Pittsburgh Pirates
Joe La Sorsa has thrown 3,431 pitches that have been tracked by the PITCHf/x system between 2023 and 2026, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2026, they have relied primarily on their Slider (79mph) and Sinker (91mph), also mixing in a Fourseam Fastball (93mph) and Change (84mph).
In 2026, compared to other LHP:
Their slider generates an extremely high number of swings & misses compared to other pitchers' sliders, sweeps across the zone, results in more flyballs compared to other pitchers' sliders, has below average velo and has some two-plane movement. Their sinker has slight armside run and has some natural sinking action. Their fourseam fastball (take this with a grain of salt because they've only thrown 18 of them in 2026) has heavy sinking action, generates fewer whiffs/swing compared to other pitchers' fourseamers, results in somewhat more groundballs compared to other pitchers' fourseamers, has slight armside run and has slightly above average velo. Their change (take this with a grain of salt because they've only thrown 14 of them in 2026) is basically never swung at and missed compared to other pitchers' changeups, is an extreme flyball pitch compared to other pitchers' changeups, is slightly firmer than usual and has some natural sink to it.
