Although he has not thrown an MLB pitch in 2019, Joe Musgrove threw 4,500 pitches that were tracked by the PITCHf/x system between 2016 and 2018, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2018, he relied primarily on his Fourseam Fastball (94mph) and Slider (84mph), also mixing in a Sinker (93mph), Cutter (90mph) and Change (86mph). He also rarely threw a Curve (81mph).
Basic description of 2018 pitches compared to other RHP:
His fourseam fastball has less armside movement than typical, has some natural sinking action and has essentially average velo. His slider has short glove-side cut, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. His sinker generates a very high amount of groundballs compared to other pitchers' sinkers, has surprisingly little armside run and has some natural sinking action. His cutter generates fewer whiffs/swing compared to other pitchers' cutters, has slightly above average velo, has some natural sink and has strong cutting action. His change generates a high number of swings & misses compared to other pitchers' changeups, has slight cut action, is slightly firmer than usual and has some natural sink to it. His curve (take this with a grain of salt because he's only thrown 8 of them in 2018) generates an extremely high number of swings & misses compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has a sharp downward bite and is slightly harder than usual.
