Dan Formosa and Paul Hamburger are, according to their back cover bio, "design experts with many decades of award-winning work and an obsession with baseball between them".
Both of those skills are on display in this revised and updated edition of their "Baseball Field Guide" (Da Capo Press). The first edition was published in 2006.
Formosa and Hamburger have rewritten what they refer to as "the vague, misleading, confusing, inconsistent, and obscure" rules of baseball. They have recast the rule book in language that is easy to understand -- for both new fans and decades-long devotees -- with simple, yet highly informative, illustrations.
Here is one of the illustrations for interference:
Pages 64-65 -- Pitching Positions:
Along the way, you'll learn 12 ways a runner can be called out, 18 ways a batter can make an out, nine ways an error can be charged, and 21 instances that warrant a player's ejection.
Formosa and Hamburger have created a real gem. I can't think of a better book that serves an introduction to the sport and how it is played. I'll be referring to the Field Guide at least as often as I do to the actual rule book ... probably more.
[Earlier this year, a Perseus Books publicity person emailed me, asking if I wanted to review this book. In an odd coincidence, I had been admiring it in a book store the previous day.]
