San Diego Padres
Although they have not thrown an MLB pitch in 2024, Cha Seung Baek threw 2,675 pitches that were tracked by the PITCHf/x system between 2007 and 2008, all of them occuring in the MLB Regular Season. In 2008, they relied primarily on their Fourseam Fastball (92mph) and Cutter (86mph), also mixing in a Sinker (91mph), Curve (76mph) and Change (79mph). He also rarely threw a Slider (76mph).
In 2008, compared to other RHP:
Their fourseam fastball has essentially average velo. Their cutter has slightly below average velo and has some natural sink. Their sinker generates fewer whiffs/swing compared to other pitchers' sinkers, has less armside run than typical and results in somewhat more flyballs compared to other pitchers' sinkers. Their curve has primarily 12-6 movement, results in somewhat more flyballs compared to other pitchers' curves and has slightly below average velo. Their change has surprising cut action, has below average velo, has a lot of backspin and results in somewhat more flyballs compared to other pitchers' changeups. Their slider (take this with a grain of salt because they've only thrown 1 of them in 2008) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' sliders, has exceptional depth and is an extreme flyball pitch compared to other pitchers' sliders.
