Toronto Blue Jays
Although they have not thrown an MLB pitch in 2023, Kevin Gausman threw 22,892 pitches that were tracked by the PITCHf/x system between 2013 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they relied primarily on their Fourseam Fastball (95mph) and Splitter (85mph), also mixing in a Slider (84mph). He also rarely threw a Change using a Circle Change grip (85mph).
In 2022, compared to other RHP:
His fourseam fastball has slight armside run and has slightly above average velo. His splitter generates a high number of swings & misses compared to other pitchers' splitters, has some natural sink to it and has slight armside fade. His slider has primarily 12-6 movement and results in somewhat more flyballs compared to other pitchers' sliders. His change using a circle change grip (take this with a grain of salt because he's only thrown 14 of them in 2022) generates an extremely high number of swings & misses compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, has a lot of backspin and is slightly firmer than usual.
