Outside of Roger Kahn's Boys of Summer, this is the best book about baseball written in the last ten years. Warning: you really have to understand the finer points of the game to appreciate it. This book is about the application of hardcore math to the thinking man's game using the best season of the Oakland A's in the last decade as an example. With a calculator, a lifetime of experience with baseball, and a keen understanding of the game, manager Billy Beane transformed a lackluster team into the team to beat.
