During my B-R scan this morning, I was looking at the International League and trying to find a "young" CF with resume of good CF leather: I can't figure out how to do a CF AAA search...so I have to wade through each team!
Ben Gamel in Scranton, Dalton Pompey in Buffalo, Darin Mastroianni in Syracuse, Jackie Bradley (who has a +dWAR CF MLB glove), Julio Borbon in Norfolk (he was a +1.4 CF glove in Texas in '10), Trayce Thompson in Charlotte (But he's had a great initiation for the White Sox and may be off-limits), Abe Almonte (Really!) in Columbus, Daniel Fileds in Toledo.
On the other hand, we do have a + CF glove on the squad. It would mean you move Marte off of SS, however.
The Yankees didn't seem to think that Flores was a CF guy, but liked him in LF. I'm assuming they were right.
And I reiterate, I would give Kivlehan a ton of CF reps this winter. I want to see what he has there. He's certainly "athletic!" He'll hit 20+ homers, too. I don't know if he has the CF chops, but I want to see.
And I bet you could get John Jay from the Cards. The Cards also have Rafael Ortega down in Memphis. He has a gawdy RF/9 in CF this year, and a great eye. Check him out.
