Pitch Repertoire At-A-Glance

Jack Leftwich has thrown 812 pitches that have been tracked by the PITCHf/x system between 2024 and 2026, including pitches thrown in the MLB Regular Season and Spring Training. In 2026, they have relied primarily on their Slider (82mph) and Fourseam Fastball (94mph), also mixing in a Sinker (93mph) and Splitter (86mph). He also rarely throws a Change (87mph).


In 2026, compared to other RHP:
Their slider sweeps across the zone, results in more flyballs compared to other pitchers' sliders, has below average velo and has some two-plane movement. Their fourseam fastball generates more whiffs/swing compared to other pitchers' fourseamers, results in more flyballs compared to other pitchers' fourseamers and has essentially average velo. Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and has some natural sinking action. Their splitter is basically never swung at and missed compared to other pitchers' splitters, has some natural sink to it and is slightly firmer than usual. Their change (take this with a grain of salt because they've only thrown 1 of them in 2026) is basically never swung at and missed compared to other pitchers' changeups, is much firmer than usual and results in more flyballs compared to other pitchers' changeups.
