If I'm Dombrowski I'd try and convince the owners to let me just release him, it wasn't his signing and sometimes you need to cut your losses. I don't see where he fits in at all with Shaw, Hanley, Moncada and a potential signing of someone like Encarnacion next year. He's out of shape, overpaid, and his play has been horrible.
I would say trade him, but who in the hell would actually WANT him?
