What happens when Robbie Ray comes back? Will Clay Buchholz go back to Triple-A?

It appears, judging by the roster move the D-backs made on Wednesday to option Matt Koch to Triple-A Reno and call up reliever Jake Barrett, that they will activate Shelby Miller to take Koch's spot in the rotation the next time through. As for when Ray returns, he could replace Buchholz in the rotation, or it's possible that Miller might need some time in the bullpen as he regains his arm strength.
