    Endorsed by Many Major League Umpires!

    Joe Brinkman (former MLB Umpire and Crew Chief #15) says that the authors’ “understanding of the relationship between baseball’s rules and on-field umpiring is unparalleled.”

    Many of the younger umpires in Major League Baseball learned baseball’s rules from this innovative manual. Listen to what some of the best young umpires in the world have said about our manual:

    Field Culbreth (MLB #25) calls the Jaksa/Roder manual, “the last rulebook you will ever need.”

    Jeff Nelson (MLB #45), an umpire renowned for his rules knowledge, tells about how he studied from the manual and then chose to teach from it.

    Marty Foster (MLB #60) was flustered after reading the Official Rules, but read The Rules of Professional Baseball and gained “newfound confidence” that he credited with helping him make the Major Leagues.

    Mark Wegner (MLB #47) uses the Jaksa/Roder manual to “brush up” on the rules before every season.

    Eric Cooper (MLB #56) finds that The Rules of Professional Baseball is the only place he can go to quickly find a rule and its interpretation.

    Be sure to read the full endorsements written by these and other experts.

    Baseball’s Narrowest Door:
    How to Become a Professional Umpire

    By Rick Roder

    Branch B. Rickey, grandson of Branch Rickey and president of the Pacific Coast League, said, “For anyone with interests in the field of baseball officiating, this book is contagious.”

    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.”

    Ted Barrett, MLB umpire, stated, “As usual, Roder exceeds all expectations when he sits down to do a book…it’s a unique and interesting look at the profession you won’t find anywhere else.”

    As an added bonus, the book contains many interesting MLB umpire records, quotes, accomplishments, and facts, giving you an idea of the accumulated legacies of this great profession!
