Kansas City Royals
Although they have not thrown an MLB pitch in 2024, Zack Greinke threw 49,491 pitches that were tracked by the PITCHf/x system between 2007 and 2023, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2023, they relied primarily on their Fourseam Fastball (90mph) and Slider (79mph), also mixing in a Change (87mph), Sinker (90mph), Curve (73mph) and Cutter (86mph). He also rarely threw a Slow Curve (58mph).
In 2023, compared to other RHP:
Their fourseam fastball has much less armside movement than typical, has below average velo, has some natural sinking action and results in somewhat more flyballs compared to other pitchers' fourseamers. Their slider comes in below hitting speed, sweeps across the zone, generates fewer whiffs/swing compared to other pitchers' sliders, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their change generates a very high amount of groundballs compared to other pitchers' changeups, generates fewer whiffs/swing compared to other pitchers' changeups, is slightly firmer than usual and has some natural sink to it. Their sinker generates fewer whiffs/swing compared to other pitchers' sinkers and has slightly below average velo. Their curve comes in below hitting speed, is basically never swung at and missed compared to other pitchers' curves, has a sharp downward bite, results in somewhat more flyballs compared to other pitchers' curves and has slight glove-side movement. Their cutter has heavy sink, has sweeping cut action, has below average velo and results in more flyballs compared to other pitchers' cutters. Their slow curve (take this with a grain of salt because they've only thrown 1 of them in 2023) is a real yakker that's separated from their other curveball due to its big drop and slow speed.
