Minnesota Twins
Although they have not thrown an MLB pitch in 2024, Sean Gilmartin threw 1,834 pitches that were tracked by the PITCHf/x system between 2015 and 2020, including pitches thrown in the MLB Regular Season and the MLB Postseason. In 2020, they relied primarily on their Change using a Circle Change grip (77mph), Fourseam Fastball (87mph) and Slider (79mph), also mixing in a Sinker (87mph) and Curve (72mph).
In 2020, compared to other LHP:
Their change using a circle change grip comes in below hitting speed, has slight cut action and results in somewhat more flyballs compared to other pitchers' changeups. Their fourseam fastball comes in below hitting speed, generates an extremely high number of swings & misses compared to other pitchers' fourseamers and is an extreme flyball pitch compared to other pitchers' fourseamers. Their slider sweeps across the zone, has below average velo, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their sinker (take this with a grain of salt because they've only thrown 9 of them in 2020) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has less armside run than typical, has little sinking action compared to a true sinker and has slightly below average velo. Their curve (take this with a grain of salt because they've only thrown 8 of them in 2020) is basically never swung at and missed compared to other pitchers' curves, has sweeping glove-side movement, has below average velo and results in somewhat more flyballs compared to other pitchers' curves.
