Pitch Repertoire At-A-Glance

Justus Sheffield has thrown 5,147 pitches that have been tracked by the PITCHf/x system between 2018 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they have relied primarily on their Sinker (91mph) and Slider (81mph), also mixing in a Change (86mph). He also rarely throws a Fourseam Fastball (92mph) and Cutter (85mph).


In 2022, compared to other LHP:
His sinker has surprisingly little armside run and has some natural sinking action. His slider sweeps across the zone, generates fewer whiffs/swing compared to other pitchers' sliders and has some two-plane movement. His change is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone, is much firmer than usual, has slight cut action and results in somewhat more groundballs compared to other pitchers' changeups. His fourseam fastball has heavy sinking action, has much less armside movement than typical, generates fewer whiffs/swing compared to other pitchers' fourseamers and has essentially average velo. His cutter (take this with a grain of salt because he's only thrown 13 of them in 2022) has heavy sink and has sweeping cut action.
