He also rarely throws a Sinker (91mph), Change (85mph) and Slider (83mph).
In 2026, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 11 of them in 2026) generates a high number of swings & misses compared to other pitchers' fourseamers, has some natural sinking action, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. Their cutter (take this with a grain of salt because they've only thrown 11 of them in 2026) is an extreme flyball pitch compared to other pitchers' cutters. Their curve (take this with a grain of salt because they've only thrown 4 of them in 2026) has an exceptional bite, is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves and has primarily 12-6 movement. Their splitter (take this with a grain of salt because they've only thrown 4 of them in 2026) generates an extremely high number of swings & misses compared to other pitchers' splitters, is an extreme flyball pitch compared to other pitchers' splitters, has some natural sink to it, is slightly firmer than usual and has slight armside fade. Their sinker (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' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and has surprisingly little armside run. 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, results in more flyballs compared to other pitchers' changeups, is slightly firmer than usual and has some natural sink to it. Their slider (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' sliders, is an extreme flyball pitch compared to other pitchers' sliders and has some two-plane movement.
