Ian Seymour has thrown 3,874 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 Change (84mph), Slider (82mph) and Fourseam Fastball (92mph), also mixing in a Sinker (90mph) and Cutter (87mph). He also rarely throws a Curve (72mph).
In 2026, compared to other LHP:
Their change is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups, generates a high number of swings & misses compared to other pitchers' changeups, has slight armside fade and has some natural sink to it. Their slider sweeps across the zone, has less than expected depth and results in somewhat more flyballs compared to other pitchers' sliders. Their fourseam fastball has essentially average velo, results in somewhat more flyballs compared to other pitchers' fourseamers and has slightly less natural movement than typical. Their sinker generates fewer whiffs/swing compared to other pitchers' sinkers, results in somewhat more flyballs compared to other pitchers' sinkers and has some natural sinking action. Their cutter generates a high number of swings & misses compared to other pitchers' cutters, has slightly above average velo and has strong cutting action. Their curve (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' curves, is an extreme flyball pitch compared to other pitchers' curves, has below average velo, has a sharp downward bite and has slight glove-side movement.
