He's the type of guy I'd have around going in to a season (or more acurately going in to the prior off-season) thinking, "well, maybe if worse comes to worst I'll platoon him against lefties."
Worse never comes to worst.
First, as others have said, he'd have to progress beyond his current ratings for me to use him in the Majors at SS at all. Others are more lenient than I am with that. I put a premium on D. So if his D was good enough, I might carry his bat, but only agasinst LHP and as I said, only until I find someone better on the waiver wire, as a minor league FA or cheap ML FA.
Probably your AAA SS with a "September" call up.
