I think the question here is how long Hughes will be on the DL. That has to be answered first. While I've been clear that I think Duffey deserves another chance to start, if this Hughes DL stint is short, it won't happen. He will need to get stretched out (though that should be easy enough as he can be set to get stretched out during Gibson or Mejia's next start). If that stint is long, I have to think they need to do it. This team will be better off with Gibson in AAA, Duffey in the rotation, and one of the AA/AAA relievers up in the pen.
