Miami Marlins
Michael Petersen has thrown 1,341 pitches that have been tracked by the PITCHf/x system between 2023 and 2024, including pitches thrown in the MLB Regular Season and The World Baseball Classic. In 2024, they have relied primarily on their Fourseam Fastball (98mph) and Slider (88mph). He also rarely throws a Change (90mph) and Sinker (97mph).
In 2024, compared to other RHP:
Their fourseam fastball is blazing fast, generates more whiffs/swing compared to other pitchers' fourseamers and results in more flyballs compared to other pitchers' fourseamers. Their slider is much harder than usual, has primarily 12-6 movement, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their change is thrown extremely hard and results in more flyballs compared to other pitchers' changeups. Their sinker is thrown at a speed that's borderline unfair, generates fewer whiffs/swing compared to other pitchers' sinkers, has less armside run than typical and has little sinking action compared to a true sinker.
