In his new book, "Moneyball," author Michael Lewis follows Oakland A's general manager Billy Beane and examines Beane's draft philosophy -- a performance-based approach that concentrates on college players and emphasizes one key statistic above all others: on-base percentage.

Following are the draft-eligible college players who had the highest OBPs last season. Also included are their walks per official at-bat, indicative of plate discipline (a characteristic Beane covets):
