Zack Weiss has thrown 1,060 pitches that have been tracked by the PITCHf/x system between 2018 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they have relied primarily on their Slider (85mph) and Fourseam Fastball (94mph). He also rarely throws a Cutter (92mph) and Sinker (94mph).
In 2022, compared to other RHP:
His slider sweeps across the zone, generates more whiffs/swing compared to other pitchers' sliders and has some two-plane movement. His fourseam fastball has slightly above average velo and has slightly less natural movement than typical. His cutter generates an extremely high number of swings & misses compared to other pitchers' cutters, has well above average velo and has some natural sink. His sinker (take this with a grain of salt because he's only thrown 3 of them in 2022) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has slight armside run and has slightly above average velo.
