St. Louis Cardinals
Zack Weiss has thrown 3,168 pitches that have been tracked by the PITCHf/x system between 2018 and 2025, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2025, they have relied primarily on their Slider (85mph) and Fourseam Fastball (94mph). He also rarely throws a Change (86mph).
In 2025, compared to other RHP:
Their slider sweeps across the zone, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their fourseam fastball has essentially average velo and has slightly less natural movement than typical. Their change (take this with a grain of salt because they've only thrown 4 of them in 2025) is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, has a lot of backspin, is slightly firmer than usual and has slight armside fade.
