Non-MLB
Although they have not thrown an MLB pitch in 2024, Carlos Martinez threw 16,124 pitches that were tracked by the PITCHf/x system between 2013 and 2023, including pitches thrown in the MLB Regular Season, the MLB Postseason, Spring Training and Fall/Winter Ball. In 2023, they relied primarily on their Sinker (89mph), Cutter (89mph), Slider (81mph) and Fourseam Fastball (91mph), also mixing in a Change (82mph).
In 2023, compared to other RHP:
Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, has heavy sinking action, has below average velo, results in more flyballs compared to other pitchers' sinkers and has slight armside run. Their cutter has little cutting action and has some natural sink. Their slider 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, has below average velo and has some two-plane movement. Their fourseam fastball has heavy sinking action, results in somewhat more groundballs compared to other pitchers' fourseamers, has slight armside run and has slightly below average velo. Their change (take this with a grain of salt because they've only thrown 14 of them in 2023) generates fewer whiffs/swing compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, has slightly below average velo and has some natural sink to it.
