In the case of UZR, the shortcomings in precision are large enough to drive a truck through, obviously, as it's sort of like trying to measure the thickness of a sheet of paper with an old wooden ruler. (hints: a. look at the size of the zones, b. consider that balls are denoted as "hard", "medium", and "soft" in velocity... imagine if we measured pitched ball speeds with such crude categories!) Hit F/X can't get here fast enough! All that aside, I'm sure there is a positive correlation between actual fielding skills and UZR/150 measures, and it's fun to see things like this... I'd say that we can be pretty sure Juan Rivera's legs are back at 100%, if not 120%. lol.<div class="comment-remix-meta"><a href="#" class="replyto" onclick="replyto('3756','Rob McQuown'); return false;">Reply</a> - <a href="#" class="quote" onclick="quote('3756','Rob McQuown','When a metric gives a result that Nick Green is the best defensive shortstop in the AL - even for half a season - it\'s a good time to investigate the limitations of precision on said metric.

I think Brandon Phillips is the only lock among these guys since that award is more of a popularity/fielding percentage contest.<div class="comment-remix-meta"><a href="#" class="replyto" onclick="replyto('3753','markschruender'); return false;">Reply</a> - <a href="#" class="quote" onclick="quote('3753','markschruender','It will be interesting to see how many of these guys win gold gloves.
