Boston Red Sox
Although they have not thrown an MLB pitch in 2024, Liam Hendriks threw 11,241 pitches that were tracked by the PITCHf/x system between 2011 and 2023, including pitches thrown in the MLB Regular Season and Spring Training. In 2023, they relied primarily on their Fourseam Fastball (95mph) and Slider (87mph). He also rarely threw a Curve (83mph) and Change using a Circle Change grip (90mph).
In 2023, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, results in somewhat more groundballs compared to other pitchers' fourseamers, has slightly above average velo and has slightly less natural movement than typical. Their slider generates more whiffs/swing compared to other pitchers' sliders and is much harder than usual. Their curve (take this with a grain of salt because they've only thrown 8 of them in 2023) has primarily 12-6 movement, generates more whiffs/swing compared to other pitchers' curves, is much harder than usual, results in more flyballs compared to other pitchers' curves and has a sharp downward bite. Their change using a circle change grip (take this with a grain of salt because they've only thrown 1 of them in 2023) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups and results in more flyballs compared to other pitchers' changeups.
