If he needs a challenge he should keep working at 3B defense and people are saying the reason he hasn't hit much in a month is he's bored, maybe focus and keep the nose to the grindstone. I think he was getting called up before he broke his ribs because Ramon wasn't hitting at all and he would have had enough time to win ROY if he came up and mashed. He got hurt, that sucks, and this is where we're at.
Ramon has been hitting, I wouldn't bet money that Mayo comes up and immediately hits better than Ramon. He'll get his shot this year. He's 22 in his first full season at AAA. Nobody can convince me that he has been handled poorly.
