Nick Wittgren has thrown 7,202 pitches that have been tracked by the PITCHf/x system between 2016 and 2025, including pitches thrown in the MLB Regular Season, The World Baseball Classic, Spring Training and Fall/Winter Ball. In 2025, they have relied primarily on their Fourseam Fastball (91mph) and Slider (82mph), also mixing in a Cutter (88mph), Sinker (91mph) and Change (84mph).
In 2025, compared to other RHP:
Their fourseam fastball is basically never swung at and missed compared to other pitchers' fourseamers, has some natural sinking action, results in somewhat more groundballs compared to other pitchers' fourseamers and has slightly below average velo. Their slider (take this with a grain of salt because they've only thrown 14 of them in 2025) generates an extremely high number of swings & misses compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders and has short glove-side cut. Their cutter (take this with a grain of salt because they've only thrown 11 of them in 2025) is an extreme flyball pitch compared to other pitchers' cutters, generates fewer whiffs/swing compared to other pitchers' cutters, has some natural sink and has strong cutting action. Their sinker (take this with a grain of salt because they've only thrown 7 of them in 2025) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has slightly below average velo and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 5 of them in 2025) dives down out of the zone and results in more flyballs compared to other pitchers' changeups.
