Pitch Repertoire At-A-Glance

Mason Thompson has thrown 793 pitches that have been tracked by the PITCHf/x system between 2021 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they have relied primarily on their Sinker (96mph) and Slider (85mph). He also rarely throws a Fourseam Fastball (96mph) and Change (88mph).


In 2022, compared to other RHP:
His sinker is blazing fast and has slight armside run. His slider generates an extremely high number of swings & misses compared to other pitchers' sliders and has exceptional depth. His fourseam fastball (take this with a grain of salt because he's only thrown 7 of them in 2022) generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers and has well above average velo. His change (take this with a grain of salt because he's only thrown 3 of them in 2022) is basically never swung at and missed compared to other pitchers' changeups, has an obvious armside fade, is much firmer than usual, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
