Although they have not thrown an MLB pitch in 2023, Steven Okert threw 2,473 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 Slider (82mph) and Fourseam Fastball (94mph). He also rarely threw a Change (86mph).
In 2022, compared to other LHP:
His slider sweeps across the zone and results in somewhat more flyballs compared to other pitchers' sliders. His fourseam fastball generates a very high amount of groundballs compared to other pitchers' fourseamers, has some natural sinking action and has well above average velo. His change (take this with a grain of salt because he's only thrown 1 of them in 2022) is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone, is an extreme flyball pitch compared to other pitchers' changeups, is much firmer than usual and has slight armside fade.
