Sabermetrics is the analysis of baseball through objective evidence, especially baseball statistics. Baseball is a Bat-and-ball Sport played between two teams of nine players each Statistics play an important role in summarizing Baseball performance and evaluating players in the Sport. The term is derived from the acronym SABR, which stands for the Society for American Baseball Research. Acronyms, initialisms, and alphabetisms are Abbreviations that are formed using the initial components in a phrase or name The Society for American Baseball Research was established in Cooperstown New York, in August 1971 It was coined by Bill James, who was among its first proponents and has long been its most prominent and public advocate. George William “Bill” James (born October 5, 1949, in Holton Kansas) is a Baseball writer historian and statistician whose work has been
From David Grabiner's Sabermetric Manifesto:
It may, however, attempt to settle questions such as "Was Willie Mays faster than Mickey Mantle?" by establishing several possible parameters for examining speed in objective studies (how many triples each man hit, how many bases each man stole, how many times was he caught stealing) and then reaching a tentative conclusion on the basis of these individual studies.

Sabermetricians frequently call into question traditional measures of baseball skill. For instance, batting average is generally considered by them to be a statistic of limited usefulness because it turns out to be a poor predictor of a team's ability to score runs. Batting average is a Statistic in both Cricket and Baseball measuring the performance of cricket batsmen and baseball hitters, respectively  A more typical sabermetric reasoning would say that runs win ballgames, and that therefore a good measure of a player's worth is his ability to help his team score more runs than the opposing team. In particular, they tend to emphasize on base percentage. In Baseball statistics, on-base percentage (OBP (sometimes referred to as on-base average ', as the statistic is rarely presented as a true Percentage)
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 truly outstanding player, for example, might be described as being worth 54 runs more than an average player at the same position over the course of a full season. Runs created (RC is a baseball statistic invented by Bill James to estimate the number of runs a hitter contributes to his team Win Shares can refer to a book by Bill James or the statistic explained in the book Pete Palmer is an American Statistician, and a major contributor to the applied mathematical field referred to as Sabermetrics. Total player rating (TPR also known as Batter-Fielder/Pitcher Wins (BFW/PW is a metric for measuring the value of Baseball players and to enable players to be
Sabermetrics is concerned both with determining the value of a player in past seasons and with trying to predict the value of a player in the future. While many areas of study are still in development, it has yielded a number of interesting insights into the game of baseball and in the area of performance measurement.
Some sabermetric measurements have entered mainstream baseball usage, especially OPS (on-base plus slugging) as well as WHIP (walks plus hits per inning pitched). On-base plus slugging (OPS is a baseball statistic calculated as the sum of a player's On-base percentage and Slugging percentage. In Baseball statistics, Walks plus hits per inning pitched ( WHIP) is a sabermetric measurement of the number of baserunners a Pitcher

Artistic gymnastics World Artistic Gymnastics Championships: Men's all-around champion Ivan Ivankov, Belarus 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. Since the Athletics have lower revenues and are considered a small market team, Beane's use of sabermetrics to capitalize on what are perceived to be undervalued talents is sometimes credited with keeping the A's competitive with larger market teams like the Yankees and Red Sox. The New York Yankees are a professional baseball team based in the borough of The Bronx, in New York City, New York. The Boston Red Sox are a Professional baseball team based in Boston Massachusetts, and are the reigning (2007 World Series Champions. 
Before the Oakland Athletics pioneered sabermetrics in action, rigorous statistical analysis of potential player performance was rare. In 2003, Michael Lewis published Moneyball about Billy Beane's use of a more quantitative approach. Artistic gymnastics World Artistic Gymnastics Championships: Men's all-around champions Paul Hamm, USA, Michael Lewis (born October 15, 1960, New Orleans Louisiana) is an American contemporary Non-fiction author Moneyball The Art of Winning an Unfair Game (ISBN 0-393-05765-8 is a book by Michael M This chronicle of Beane's success at Oakland became a classic. The technique is based on skill measurement, estimates the future value of the skills, and especially on the orchestration of the skills into a successful organization.
Now,(at the beginning of the 2008 spring training,) "Sabermetric" thinking has become pervasive. In real sports, in fantasy sports, and indeed, in almost every economic activity, Sabermetrics has fostered a huge appetite for better methods. Finding efficient ways of meeting goals, or, "Winning" invigorating interest in applied statistical analysis.
