It isn't going to happen so I would suggest Gibby bribe someone to drop something heavy on his foot or do something to get him on the DL. Nothing serious just a minor injury excuse to DL him. He obviously needs to go to the minors and pitch.
AA will never DFA the guy so a minor league rehab stint is really Gibby,s only option. Right now it is a catch 22. If he doesn't pitch they can't fix his command or his slider, yet he can't be trusted to pitch.
