I say hold. His average is likely to end around .270-.280, but he'll put up great power numbers for a 2B, second only to Utley. I would definitely rank him in the top 4 at his position at the end of the season.
That being said, if someone offers you Pujols for him, then yes, sell high. But it must be a really high sell.
