Josh Simpson has thrown 2,419 pitches that have been tracked by the PITCHf/x system between 2021 and 2026, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2026, they have relied primarily on their Curve (79mph) and Fourseam Fastball (94mph), also mixing in a Sinker (93mph), Change (88mph) and Slider (80mph).
In 2026, compared to other LHP:
Their curve generates fewer whiffs/swing compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, is slightly harder than usual and has slight glove-side movement. Their fourseam fastball has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, has well above average velo, results in somewhat more flyballs compared to other pitchers' fourseamers and has slightly less natural movement than typical. Their sinker (take this with a grain of salt because they've only thrown 18 of them in 2026) generates an extremely high number of swings & misses compared to other pitchers' sinkers, has heavy sinking action, is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run and has slightly above average velo. Their change (take this with a grain of salt because they've only thrown 13 of them in 2026) is thrown extremely hard, dives down out of the zone and is an extreme flyball pitch compared to other pitchers' changeups. Their slider (take this with a grain of salt because they've only thrown 13 of them in 2026) sweeps across the zone, generates fewer whiffs/swing compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders and has some two-plane movement.
