I realize he's still the youngest pitcher on the staff but he does now have a fair amount of major league experience. It appears as if he's really plateued and in my very humble and very unprofessional opinion, I'm not entirely certain that he's going to get much better than he is right now. A lot of good starts but no real domination mixed in with a lot of very mediocre starts as well.
I'm thinking that maybe he doesn't have the right kind of mental toughness to dominate in this game. I have this feeling that he thinks way too much about what kind of pitch he's going to throw and in what count etc etc instead of just clearing his mind and throwing the ball. As I said before, I'm no expert on baseball but he just looks like he's always pitching tentaively and I'm not so sure he's going to break out of that.
