David Peterson has thrown 9,707 pitches that have been tracked by the PITCHf/x system between 2020 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Sinker (92mph), Slider (85mph) and Fourseam Fastball (93mph), also mixing in a Change (84mph) and Curve (79mph).
In 2025, compared to other LHP:
Their sinker has less armside run than typical, has slightly above average velo and has some natural sinking action. Their slider results in more flyballs compared to other pitchers' sliders and has some two-plane movement. Their fourseam fastball has less armside movement than typical, has some natural sinking action and has slightly above average velo. Their change is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups, is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone and is slightly firmer than usual. Their curve results in many more groundballs compared to other pitchers' curves and is slightly harder than usual.
