Washington Nationals
Although they have not thrown an MLB pitch in 2024, T.J. Zeuch threw 2,660 pitches that were tracked by the PITCHf/x system between 2019 and 2023, including pitches thrown in the MLB Regular Season and Spring Training. In 2023, they relied primarily on their Sinker (91mph) and Slider (80mph), also mixing in a Change (85mph). He also rarely threw a Fourseam Fastball (91mph), Cutter (88mph) and Curve (77mph).
In 2023, compared to other RHP:
Their sinker has heavy sinking action and has slight armside run. Their slider comes in below hitting speed, sweeps across the zone and results in more flyballs compared to other pitchers' sliders. Their change is slightly firmer than usual, has slight armside fade and has some natural sink to it. Their fourseam fastball has heavy sinking action and has slightly below average velo. Their cutter is a real worm killer that generates an extreme number of groundballs compared to other pitchers' cutters, is basically never swung at and missed compared to other pitchers' cutters, has surprisingly little cutting action and has some natural sink. Their curve (take this with a grain of salt because they've only thrown 1 of them in 2023) is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has little depth and has slight glove-side movement.
