team's offense?" or "How many home runs will Ken Griffey, Jr. hit next year?" It cannot deal with the subjective judgments which are also important to the game, such as "Who is your favorite player?" or "That was a great game."
Sabermetricians call into question traditional measures of baseball skill. For instance, batting average is considered to be a statistic of limited usefulness because it turns out to be a poor predictor of a team's ability to score runs. Typical sabermetric reasoning would say that runs win ballgames, and so a good measure of a player's worth is his/her ability to help his/her team score more runs than the opposing team. George Kenneth Griffey, Jr. ...
Batting average is a statistic in both baseball and cricket measuring the performance of baseball hitters and cricket batsmen, respectively. ...
Accordingly, sabermetric measures - such as Bill James's Runs created and Win shares or Pete Palmer's Total player rating - are usually phrased in terms of either runs or team wins; a player might be described as being worth 54 runs more than an average player at the same position over the course of a full season, for example. Runs created (RC) is a baseball statistic invented by Bill James to estimate the number of runs a hitter contributes to his team. ...

Pete Palmer is an American baseball [statistician]], and one of the leading creators of the mathematical system referred to as sabermetrics. ...
Total player rating (TPR) is a metric for measuring the value of baseball players, and to enable players to be compared against each other even when they played for different teams, at different positions, and in different eras. ...
Sabermetrics is concerned both with determining the value of a player in a season gone by, and with trying to predict the value of a player in the future based on his past performances. These are not the same thing. For example, a player with a high batting average one year may have been very valuable to his team, but batting average is known to be a volatile stat and relying on it to remain high in future years is often not a good principle. A sabermetrician might argue that a high walk rate is a better indication that a player will retain his value in the future. In baseball statistics, a base on balls (BB), also called a walk, is used in baseball to track the performance of pitchers and batters. ...
While this area of study is still in development, it has yielded many interesting insights into the game of baseball, and in the area of performance measurement generally.
Some sabermetric measurements have entered mainstream baseball usage, especially OPS (on-base plus slugging) and, to a lesser extent, WHIP (walks plus hits per inning pitched). In baseball statistics, on-base plus slugging (denoted by OPS) is defined by the sum of on base percentage (OBP) and slugging percentage (SLG). ...
In baseball, walks plus hits per inning pitched (WHIP) is a sabermetric measurement of how many baserunners a pitcher is responsible for allowing per inning pitched. ...

Major proponents of sabermetrics Billy Beane has been the general manager of the Oakland Athletics since 1997. Although not a public proponent of sabermetrics, it has been widely noted that Beane has steered the team during his tenure according to sabermetric principles: Batters should try to get walks, traditional defensive statistics (such as errors and fielding percentage) are less important than people think, pitchers should be able to strike out batters, spending amateur draft picks on high school pitchers is a bad use of resources, etc. What's remarkable about this is that so few other teams in baseball apply these principles, the Boston Red Sox being a prohibitive exception, thus making the Athletics the first, best test case for sabermetrics in action. In 2003, Michael Lewis published Moneyball, a book about Beane and how his approach to running the Athletics works. In recent years, Beane assistants J. P. Ricciardi and Paul DePodesta have been hired as general managers for the Toronto Blue Jays and the Los Angeles Dodgers. There is another former major league player named Billy Bean. ...

Bill James is widely considered the father of Sabermetrics. He began publishing his Baseball Abstracts in 1977 to study some questions about baseball he found interesting, and they soon became popular with a generation of thinking baseball fans. He discontinued the Abstracts after the 1988 edition, but continued to be active in the field. His two Historical Baseball Abstract editions and Win Shares book have continued to advance the field of sabermetrics, 25 years after he began. In 2002 James was hired as a special advisor to the Boston Red Sox. This article is about Bill James, the baseball writer and father of sabermetrics. ...

John Thorn and Pete Palmer are the authors of two key books that present sabermetric statistics and readable, common-sense explanations for why it's worth thinking about them: The Hidden Game of Baseball and the series of baseball encyclopedias called Total Baseball, with David Pietrusza and the late Michael Gershman. They also include the mathematical formulae for the hard-core statisticians, but the strength of their books is the accessibility of the statistics for everyday baseball fans. Thorn is a frequent commentator for ESPN and was advisor to the Ken Burns baseball documentary film. Thorn, Palmer and Gershman provided the statistics and analysis for the Tony La Russa Baseball series of computer games. B: April 17, 1947, Stuttgart, West Germany. ...

Earl Weaver Weaver would vociferously deny any such statistical leanings, and say his baseball strategy is based on "common sense." Nevertheless, his use of what we would call sabermetric methods is well-documented. Weaver was the first baseball manager to start keeping stats about how each of his Baltimore Orioles batters did against each pitcher in the league, and the corresponding stats for each Orioles pitcher against each American League hitter. This kind of situational statistical study is one of the core concepts of sabermetrics, since the more detailed analysis gives us a far better idea of what might happen in each at-bat than more generalized numbers. Thorn and Palmer specifically identify a number of ways in which Weaver's strategies reflected sabermetric principles in their books. The computer game Earl Weaver Baseball (1987), the first comprehensive statistics-based baseball simulation game, had artificial intelligence based on Weaver's statistical principles.
