My thoughts on this are depending on where were at by the trade deadline he could be moved. His contract isn't that bad for a left handed veteran reliever and there would be quite a few times that would probably take a chance on him. Will the Cubs try and move him? I don't know. Should they? Yes.
Over the offseason I was happy they resigned him with the way he pitched when he got here from Pittsburgh. That has changed however since he can't seem to find the plate and when he does they rock him.
Something should happen at the deadline with the Cubs either buying or selling.
