Sabermetrics

Sabermetrics (originally SABRmetrics) is the original or blanket term for sports analytics, the empirical analysis of baseball, especially the development of advanced metrics based on baseball statistics that measure in-game activity. The term is derived from the movement's progenitors, members of the Society for American Baseball Research (SABR), founded in 1971, and was coined by Bill James,^[when?] who is one of its pioneers and considered its most prominent advocate and public face.^[1]

The term moneyball is used for the practice of using metrics to identify "undervalued players" and sign them to what ideally will become "below market value" contracts, which debuted in the efforts of small market teams to compete with the much greater resources of big market ones.
