To be more specific regarding the question of Sabermetrics. See below.

Probably the best web site for this is:


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 was among its first proponents and has long been its most prominent advocate known to the general public.

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?"
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. [1] 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.
