Kansas City Royals
Although they have not thrown an MLB pitch in 2023, Daniel Mengden threw 5,150 pitches that were tracked by the PITCHf/x system between 2016 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they relied primarily on their Cutter (88mph) and Fourseam Fastball (92mph), also mixing in a Change (84mph) and Curve (72mph). He also rarely threw a Slider (83mph).
In 2022, compared to other RHP:
His cutter results in somewhat more flyballs compared to other pitchers' cutters, has some natural sink and has strong cutting action. His fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has essentially average velo and has slightly less natural movement than typical. His change is basically never swung at and missed compared to other pitchers' changeups and has some natural sink to it. His curve comes in below hitting speed, generates fewer whiffs/swing compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has a sharp downward bite and has slight glove-side movement. His slider (take this with a grain of salt because he's only thrown 4 of them in 2022) is basically never swung at and missed compared to other pitchers' sliders, has exceptional depth and is an extreme flyball pitch compared to other pitchers' sliders.
