Well, once Jung is called up, does Ibanez have a role with the Tigers? I would hope/think at some point that Keith progresses to be an everyday player. Jung might be on the platoon plan for his rookie season. Does he eventually get squeezed out? If he does, that's baseball and it wouldn't be tough to move him.
But for right now, does he have value for a contender as a RHH, not necessarily move him before his arbitration years (which shouldn't be expensive).
