When the change comes around, he'll be the clear #2 - 100 pitches and he hit 95, he's now 94-95 on a consistent basis, with a curve and slider. But he needs that changeup to be a top pitcher. Down the road, if the slider doesn't improve, I can see them working with him on a cutter.
Talking about cutters, it's made the difference with Alvarado, who throws 98-100 but without great movement, but pair that with a 95 MPH cutter, lights out!
