St. Louis Cardinals
Ryan Helsley has thrown 3,763 pitches that have been tracked by the PITCHf/x system between 2019 and 2024, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2024, they have relied primarily on their Slider (89mph) and Fourseam Fastball (99mph), also mixing in a Curve (80mph).
In 2024, compared to other RHP:
Their slider is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders and has some two-plane movement. Their fourseam fastball is thrown at a speed that's borderline unfair, has less armside movement than typical and results in somewhat more groundballs compared to other pitchers' fourseamers. Their curve (take this with a grain of salt because they've only thrown 17 of them in 2024) generates an extremely high number of swings & misses compared to other pitchers' curves, has primarily 12-6 movement and results in more flyballs compared to other pitchers' curves.
