Updated with data from the 2002 season, and with new essays on superstar Barry Bonds and the first ever all- Wild-Card World Series, this new paperback edition of the 2001 SABR-Award-winning original hardcover explains why standard statistics are of limited usefulness in evaluating a player, developing an inning-by-inning strategy, or predicting which team will come out on top. The authors' most significant contribution to the seemingly endless arguments about baseball stats is their inclusion of the statistical principles of probability to analyze the game and the players.
