If you like baseball and you like stats, you'll love this book. No math skills are required, yet you can appreciate the methodical research and analysis that went into this book. It transformed the way I watch defensive plays now. The author exposes the obvious ways in which the Gold Glove has been awarded to the wrong players. Separate chapters are devoted to each position, with the author creating his own rankings by era. I didn't know that the best fielding short-stop and third baseman played side by side on the same team! If you enjoyed Moneyball, this is a must, as it applies metrics to fielding, a feat that has never before been fully accomplished. The book does not need to be read cover to cover. It is written in a user-friendly fashion that allows one to use it as a reference book as well. I highly recommend it.
