Hitting HR's doesn't mean you are dominating AAA. Pull up his stats for July and look at all the k's and just a few walks. I think it would be a waste just to bring him up and be a bat off the bench. The biggest thing against him is all the prospects that seem to be DH's. Kennys Vargas,Oswaldo Arcia, and Miguel Sano. He will be the next David Ortiz when the Twins can't figure out how to get the most out of him.
