Pittsburgh Pirates
Although they have not thrown an MLB pitch in 2025, Wei-Chieh Huang threw 1,454 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 Fourseam Fastball (92mph) and Slider (84mph), also mixing in a Sinker (94mph) and Change (84mph). He also rarely threw a Curve (76mph).
In 2023, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has less armside movement than typical, has essentially average velo and has some added backspin. Their slider (take this with a grain of salt because they've only thrown 9 of them in 2023) generates an extremely high number of swings & misses compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders, has primarily 12-6 movement and has some two-plane movement. Their sinker (take this with a grain of salt because they've only thrown 5 of them in 2023) generates an extremely high number of swings & misses compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has well above average velo, has less armside run than typical and has little sinking action compared to a true sinker. Their change (take this with a grain of salt because they've only thrown 4 of them in 2023) results in more flyballs compared to other pitchers' changeups and has a lot of backspin. Their curve (take this with a grain of salt because they've only thrown 1 of them in 2023) has an exceptional bite, is basically never swung at and missed compared to other pitchers' curves, has primarily 12-6 movement, results in more flyballs compared to other pitchers' curves and has slightly below average velo.
