Boston Red Sox
Although they have not thrown an MLB pitch in 2024, Carlos Marmol threw 9,101 pitches that were tracked by the PITCHf/x system between 2007 and 2014, including pitches thrown in the MLB Regular Season and Spring Training. In 2014, they relied primarily on their Slider (85mph) and Fourseam Fastball (95mph). He also rarely threw a Sinker (94mph).
In 2014, compared to other RHP:
Their slider is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, has exceptional depth and has short glove-side cut. Their fourseam fastball has some natural sinking action, results in somewhat more flyballs compared to other pitchers' fourseamers, has slightly above average velo and has slightly less natural movement than typical. Their sinker (take this with a grain of salt because they've only thrown 1 of them in 2014) has heavy sinking action, is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and has well above average velo.
