At this point, it's clear from watching his inconsistency at AAA that this year is not going to be a smooth one. It's clear you haven't watched lately. Then his MLB debut will be vs the Yankees? Probably not. Why not, what if he did well? After the break: the Angels, Mariners, Astros, White Sox, Cleveland, and the White Sox again. These are all pretty light hitting teams right now, apart maybe for CLE. I can see the argument for him succeeding. if he fails against that assortment of lesser teams, there will be a lot of confidence needing to be rebuilt. They're still major league teams, I don't think he's going to suffer untold emotional damage from a little bit of adversity. Why don't we just go with the succeeding arguement, it makes far more sense. I would think that if you wanted to give him a 'cup of coffee' then bring him up for that double header against The Sox on August 9th. He might get rocked or he might do well either way it's only one game, not enough to shake any confidence and certainly enough to whet the appetite. Odds are if he stays at AAA through then he'll be darn close to his innings limit anyway. Or he can spend the off season bitter and bewildered at why he didn't get a legitimate shot at an MLB rotation most people think he's already better than.
