As it is, with Hughes in the rotation, you have Mejia and Berrios in AAA. That's not bad from a depth thing, but I'd argue that both really need to be in Minnesota sooner than later. Perhaps the assumption is that 2017 is not a lost season (not sure I agree), but I think the team would be better off getting both of them some major league time, and in Berrios' case, there's really nothing left to prove in the minors. Mejia didn't spend much time in AAA, so starting there isn't bad from a depth move. and yeah, if they add guys like Stewart and/or De Leon from LA, you've got to dump guys like Santiago. Heck, if there was a reason to trade Santana, that would be it too. Depth is good, but I don't see it being a good thing when your younger talent is being blocked by guys like Santiago.
