Chicago Cubs
Justin Steele has thrown 8,129 pitches that have been tracked by the PITCHf/x system between 2021 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Cutter (91mph) and Slider (82mph), also mixing in a Sinker (91mph). He also rarely throws a Curve (80mph) and Change (86mph).
In 2025, compared to other LHP:
Their cutter is thrown at a speed that's borderline unfair and explodes on the hitter. Their slider sweeps across the zone, has exceptional depth and results in somewhat more flyballs compared to other pitchers' sliders. Their sinker is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run and has some natural sinking action. Their curve (take this with a grain of salt because they've only thrown 12 of them in 2025) is basically never swung at and missed compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves, is much harder than usual and has slight glove-side movement. Their change (take this with a grain of salt because they've only thrown 11 of them in 2025) is basically never swung at and missed compared to other pitchers' changeups, is much firmer than usual, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
