He seems more like a singles hitter, but he's still young and if he added some muscle, he may develop more power. He's patient at the plate, so if he sees something he can hit and just drive it, he might become a doubles hitter. I'd hate to see him think he was a power hitting shortstop and have his OBP go down and his Ks up. I do think he did a fine job last year.
The more interesting story is how Flores develops and what that would mean for Murph.
