Cleveland Guardians
Although they have not thrown an MLB pitch in 2023, Zach Plesac threw 7,103 pitches that were tracked by the PITCHf/x system between 2019 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they relied primarily on their Fourseam Fastball (92mph), Slider (86mph) and Change (86mph), also mixing in a Curve (80mph). He also rarely threw a Sinker (90mph).
In 2022, compared to other RHP:
His fourseam fastball has essentially average velo and has some added backspin. His slider results in many more groundballs compared to other pitchers' sliders, has less than expected depth and has primarily 12-6 movement. His change generates fewer whiffs/swing compared to other pitchers' changeups, has a lot of backspin, is slightly firmer than usual and results in somewhat more flyballs compared to other pitchers' changeups. His curve has primarily 12-6 movement. His sinker (take this with a grain of salt because he's only thrown 3 of them in 2022) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has little sinking action compared to a true sinker and has slightly below average velo.
