General principles

The Sabermetric Manifesto by David Grabiner (1994) begins:

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

It may, however, attempt to settle questions such as "Was Willie Mays

?" 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 he was caught stealing) and then reaching a tentative conclusion on the basis of these individual studies.

Sabermetricians frequently question traditional measures of baseball skill. For instance, they doubt that batting average
Batting average
Batting average is a statistic in both cricket and baseball that measures the performance of cricket batsmen and baseball hitters. The two statistics are related in that baseball averages are directly descended from the concept of cricket averages.- Cricket :...

 is as useful as conventional wisdom says it is because team batting average provides a relatively poor fit for team runs scored. Sabermetric reasoning would say that runs win ballgames, and that a good measure of a player's worth is his ability to help his team score more runs than the opposing team. This may imply that the traditional RBI is an effective metric; however, sabermetricians also reject RBI, for a number of reasons. Rather, sabermetric measures are usually phrased in terms of either runs or team wins. For example, a player might be described as being worth 54 runs more than a replacement-level player at the same position over the course of a full season, as the sabermetric statistic VORP can indicate.

Sabermetrics is concerned both with determining the value of a player or team in current or past seasons and with attempting to predict the value of a player or team in the future. Many areas of study are still in development, specifically in the area of performance measurement.

Examples of sabermetric measurements
