In 2025, compared to other RHP:
Their fourseam fastball has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. Their slider sweeps across the zone and results in more flyballs compared to other pitchers' sliders. Their splitter has some natural sink to it and results in somewhat more flyballs compared to other pitchers' splitters. Their cutter results in somewhat more flyballs compared to other pitchers' cutters. Their curve generates a high number of swings & misses compared to other pitchers' curves, has a sharp downward bite, results in somewhat more flyballs compared to other pitchers' curves and has slight glove-side movement. Their sinker generates a very high amount of groundballs compared to other pitchers' sinkers and generates more whiffs/swing compared to other pitchers' sinkers. Their change (take this with a grain of salt because they've only thrown 4 of them in 2025) 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 slight armside fade.
