Jonathan Bowlan has thrown 3,704 pitches that have been tracked by the PITCHf/x system between 2023 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (96mph) and Slider (86mph), also mixing in a Sinker (96mph) and Change (89mph). He also rarely throws a Curve (82mph).
In 2025, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has well above average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. Their slider is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, has exceptional depth and generates more whiffs/swing compared to other pitchers' sliders. Their sinker is blazing fast and results in somewhat more flyballs compared to other pitchers' sinkers. Their change is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has some natural sink to it. Their curve (take this with a grain of salt because they've only thrown 17 of them in 2025) generates more whiffs/swing compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, is slightly harder than usual and has slight glove-side movement.
