Chicago Cubs
Justin Steele has thrown 5,741 pitches that have been tracked by the PITCHf/x system between 2021 and 2024, all of them occuring in the MLB Regular Season. In 2024, they have relied primarily on their Cutter (92mph) and Slider (83mph).
In 2024, compared to other LHP:
Their cutter is thrown at a speed that's borderline unfair, results in more flyballs compared to other pitchers' cutters and has strong cutting action. Their slider (take this with a grain of salt because they've only thrown 18 of them in 2024) sweeps across the zone and has some two-plane movement.
