Philadelphia Phillies
Although they have not thrown an MLB pitch in 2024, Chris Bootcheck threw 1,440 pitches that were tracked by the PITCHf/x system between 2007 and 2013, including pitches thrown in the MLB Regular Season and Spring Training. In 2013, they relied primarily on their Fourseam Fastball (90mph), also mixing in a Slider (85mph) and Curve (83mph). He also rarely threw a Change (78mph).
In 2013, compared to other RHP:
Their fourseam fastball is basically never swung at and missed compared to other pitchers' fourseamers, is straight as an arrow, is an extreme flyball pitch compared to other pitchers' fourseamers, has below average velo and has some natural sinking action. Their slider (take this with a grain of salt because they've only thrown 6 of them in 2013) is an extreme flyball pitch compared to other pitchers' sliders. Their curve (take this with a grain of salt because they've only thrown 2 of them in 2013) is basically never swung at and missed compared to other pitchers' curves, has primarily 12-6 movement, is much harder than usual, results in more flyballs compared to other pitchers' curves and has little depth. Their change (take this with a grain of salt because they've only thrown 1 of them in 2013) comes in below hitting speed, 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 a lot of backspin.
