Sean Smith has been kind enough to provide The Hardball Times with his Total Zone data for all minor league players in 2009 (for more information check minorleaguesplits.com). The Total Zone numbers are produced using play-by-play data and the results are similar to Ultimate Zone Rating (UZR) or the plus/minus system. A more detailed explanation of Total Zone can be found at baseball-reference.
Below you will find a listing of the top rated defensive players of 2009 at each position based on the amount of runs above average they saved (minimum of 100 total chances).
