David Peterson has thrown 12,137 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 (91mph) and Fourseam Fastball (92mph), also mixing in a Slider (85mph), Change (85mph) and Curve (79mph).
In 2025, compared to other LHP:
Their sinker results in many more groundballs compared to other pitchers' sinkers, has less armside run than typical and has some natural sinking action. Their fourseam fastball has heavy sinking action, has much less armside movement than typical, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. Their slider results in many more groundballs compared to other pitchers' sliders and has some two-plane movement. Their change is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups, dives down out of the zone and is slightly firmer than usual. Their curve is slightly harder than usual and results in somewhat more flyballs compared to other pitchers' curves.
