St. Louis Cardinals
Ryan Helsley has thrown 3,845 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 Fourseam Fastball (99mph) and Slider (89mph), also mixing in a Curve (80mph).
In 2024, compared to other RHP:
Their fourseam fastball is blazing fast, has less armside movement than typical and results in somewhat more flyballs compared to other pitchers' fourseamers. Their slider is an extreme flyball pitch compared to other pitchers' sliders, is much harder than usual and has some two-plane movement. Their curve (take this with a grain of salt because they've only thrown 10 of them in 2024) generates an extremely high number of swings & misses compared to other pitchers' curves, has primarily 12-6 movement, results in more flyballs compared to other pitchers' curves and is slightly harder than usual.
