St. Louis Cardinals
Although they have not thrown an MLB pitch in 2023, Miles Mikolas threw 11,714 pitches that were tracked by the PITCHf/x system between 2012 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they relied primarily on their Fourseam Fastball (94mph), Slider (88mph), Sinker (93mph) and Curve (76mph). He also rarely threw a Change (83mph) and Slow Curve (65mph).
In 2022, compared to other RHP:
His fourseam fastball has some natural sinking action, has essentially average velo and has slightly less natural movement than typical. His slider generates fewer whiffs/swing compared to other pitchers' sliders and is much harder than usual. His sinker is a prototypical pitch with few remarkable qualities. His curve has an exceptional bite, generates fewer whiffs/swing compared to other pitchers' curves and has slightly below average velo. His change is basically never swung at and missed compared to other pitchers' changeups and results in somewhat more flyballs compared to other pitchers' changeups. His slow curve (take this with a grain of salt because he's only thrown 11 of them in 2022) is a real yakker that's separated from his other curveball due to its big drop and slow speed.
