If last night (or all his starts this season) are with an "off changeup", I'd love to see what he could do when it was on. I think he's in A Ball because of the impending innings limit and the depth of prospects residing in the Padres system. They'll push him up when the other moving parts in the Padres pitching farm, who are capable of throwing more innings, allow it. He's pretty much dominated every outing, so the insinuation that the changeup isn't ready or that he's still a work in progress in the California League seems like convenient rationalization. He's obviously doing something to fool hitters. I doubt it's an underdeveloped changeup which he has no feel for. Also, the biggest fear I've had is that pitchers with dominant changeups can often be fools gold at the lower levels and tend to not replicate their success at the higher levels. If he's capable of producing last night's results with a less-than-on changeup that he's not throwing often, then I get the feeling that it's not just his changeup that's producing these results. FWIW, I'm also not a fan of his throwing motion, but I regard all pitchers as injury risks.
