Pitch Type Future Grade Sitting Velocity Peak Velocity Report
FB 60 93-95 97 True plus pitch fastball that flashes better; gets some glove-side run, slight sink down and great life and "rise" up in the zone that generates weak contact and swing-and-miss. Can live around 95-97 in the early innings but settles into a mid-90s rhythm by the middle innings. Command is decent but could be better.
CV 55 82-84 87 Varies the shape on his power curve, the mid-80s variation more like a slider that is effective running down and away from RHH. The slightly slower version of this pitch has more of a 10-4 break, and he likes to use both to front-door RHH and get called strikes. This pitch flashes plus when he hits the sweet spot therein, with late and sharp downward action and just enough lateral movement. He also throws a much slower true curve on occasion, going 12-6 in the low-70s for a drastic change of pace.
CH 50 84-85 86 Doesn't throw the change often, but looks to be at least an average offering.

Stuff jumps out at you, as does athleticism and competitiveness. All of this makes him a joy to watch, but there are areas to iron out as Stiever climbs the ladder. Fastball command could improve, and I believe it will as the athleticism is there and the mechanics are sound enough. While the ability to vary the speed and shape on his curve is an asset, it doesn't always seem like there is a purpose to the alterations or that he has fully harnessed the potential of the pitch. He hasn't really needed a third pitch at this level, but he should use and refine the change as it will be necessary at some point. I believe the ingredients are here for a back end to mid-rotation starter in the big leagues.
