Michael Fulmer has thrown 7,921 pitches that have been tracked by the PITCHf/x system between 2016 and 2021, all of them occuring in the MLB Regular Season. In 2021, he has relied primarily on his Slider (90mph), Sinker (96mph) and Fourseam Fastball (95mph), also mixing in a Change (88mph). He also rarely throws a Curve (80mph).
In 2021, compared to other RHP:
His slider is thrown extremely hard. His sinker generates a high number of swings & misses compared to other pitchers' sinkers and is blazing fast. His fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has much less armside movement than typical and has slightly above average velo. His change is much firmer than usual and has some natural sink to it. His curve (take this with a grain of salt because he's only thrown 15 of them in 2021) has sweeping glove-side movement, results in more flyballs compared to other pitchers' curves and is slightly harder than usual.
