Justin Dunn has thrown 1,369 pitches that have been tracked by the PITCHf/x system between 2019 and 2021, all of them occuring in the MLB Regular Season. In 2021, he has relied primarily on his Fourseam Fastball (94mph) and Curve (80mph), also mixing in a Slider (84mph). He also rarely throws a Change (89mph).
In 2021, compared to other RHP:
His fourseam fastball generates more whiffs/swing compared to other pitchers' fourseamers, has essentially average velo, results in somewhat more flyballs compared to other pitchers' fourseamers and has slight armside run. His curve has very little depth, has sweeping glove-side movement, is slightly harder than usual and results in somewhat more flyballs compared to other pitchers' curves. His slider has exceptional depth, generates fewer whiffs/swing compared to other pitchers' sliders and has short glove-side cut. His change (take this with a grain of salt because he's only thrown 3 of them in 2021) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, has a lot of backspin and has slight armside fade.
