Pitch Repertoire At-A-Glance

Kyle Harrison has thrown 4,249 pitches that have been tracked by the PITCHf/x system between 2023 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (94mph) and Curve (82mph), also mixing in a Change (86mph). He also rarely throws a Slider (84mph) and Cutter (89mph).


In 2025, compared to other LHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has heavy sinking action, has well above average velo and has slight armside run. Their curve is thrown extremely hard, generates more whiffs/swing compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has little depth and has slight glove-side movement. Their change dives down out of the zone, generates more whiffs/swing compared to other pitchers' changeups and is much firmer than usual. Their slider (take this with a grain of salt because they've only thrown 4 of them in 2025) results in more flyballs compared to other pitchers' sliders and has some two-plane movement. Their cutter (take this with a grain of salt because they've only thrown 3 of them in 2025) has heavy sink, is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has well above average velo.
