Jeff Nelson, MLB umpire, added, “It reads like one of those laid-back ‘rap sessions’ we had at Brinkman’s umpire school, which is where you really learned about the job.”

Joe Brinkman, MLB umpire and crew chief, had this to say, “Roder’s book is a vital contribution toward clearing up misconceptions about professional umpiring.”
