For nearly 10 years, Jay Jaffe has talked baseball and beer every Wednesday afternoon with me on Sportstalk. Tomorrow night, the SI.com write will be signing copies of his new book, The Cooperstown Casebook at the El Paso Chihuahuas game. Jay's second appearance in the Sun City is sponsored by Longhorn Distributing.

The book is Jay's first and takes a sabermetric look at the Baseball Hall of Fame. Over the years, Jaffe has developed his own metric for analyzing a player's Hall of Fame resume. His JAWS (Jaffe WAR Score system) has been adopted by Baseball Reference and other websites as well as individuals who take a closer look at a baseball player's Hall of Fame resume. The Cooperstown Casebook is a must for any baseball fan and Jay will also be throwing out the first pitch tomorrow night as well as spend an inning in the radio booth with Tim Hagerty.
