Boston Red Sox
Although they have not thrown an MLB pitch in 2024, Michael Fulmer threw 11,142 pitches that were tracked by the PITCHf/x system between 2016 and 2023, including pitches thrown in the MLB Regular Season and Spring Training. In 2023, they relied primarily on their Slider (86mph) and Fourseam Fastball (94mph), also mixing in a Sinker (95mph) and Change (90mph).
In 2023, compared to other RHP:
Their slider (take this with a grain of salt because they've only thrown 8 of them in 2023) generates an extremely high number of swings & misses compared to other pitchers' sliders, sweeps across the zone and is an extreme flyball pitch compared to other pitchers' sliders. Their fourseam fastball (take this with a grain of salt because they've only thrown 2 of them in 2023) generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is straight as an arrow, is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action and has essentially average velo. Their sinker (take this with a grain of salt because they've only thrown 2 of them in 2023) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and is blazing fast.
