He played 1 full season at SS with 70 Es in the ML, but that was a few years ago and his ratings were much lower then. He 25, so I assume he's developed about as much as he's going to. He's a good hitter and moreso as a SS. As has been said, he won't kill you there. If your other options are not that much better defensively, I'd go with him at SS. But it also depends on what your options are at the other positions where you might be considering playing him.
