Geoff Hartlieb has thrown 3,849 pitches that have been tracked by the PITCHf/x system between 2019 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Slider (85mph) and Fourseam Fastball (95mph), also mixing in a Sinker (93mph). He also rarely throws a Change (87mph) and Cutter (88mph).
In 2025, compared to other RHP:
Their slider generates an extremely high number of swings & misses compared to other pitchers' sliders, has primarily 12-6 movement and has some two-plane movement. Their fourseam fastball generates fewer whiffs/swing compared to other pitchers' fourseamers, has some natural sinking action and has slightly above average velo. Their sinker has slight armside run, has slightly above average velo and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 2 of them in 2025) is basically never swung at and missed compared to other pitchers' changeups, is much firmer than usual, results in more flyballs compared to other pitchers' changeups and has some natural sink to it. Their cutter (take this with a grain of salt because they've only thrown 1 of them in 2025) explodes on the hitter, is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has little cutting action.
