Zach Pop has thrown 3,995 pitches that have been tracked by the PITCHf/x system between 2021 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Sinker (96mph) and Cutter (93mph), also mixing in a Slider (85mph). He also rarely throws a Fourseam Fastball (96mph).
In 2025, compared to other RHP:
Their sinker has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers, has an obvious tail, is blazing fast and generates more whiffs/swing compared to other pitchers' sinkers. Their cutter is blazing fast, is an extreme flyball pitch compared to other pitchers' cutters, has little cutting action and has some natural sink. Their slider is basically never swung at and missed compared to other pitchers' sliders, has exceptional depth, results in many more groundballs compared to other pitchers' sliders and has short glove-side cut. Their fourseam fastball (take this with a grain of salt because they've only thrown 1 of them in 2025) generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action, has well above average velo and has slight armside run.
