I watched him pitch against Pittsburgh and was a little surprised by what I saw. Since I had nosebleed seats I couldn't see much of the pitch movement.
What I saw:
Obviously the results were good including the K's
He had a lot of weak contact
Was willing to throw breaking balls inside a lot to LH batters
Velocity was down. About 92 or 93 and highest I saw was 95. I think the Toronto gun is slow though.
Mechanics looked horrible. He had different body action, release points, arm action for all of his pitches. When throwing normal fastball it looked nice and fluid. When going with a change it was an exaggerated slowdown at the end just before release. When he wanted extra velocity or movement he had way more body rotation falling down and to his left a lot and the ball tended to miss in that direction. When throwing the breaking balls he also fell down and to his left but less exagerrated.
From what I hear he has a lot of late life, obviously I couldn't see that from my seats. And his velocity was down or the gun was low. I think it was a bit of both. I have seen him before and really liked the stuff. But this is the first time I saw him from this angle and thought his body control was beyond terrible. Maholm was similar but not as bad. But I was very surprised. Maybe it was an off day? I would love to hear from others.
IMO until he cleans this up he won't move into that upper echelon of starters. On the flip-side he has been heating up in spite of these problems and it's certainly easier to improve things like landing points and arm action versus trying to improve stuff and/or location.
