Baseball’s spring training is well under way in Florida and Arizona. While players work to make a spot for themselves and prepare for the start of the season, coaches, managers and scouts evaluate the talent they see on the fields; and they increasingly are using something called advanced defensive metrics. John Dewan is the owner of Baseball Info Solutions, and one of the authors of The Fielding Bible- Volume 3. The book is a compilation of defensive statistics. We reached him while he was in Arizona to ask him about defensive analysis in the game, and what exactly teams do with that information.
