If all you're going to use him for, are low leverage/mop up situations, then I'd be ok with keeping him around for a little longer. No way can he be trusted in a situation like yesterday, no matter what the availability is of other pen arms. He will absolutely let the team down in anything other than mop up duty. Preferably, I'd LOVE to see him elsewhere, but for some reason this FO wants to keep him here. He really needs a fresh start on another team, and we need to be rid of him.
