If he's subbing for Kepler or Rosario against LH pitching, he's not DHing. If he's DHing, both Rosario and Kepler (and Mauer) are in the lineup against LHers. Or Santana, I guess, which doesn't thrill me. I don't see how that helps much. If they want to give him a try as the fourth OFer, I'm fine with that, even if I think he'll eventually fail. But he doesn't help at DH, They need a RH DH/1b...
