St. Louis Cardinals
Kyle Leahy has thrown 3,137 pitches that have been tracked by the PITCHf/x system between 2023 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Slider (89mph) and Fourseam Fastball (95mph), also mixing in a Sinker (95mph), Change (90mph) and Curve (82mph).
In 2025, compared to other RHP:
Their slider is thrown extremely hard, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders and has short glove-side cut. Their fourseam fastball has less armside movement than typical and has slightly above average velo. Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and has well above average velo. Their change is thrown extremely hard, results in more flyballs compared to other pitchers' changeups and has some natural sink to it. Their curve (take this with a grain of salt because they've only thrown 18 of them in 2025) has an exceptional bite, is much harder than usual and results in more flyballs compared to other pitchers' curves.
