Non-MLB
Shohei Ohtani has thrown 5,786 pitches that have been tracked by the PITCHf/x system between 2018 and 2023, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2023, they have relied primarily on their Slider (85mph) and Fourseam Fastball (99mph), also mixing in a Splitter (91mph) and Sinker (98mph). He also rarely throws a Curve (81mph).
In 2023, compared to other RHP:
Their slider generates an extremely high number of swings & misses compared to other pitchers' sliders, sweeps across the zone and has some two-plane movement. Their fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, is thrown at a speed that's borderline unfair, has less armside movement than typical and has some natural sinking action. Their splitter (take this with a grain of salt because they've only thrown 12 of them in 2023) is thrown extremely hard, generates a high number of swings & misses compared to other pitchers' splitters, is an extreme flyball pitch compared to other pitchers' splitters and has slight cut action. Their sinker (take this with a grain of salt because they've only thrown 8 of them in 2023) is basically never swung at and missed compared to other pitchers' sinkers, is thrown at a speed that's borderline unfair, is an extreme flyball pitch compared to other pitchers' sinkers, has slight armside run and has some natural sinking action. Their curve (take this with a grain of salt because they've only thrown 1 of them in 2023) has an exceptional bite, is basically never swung at and missed 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.
