You are kidding, right? Did you see the lineup he pitched against? There was not one starter in the lineup for the Orioles and you are claiming that he has his "stuff" back.
Don't get me wrong, it was a solid performance, but I would expect someone in his position to pitch like that facing a AAAA or AAA lineup. It is encouraging that he is making progress, but I think it is a stretch to claim he has his "stuff" back based off of him pitching 2.2 innings against a weak lineup.
