Isaiah Campbell has thrown 998 pitches that have been tracked by the PITCHf/x system between 2023 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Cutter (87mph), Slider (82mph) and Fourseam Fastball (94mph). He also rarely throws a Sinker (93mph) and Change (89mph).
In 2024, compared to other RHP:
Their cutter has heavy sink, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' cutters and has strong cutting action. Their slider sweeps across the zone, has exceptional depth, is an extreme flyball pitch compared to other pitchers' sliders and has below average velo. Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has essentially average velo and has slightly less natural movement than typical. Their sinker (take this with a grain of salt because they've only thrown 17 of them in 2024) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and has slightly above average velo. Their change (take this with a grain of salt because they've only thrown 1 of them in 2024) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, results in more flyballs compared to other pitchers' changeups and has an extreme amount of backspin.
