The AA outfield situation is interesting. Here's a reason to move Basabe to AAA: Charlotte's a much, much better place to hit. So while Basabe will be seeing a lot of breaking stuff and people pitching him backwards more, he'd at least be rewarded when he did hit the ball hard. Results in Birmingham sometimes don't reflect how well a guy's swinging it.
That said, Robert, Basabe, Gonzalez, and Adolfo are the key guys here. Pick what's best for them and fill guys like Booker in as needed.
