When John Dewan's Fielding Bible was published early in 2006, it easily represented the biggest leap forward in defensive metrics ever. Three years later, in The Fielding Bible Volume II, Dewan has taken another big leap forward, not only converting his Plus/Minus rating into runs saved, but also adding in bunt runs saved (for corner infielders), double play runs saved (for middle infielders), outfield arm runs saved, earned runs saved (for catchers), and stolen base runs saved (for pitchers and catchers).
No longer do we need to wonder whether Bobby Crosby's excellent work at turning the double play outweighs his poor range: last year, he was the best in the business at turning the double play, but his four GDP Runs Saved pale in comparison to his 10 Plus/Minus Runs Allowed. Conversely, Alfonso Soriano's underrated arm made him the most valuable defensive left fielder in the game: despite having saved just nine Plus/Minus runs over the past three years, his whopping 33 runs saved via his throwing arm puts his total of 42 runs saved well over the speedy Carl Crawford's three-year total of 22 (19 Plus/Minus, 3 arm).
This is information you cannot get anywhere else, information you need to fully understand the game of baseball. Without The Fielding Bible Volume II, you might wonder why the Athletics signed the 31-year old Mark Ellis to a 2-year, $11 million deal after he batted .233 last year. But at the end of the book, there is a chart adding up players' runs created on offense, runs created on defense, and baserunning runs and using a nifty positional adjustment created by Bill James to compare the players across the diamond. We find that Ellis was a more valuable player overall last year than Alfonso Soriano, Garrett Atkins, Carlos Lee, Jim Thome, J.D. Drew, and a host of other players who each make way more money than Ellis does and each of whom the average fan would consider a better player than Ellis, hands down.
That is the advantage that the Fielding Bible gives you: the ability to understand an integral part of the game of baseball that had remained hidden for so long. Don't analyze baseball without it.
