Here are the current OFers with the possiblity of another one added either via trade or free agency.
Who'll be the odd man (men) out? I think the only thing possibly saving Mayberry is there are few options when it comes to RH hitters on this team. Nix is hanging on only because he has a guaranteed contract, but isn't needed at 1B anymore with Ryan coming back. Brown's in limbo IMO - if the Phils decide to hang onto Nix, he could be moved. Ruf should go down to AAA, but fans want to see him play and he can give some 1B relief so Howard can rest. I think Rule V pick Inciarte will actually stay on the roster. He adds speed off the bench and can be a late-inning defensive replacement in one of the corners.
We'll have to see who (if anybody) is signed/traded for to play RF or LF to get a better idea.
