Michael Kelly has thrown 1,431 pitches that have been tracked by the PITCHf/x system between 2022 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Slider (84mph) and Fourseam Fastball (96mph), also mixing in a Cutter (89mph). He also rarely throws a Sinker (95mph).
In 2024, 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 generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, has less armside movement than typical, has some natural sinking action and has well above average velo. Their cutter has heavy sink, has sweeping cut action, generates fewer whiffs/swing compared to other pitchers' cutters and results in somewhat more flyballs compared to other pitchers' cutters. Their sinker (take this with a grain of salt because they've only thrown 1 of them in 2024) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has well above average velo and has slight armside run.
