Same thing's were said about Martin, Torkelson, Vaughn, Brujan, Franco, Kelenic, Big Nate, etc...
Also, Norris said that, I'm sure he'll move up in the rankings, he also said... "But right now he needs to work on commanding a pitching staff. That might be the biggest issue at this point but that will come with time."
If he continues as he is we might see him slipped onto the roster in late August if we're in contention, I think him/Martin and another SP would possibly be called up in September, I think they cut the unlimited roster promotions down to 3 or 4, IIRC, so it'll have to be justifiable. Again, we won't see him anytime soon. You mentioned calling him up now, there's no way that happens, IMO.
ETA: Oops I was wrong, it has dropped from unlimited to the 40 man, my bad.
