In 1996, a brassy young team of experts produced a guide to baseball statistics. Printed on a photocopier, its distribution, which was in the low 300s, was limited to friends, family, and die-hard stat-heads. Fifteen years later, the Baseball Prospectus annual regularly hits the NY Times best-seller list and has become an indispensable guide for the serious fan. In their new volume of essays, Extra Innings, the team at Baseball Prospectus integrates statistics, interviews, and analysis to deliver 20 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. They weigh in on the question of when should stars like Jeter and Pujols retire. In an era when statistics matter more than ever, Extra Innings analyzes and interprets the numbers side of the game better than any other book. The authors never lose sight of the value of leadership and performance under pressure as they help explain the beauty and logic behind America"s pastime.
