Oakland Athletics
Although they have not thrown an MLB pitch in 2025, Michael Kelly threw 1,706 pitches that were tracked by the PITCHf/x system between 2022 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they relied primarily on their Slider (84mph) and Fourseam Fastball (95mph), also mixing in a Cutter (89mph). He also rarely threw a Sinker (94mph) and Change (88mph).
In 2024, compared to other RHP:
Their slider sweeps across the zone, has exceptional depth, generates fewer whiffs/swing compared to other pitchers' sliders and results in more flyballs compared to other pitchers' sliders. Their fourseam fastball has heavy sinking action, generates a high number of swings & misses compared to other pitchers' fourseamers, has well above average velo, results in somewhat more groundballs compared to other pitchers' fourseamers and has slightly less natural movement than typical. Their cutter has heavy sink, has sweeping cut action and generates fewer whiffs/swing compared to other pitchers' cutters. Their sinker (take this with a grain of salt because they've only thrown 3 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 slightly above average velo and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 1 of them in 2024) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, has an obvious armside fade, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
