Although they have not thrown an MLB pitch in 2023, Marcus Stroman threw 19,059 pitches that were tracked by the PITCHf/x system between 2013 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they relied primarily on their Sinker (92mph) and Slider (85mph), also mixing in a Change (87mph), Cutter (90mph) and Fourseam Fastball (93mph). He also rarely threw a Curve (82mph).
In 2022, compared to other RHP:
His sinker has heavy sinking action and has surprisingly little armside run. His slider sweeps across the zone, generates a very high amount of groundballs compared to other pitchers' sliders and has some two-plane movement. His change dives down out of the zone and is much firmer than usual. His cutter has heavy sink, results in many more groundballs compared to other pitchers' cutters and has slightly above average velo. His fourseam fastball generates more whiffs/swing compared to other pitchers' fourseamers, has less armside movement than typical, has some natural sinking action, has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. His curve (take this with a grain of salt because he's only thrown 16 of them in 2022) is basically never swung at and missed compared to other pitchers' curves, has sweeping glove-side movement, is much harder than usual and results in more flyballs compared to other pitchers' curves.
