He's not excelling at AAA, especially given the expectations and his defensive liabilities. I'm not rooting against him, but I'm not holding my breath that he pans out. Ok, so his bat is excelling. His defense can be at least partially covered up by a move to the OF, where his arm might at least have some value. How is his bat "excelling?" Given the expectations and the need to overcome his defensive liabilities he needs to be beating the hell out of AAA. Relative to that he's essentially just doing well, but certainly nowhere near good enough to think he could justify being a starting corner MLB OF. His OPS is near .900. You know, excelling. Yes, a high ceiling, defensively challenged prospect is hitting in the .800's in AAA. That's not excelling. Excelling is what Rizzo did.
