Boston Red Sox
Chris Martin has thrown 5,237 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), also mixing in a Fourseam Fastball (95mph), Splitter (88mph) and Sinker (95mph). He also rarely throws a Slider (86mph).
In 2024, compared to other RHP:
Their cutter is blazing fast, generates a high number of swings & misses compared to other pitchers' cutters, results in somewhat more flyballs compared to other pitchers' cutters and has some natural sink. Their fourseam fastball is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action, has slight armside run and has slightly above average velo. Their splitter has dives down out of the zone, is an extreme flyball pitch compared to other pitchers' splitters and is much firmer than usual. Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, results in more flyballs 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 4 of them in 2024) is basically never swung at and missed compared to other pitchers' sliders, sweeps across the zone and results in more flyballs compared to other pitchers' sliders.
