There is no reason Sano, Kepler, and Polanco shouldn't be in AAA today. I'd leave ABW in AA for a full season. I'm glad they moved up Berrios to AAA. Here's how I'd play it: I would have Sano getting reps at 1st and in RF in addition to his time at 3rd. I would also like to see Mauer and Plouffe get time in RF. Mauer isn't going anywhere with that contract and there is no reason to trade away Plouffe yet- he's an established, productive player and we don't have enough of those on this team. I would like to see what Sano's bat would do against more experienced AAA pitching, before I'd bring him up. He's going to strike-out at the ML level, but Sano has shown the ability to reduce his K rate the more experience he gets at each level- so I'd wait for that point where he starts to reduce his K% in AAA before bringing him up to make that jump as easy as possible. I think Polanco can come up and play SS at anytime- from what little I've seen he looks ready with the bat- and he's probably no more error prone than Santana, who has no bat. Kepler, is likely almost ready to- that BB/K ratio is a thing of beauty. But he likely needs to stay in AAA until September to round off some of those rough edges. When Buxton is healthy, he needs to go to AAA. He clearly wasn't ready. Leave him there until September.
