I don't think the staunchest supporter of this move wants Gathright to be given a chance to start. It's pretty much the last spot on the bench or bust. Even if the Cubs traded Pie in a mega deal for Peavy, I still don't see the need for Gathright. He'd essentially replace Pie, who didn't have a roster spot to speak of, either. And if the plan is to bring in someone to play RF, the logjam in the OF means one of Micah Hoffpauir or Joey Gathright is the 25th man. In the AL, you can hide a speedy, defensive OF with little bat on the end of your roster, because PH's aren't nearly as needed as in the NL. That you need a productive PH to bat for the pitcher generally two times a game should make the decision quite easy for the manager. Hoffpauir, to me, is way more valuable at the end of the bench than Joey Gathright. If you need to bat for the pitcher in the middle of an inning with a runner on, then Hoffpauir is obviously the choice. But if you're making a pitching change and need to double-switch because the pitcher is due up first in the next half-inning, Gathright is better both because he's the superior (and more versatile) fielder and also because he makes for a better leadoff guy (assuming both can maintain similar OBPs, which is certainly open to debate).
