In 1996, a brassy young team of fans produced a guide to baseball statistics. Printed on a photocopier, its distribution, which was in the low hundreds, was limited to friends, family, and die-hard stat heads. Sixteen years later, the Baseball Prospectus annual regularly hits best-seller lists and has become an indispensable guide for the serious fan.

In Extra Innings , the team at Baseball Prospectus integrates statistics, interviews, and analysis to deliver twenty arguments about today’s game. In the tradition of their seminal book, Baseball Between the Numbers , they take on everything from steroids to the amateur draft. They probe the impact of managers on the game. They explain the critical art of building a bullpen. In an era when statistics matter more than ever, Extra Innings is an essential volume for every baseball fan.
