Maybe. I don't know if I'd go much higher. He may be one of those guys whose isoOBP is higher than is isoSLG. At any rate, he'd likely be an improvement over Uggla. He could be Gregor Blanco with better contact skills.
That will probably be the case, but again, when you have the worst player in the game manning 2B, even "upgrading" to a player who is merely below average is a nice boost.
