Jack Mayfield

Non-MLB

Pitch Repertoire At-A-Glance

Although they have not thrown an MLB pitch in 2023, Jack Mayfield threw 16 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 Knuckleball (60mph) and Fourseam Fastball (65mph), also mixing in a Change (56mph).


In 2022, compared to other RHP:
His knuckleball (take this with a grain of salt because he's only thrown 7 of them in 2022) flutters and floats unpredictably toward the plate. His fourseam fastball (take this with a grain of salt because he's only thrown 4 of them in 2022) comes in below hitting speed, has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers and has slight armside run. His change (take this with a grain of salt because he's only thrown 2 of them in 2022) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, results in more flyballs compared to other pitchers' changeups and has a lot of backspin.
