Between Eloy, Vaughn and Mercedes, Vaughn appears to be the best defensive LFer even though he had never played there before. The question should be who will be DH, Yermin or Eloy. Now I expect Yermin to come back down to earth by then, but if he's still raking, I'd stick with Yermin for the rest of the year. Figure out what to do over the offseason. This of course assumes Vaughn is hitting well.
