Miami Marlins
Michael Petersen has thrown 2,084 pitches that have been tracked by the PITCHf/x system between 2023 and 2025, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (97mph) and Slider (89mph). He also rarely throws a Sinker (98mph) and Change (89mph).
In 2025, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is blazing fast and results in somewhat more flyballs compared to other pitchers' fourseamers. Their slider is thrown extremely hard, has primarily 12-6 movement and results in somewhat more groundballs compared to other pitchers' sliders. Their sinker (take this with a grain of salt because they've only thrown 15 of them in 2025) generates an extremely high number of swings & misses compared to other pitchers' sinkers, is thrown at a speed that's borderline unfair, results in more flyballs compared to other pitchers' sinkers and has little sinking action compared to a true sinker. Their change (take this with a grain of salt because they've only thrown 11 of them in 2025) is thrown extremely hard, generates fewer whiffs/swing compared to other pitchers' changeups and results in more flyballs compared to other pitchers' changeups.
