Michael Kelly has thrown 1,847 pitches that have been tracked by the PITCHf/x system between 2022 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Slider (83mph) and Fourseam Fastball (96mph), also mixing in a Cutter (89mph). He also rarely throws a Sinker (95mph).
In 2025, compared to other RHP:
Their slider is basically never swung at and missed compared to other pitchers' sliders, sweeps across the zone, has exceptional depth and results in somewhat more flyballs compared to other pitchers' sliders. Their fourseam fastball has some natural sinking action, has well above average velo and has slightly less natural movement than typical. Their cutter (take this with a grain of salt because they've only thrown 13 of them in 2025) has heavy sink, has extreme cut action, generates a high number of swings & misses compared to other pitchers' cutters and is an extreme flyball pitch compared to other pitchers' cutters. Their sinker (take this with a grain of salt because they've only thrown 7 of them in 2025) generates an extremely high number of swings & misses compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has well above average velo, has slight armside run and has some natural sinking action.
