Is he simply not the pitcher we all thought he was after the first few starts? Is he just a 21 year old pitcher struggling with his control?
I think it's the latter, once the Reds are out of it for sure I wouldn't mind seeing them send him down to AAA to work on hitting his spots in non-threatening game situations. Then give him a fresh start at the beginning of next season.
Oh, and hold him out of winter ball please, those are just unnecessary pitches he's throwing.
