Chicago White Sox
Michael Kopech has thrown 6,106 pitches that have been tracked by the PITCHf/x system between 2018 and 2024, all of them occuring in the MLB Regular Season. In 2024, they have relied primarily on their Fourseam Fastball (99mph), also mixing in a Slider (86mph). He also rarely throws a Curve (85mph) and Cutter (94mph).
In 2024, compared to other RHP:
Their fourseam fastball is thrown at a speed that's borderline unfair and generates a high number of swings & misses compared to other pitchers' fourseamers. Their slider generates an extremely high number of swings & misses compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders, has short glove-side cut and has some two-plane movement. Their curve (take this with a grain of salt because they've only thrown 8 of them in 2024) is thrown extremely hard, has primarily 12-6 movement and results in somewhat more flyballs compared to other pitchers' curves. Their cutter (take this with a grain of salt because they've only thrown 2 of them in 2024) is thrown at a speed that's borderline unfair, is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has strong cutting action.
