The best seat in baseball, but you have to stand: The game as umpires see it

Very few people know what the rigours and stresses of a pro sport official are as well as the personal setbacks and of course the professional flaws. This book has all of the above, excellently written and clearly shows what being a major sports league's messenger (since umpires just enforce the rules) is really like. Just as now, the dealings with overpaid, spoiled players, coaches and managers are well described. One of the best books I've ever read.
