Toronto Blue Jays
Although they have not thrown an MLB pitch in 2024, Zach Stewart threw 1,808 pitches that were tracked by the PITCHf/x system between 2011 and 2013, including pitches thrown in the MLB Regular Season and Spring Training. In 2013, they relied primarily on their Fourseam Fastball (90mph), Sinker (89mph) and Cutter (86mph), also mixing in a Change (84mph). He also rarely threw a Slider (83mph).
In 2013, compared to other RHP:
Their fourseam fastball has below average velo, has some natural sinking action and has slightly less natural movement than typical. Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has below average velo and has less armside run than typical. Their cutter has heavy sink, generates a high number of swings & misses compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has slightly below average velo and has strong cutting action. Their change generates more whiffs/swing compared to other pitchers' changeups, results in many more groundballs compared to other pitchers' changeups and has some natural sink to it. Their slider (take this with a grain of salt because they've only thrown 1 of them in 2013) is basically never swung at and missed compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders, has much less depth than expected and has primarily 12-6 movement.
