Once they get Harper in the field they could give him a look, just a question of when (and where). Guthrie's spot is still basically Pache's spot (since he can't be optioned once he's healthy again). We'll see what they really plan to do with Hall (and in the meantime Clemens isn't looking so bad). But you gotta open up that DH spot for Schwarber and Castellanos if you want to try having Marsh and Muzziotti in the same OF.
Certainly it is an area of tradeable depth. I wouldn't view Rojas as untouchable either.
