Trent Thornton has thrown 7,144 pitches that have been tracked by the PITCHf/x system between 2017 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (95mph), Cutter (90mph) and Slider (81mph), also mixing in a Curve (82mph) and Sinker (94mph). He also rarely throws a Splitter (87mph).
In 2025, compared to other RHP:
Their fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, has less armside movement than typical and has slightly above average velo. Their cutter generates an extremely high number of swings & misses compared to other pitchers' cutters, has heavy sink, results in more flyballs compared to other pitchers' cutters and has strong cutting action. Their slider sweeps across the zone, generates fewer whiffs/swing compared to other pitchers' sliders, has below average velo and has some two-plane movement. Their curve is much harder than usual, has a sharp downward bite and results in somewhat more flyballs compared to other pitchers' curves. Their sinker (take this with a grain of salt because they've only thrown 17 of them in 2025) generates an extremely high number of swings & misses compared to other pitchers' sinkers, results in more flyballs compared to other pitchers' sinkers, has well above average velo, has less armside run than typical and has some natural sinking action. Their splitter (take this with a grain of salt because they've only thrown 12 of them in 2025) is much firmer than usual, results in more flyballs compared to other pitchers' splitters and has some natural sink to it.
