Despite the "a reference for the rest of us" tag-line, this isn't really a book you can just dip into; at least, not on the first time of reading. Each section carefully builds your understanding from basic principles to the highly technical. The skills sections are particularly instructive, and came as an unexpected bonus over what I was expecting from this book. I eventually decided that the best way to approach it was to read it from cover to cover.
I was initially a little dismayed at how much of this book was devoted to techniques for playing the game. I am, as a 50+ years old Englishman, never going to play this game, but I wanted to find out more about it, having been a fan for a number of years. Reading these sections, however, has given me a much greater insight into the mechanics of playing the game, and goes a long way to explain some of the less obvious actions of the players. Understanding, for example, how they all train to move into the correct position for a particular direction and flight-type of ball just goes to show how professional these players are. Of particular interest to me was how pitchers are able to deliver such speeds from a standing start: the wind-up, body rotation, and planting of the forward foot are all broken down and explained; as is the grip on the ball, and the combination of wrist and arm action for the delivery. Not only is the "how" explained, but also the "why".
It's a great read, and a wonderful insight into the game, with contributions from some of its greatest living exponents. These are names that even I, brought up outside the baseball playing world, am familiar with.
I've given it 4 stars out of 5, only because the data in the reference sections are so out of date. The book was published in 2005, and is well overdue for an update. There are at least three major league teams that have changed their names between then and now, and another three (to my knowledge) have moved statiums. Nearly all of the records mentioned have been broken, and Barry Bonds hadn't even started his epic home run record chase when it came out. It's a minor niggle, and you can at least have fun pencilling in the latest info.
