Oakland Athletics
Jack Perkins has thrown 1,520 pitches that have been tracked by the PITCHf/x system between 2023 and 2026, including pitches thrown in the MLB Regular Season, The World Baseball Classic, Spring Training and Fall/Winter Ball. In 2026, they have relied primarily on their Fourseam Fastball (97mph) and Slider (86mph), also mixing in a Sinker (96mph), Change (90mph) and Cutter (95mph).
In 2026, compared to other RHP:
Their fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, generates fewer whiffs/swing compared to other pitchers' fourseamers, has some natural sinking action and has well above average velo. Their slider sweeps across the zone, generates fewer whiffs/swing compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders and has some two-plane movement. Their sinker (take this with a grain of salt because they've only thrown 12 of them in 2026) generates an extremely high number of swings & misses compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, is blazing fast and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 8 of them in 2026) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' changeups, dives down out of the zone and results in more flyballs compared to other pitchers' changeups. Their cutter (take this with a grain of salt because they've only thrown 7 of them in 2026) is thrown at a speed that's borderline unfair, generates an extremely high number of swings & misses compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has little cutting action.
