A collaboration of 34 SABR members. This book includes biographies of all the umpires in the National Baseball Hall of Fame in Cooperstown, other notable arbiters, essays about professional female umpires, umpiring in the Negro Leagues, explorations of the baseball rules, umpire equipment, and much more. During the work on this book, we interviewed 56 major league umpires, former umpires, supervisors and umpire administrators, and others whose jobs cause them to interact with umpires. We hope to shed light on the umpiring profession past and present, the work involved on the field, and the arduous challenges and sacrifices it takes to become an umpire at the top of the profession. We have tried to look at the occupation from many different angles. No book can cover all facets of the job, but we hope to give readers a fuller appreciation of baseball and those charged with the integrity of the game. Contributions by David W.
