This is one of the best baseball books I have ever read, and that is saying something. Lewis’ focus is on Billy Bean, the GM of the Oakland Athletics. Because Oakland is a small-market team, Bean must use his brain to tease out the players who can help his team, at a reasonable cost. This makes him a sort of anti-Steinbrenner. Lewis goes into some detail on how Bean manages to field competitive teams almost every year under dire fiscal constraints.
