Trent Thornton has thrown 7,192 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, has some natural sinking action 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 somewhat more flyballs compared to other pitchers' cutters, has slightly above average velo 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 has a sharp downward bite and is slightly harder than usual. 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 15 of them in 2025) is an extreme flyball pitch compared to other pitchers' splitters, is much firmer than usual and has some natural sink to it.
