Non-MLB
Although they have not thrown an MLB pitch in 2024, Aaron Crow threw 4,130 pitches that were tracked by the PITCHf/x system between 2010 and 2014, including pitches thrown in the MLB Regular Season and Spring Training. In 2014, they relied primarily on their Sinker (93mph) and Slider (83mph), also mixing in a Fourseam Fastball (93mph). He also rarely threw a Change using a Circle Change grip (86mph).
In 2014, compared to other RHP:
Their sinker generates fewer whiffs/swing compared to other pitchers' sinkers and has slight armside run. Their slider has exceptional depth and is an extreme flyball pitch compared to other pitchers' sliders. Their fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, generates fewer whiffs/swing compared to other pitchers' fourseamers, has essentially average velo and has slight armside run. Their change using a circle change grip (take this with a grain of salt because they've only thrown 4 of them in 2014) is basically never swung at and missed compared to other pitchers' changeups, has an obvious armside fade, results in more flyballs compared to other pitchers' changeups, is slightly firmer than usual and has some natural sink to it.
