Oakland Athletics
Zach Jackson has thrown 1,430 pitches that have been tracked by the PITCHf/x system between 2021 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Fourseam Fastball (92mph) and Curve (82mph), also mixing in a Change (85mph).
In 2024, 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 a high number of swings & misses compared to other pitchers' fourseamers, has essentially average velo and has slightly less natural movement than typical. Their curve generates an extremely high number of swings & misses compared to other pitchers' curves, has primarily 12-6 movement, is much harder than usual, results in more flyballs compared to other pitchers' curves and has little depth. Their change (take this with a grain of salt because they've only thrown 11 of them in 2024) generates an extremely high number of swings & misses compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
