Kumar Rocker has thrown 1,956 pitches that have been tracked by the PITCHf/x system between 2024 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (96mph) and Sinker (96mph), also mixing in a Cutter (90mph), Slider (85mph), Curve (78mph) and Change (90mph). He also rarely throws a Slow Curve (78mph).
In 2025, compared to other RHP:
Their fourseam fastball has heavy sinking action, has well above average velo and has slight armside run. Their sinker generates a very high amount of groundballs compared to other pitchers' sinkers, is blazing fast, has slight armside run and has some natural sinking action. Their cutter has heavy sink, generates a high number of swings & misses compared to other pitchers' cutters, results in more flyballs compared to other pitchers' cutters and has slightly above average velo. Their slider has exceptional depth, generates more whiffs/swing compared to other pitchers' sliders, has primarily 12-6 movement and results in somewhat more groundballs compared to other pitchers' sliders. Their curve generates an extremely high number of swings & misses compared to other pitchers' curves, has a sharp downward bite and results in somewhat more flyballs compared to other pitchers' curves. Their change is thrown extremely hard, generates fewer whiffs/swing compared to other pitchers' changeups, has slight armside fade and has some natural sink to it. Their slow curve (take this with a grain of salt because they've only thrown 2 of them in 2025) is a real yakker that's separated from their other curveball due to its big drop and slow speed.
