Since we're talking reality check, here, how many months does Choo get before they move him to Left Field permanently?
He's next to dead last in the Majors among Centerfielders in UZR/150 at -30.2 (Matt Kemp is worse).
Xavier Paul and Chris Heisey are 3rd and 5th respectively among National League Left-fielders who have played at least 100 innings in Left.
Jay Bruce is 12th in the National League among Right Fielders who have played at least 100 innings in Right. Bruce's UZR/150 is -2.6.
They can all be looked up here:
Would Choo be offended being put in Left? Would he be thankful to be back in familiar ground?
Heisey can play Center, and I've always felt that he can play it as good as Stubbs, if not better. Stubbs isn't exactly tearing it up in Cleveland defensively this year.
When Hamilton is ready, shouldn't he play Center anyway? If this is the case, why even go through this experiment of having Choo play Center? Certainly they would have to be interested in retaining his services beyond this season, considering how much they gave up to get him. If I wanted Choo beyond 2013, I never would have considered playing him in Center with a very capable Heisey available to play Center and a very capable Hamilton on his way.
If Choo doesn't improve Defensively significantly by the end of June, I would put him in Left to stay and then roll the dice with Heisey and Paul in Center.
