Although they have not thrown an MLB pitch in 2023, Nick Maton threw 29 pitches that were tracked by the PITCHf/x system between 2021 and 2022, all of them occuring in the MLB Regular Season. In 2022, they relied primarily on their Fourseam Fastball (80mph), also mixing in a Curve (51mph).
In 2022, compared to other RHP:
Their fourseam fastball comes in below hitting speed, has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, results in somewhat more groundballs compared to other pitchers' fourseamers and has slight armside run. Their curve (take this with a grain of salt because they've only thrown 3 of them in 2022) comes in below hitting speed, has very little depth, is basically never swung at and missed compared to other pitchers' curves, has primarily 12-6 movement and results in more flyballs compared to other pitchers' curves.
