He doesn't need to prove he can dominate AAA. We all know he can. He needs to prove in AAA that he is doing the things he needs to do to succeed at MLB, and that stuff won't necessarily show up in the box scores. We all DONT know that he can do that, because he certainly didn't do it in MLB last year. His time away matters in that case because he gave the coaches no opportunity to observe and pitched very little on top of it. In the same token, both Duffey AND Mejia have looked good this spring. If they didn't, Berrios would likely still be in the running. Now on Meyer, I'll freely admit that from an outsider's perspective, something doesn't look right there, though in 2014 I think he was going to get called up but managed to get hurt instead. It's hard to ignore that little piece. He's one to watch. I thought the trade was a bad idea.
