Boston Red Sox
Chris Martin has thrown 5,503 pitches that have been tracked by the PITCHf/x system between 2014 and 2024, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2024, they have relied primarily on their Cutter (92mph) and Fourseam Fastball (95mph), also mixing in a Splitter (88mph) and Sinker (95mph). He also rarely throws a Slider (85mph).
In 2024, compared to other RHP:
Their cutter is blazing fast, is an extreme flyball pitch compared to other pitchers' cutters, generates more whiffs/swing compared to other pitchers' cutters and has some natural sink. Their fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, generates more whiffs/swing compared to other pitchers' fourseamers, has some natural sinking action and has slightly above average velo. Their splitter is thrown extremely hard, is an extreme flyball pitch compared to other pitchers' splitters and has some natural sink to it. Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, has well above average velo and has slight armside run. Their slider (take this with a grain of salt because they've only thrown 9 of them in 2024) is basically never swung at and missed compared to other pitchers' sliders, sweeps across the zone, results in many more groundballs compared to other pitchers' sliders and has some two-plane movement.
