He usually has OK location, not pinpoint precision. And he has movement on his fastball, but not great movement. He throws fastball/slider, but it's really more of a 4 seam fastball/ 2 seam cut fastball.
No curveball along with the AWOL splitter means little change of speeds, and everybody looking fastball. You can tell by the increase in walks, increase in pitches thrown, and number of two-strike foul balls that he's not as effective as two or three years ago.
Throwing mid to high 90's just isn't enough to throw it by hitters anymore, not without a string to pull or other pitch to keep the hitters honest.
