Their sinker results in somewhat more flyballs compared to other pitchers' sinkers, has slight armside run and has slightly above average velo. Their fourseam fastball (take this with a grain of salt because they've only thrown 17 of them in 2026) generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers and has essentially average velo. Their slider (take this with a grain of salt because they've only thrown 17 of them in 2026) sweeps across the zone, is an extreme flyball pitch compared to other pitchers' sliders, has below average velo and has some two-plane movement. Their cutter (take this with a grain of salt because they've only thrown 14 of them in 2026) has heavy sink, is basically never swung at and missed compared to other pitchers' cutters and is an extreme flyball pitch compared to other pitchers' cutters. Their change (take this with a grain of salt because they've only thrown 8 of them in 2026) is thrown extremely hard, generates fewer whiffs/swing compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has some natural sink to it. Their curve (take this with a grain of salt because they've only thrown 2 of them in 2026) generates an extremely high number of swings & misses compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves and has slight glove-side movement.
