In the numbers-obsessed sport of baseball, statistics don't merely record what players, managers, and owners have done. The revolution in baseball statistics that began in the 1970s is a controversial subject that professionals and fans alike argue over without end. In separate chapters covering every aspect of the game, from hitting, pitching, and fielding to roster construction and the scouting and drafting of players, the experts at Baseball Prospectus examine the subtle, hidden aspects of the game, bring them out into the open, and show us how our favorite teams could win more games. This is a book that every fan, every follower of sports radio, every fantasy player, every coach, and every player, at every level, can learn from and enjoy.
