Non-MLB
Although they have not thrown an MLB pitch in 2024, Casey Janssen threw 6,542 pitches that were tracked by the PITCHf/x system between 2007 and 2015, all of them occuring in the MLB Regular Season. In 2015, they relied primarily on their Fourseam Fastball (89mph) and Cutter (88mph), also mixing in a Curve (74mph) and Slider (84mph). He also rarely threw a Change (82mph).
In 2015, compared to other RHP:
Their fourseam fastball comes in below hitting speed, generates fewer whiffs/swing compared to other pitchers' fourseamers, has less armside movement than typical, has some natural sinking action and results in somewhat more flyballs compared to other pitchers' fourseamers. Their cutter has good "rise" and results in somewhat more flyballs compared to other pitchers' cutters. Their curve has sweeping glove-side movement, has below average velo and results in somewhat more flyballs compared to other pitchers' curves. Their slider is basically never swung at and missed compared to other pitchers' sliders and has less than expected depth. Their change (take this with a grain of salt because they've only thrown 14 of them in 2015) generates fewer whiffs/swing compared to other pitchers' changeups, has slight cut action and has slightly below average velo.
