Along with his curveball, Smeltzer throws his changeup a quarter of the time. The changeup was great at generating swings outside the zone and inducing ground balls. In terms of pitch value, this pitch was essentially league average, but that was largely due to an elevated .341 BABIP.
Smeltzer’s curveball also has a very high spin rate, with a sweeping 10-to-4 break. Similar to his changeup, it generates swings outside the zone over 40% of the time. It also had a 26.7% K rate and 1.6 pVALon just 180 thrown.
Averaging just 89 mph on his fastball, Smeltzer only throws the pitch 45% of the time. It’s no surprise that it generated a negative pitch value in 2019, despite a high 2,400 RPM spin rate. With just a 6.9% SwStr rate, Smeltzer uses this pitch to get called strikes.
The cutter is thrown with the velocity of a slider, but has cutter-like movement. With 44 cutters thrown in 2019, Smeltzer did not generate a single whiff. With a below 40% zone rate, Smeltzer could probably eliminate this pitch in 2020.
