How is it a terrible idea to just try it out in meaningless games after the season? If it doesn't work, he'll probably just come off the bench again next year or be part of a trade package. This isn't set in stone. Because he in no way a middle infielder. That ship sailed a long time ago when he was Li'l Fox. If they want to be trade bait play him where you can best minimize his defensive shortcomings. Learning an entirely new positon and having to lose a bunch of weight to do so also has a good chance of being a pretty big speedbump in him maintaining his offensive success, too. All around this is a terrible, terrible, exceptionally stupid idea and would be a complete waste of time.
