Kelly throws mostly a 2 seam fastball. (nearly 50% vs 20% 4 seamer). His offspeed stuff is poor so his heavy fastball doesn't quite work. He got a rubber arm so I hope they keep running him out there every fifth day and see if he improves.
The approach is appalling. Take strikes, swing at ball in the dirt. We had something going in the first with 2 on and no out. The middle order then proceed to end that rally 3 pitches later. It's been this way all season.
