Boston Red Sox
John Brebbia has thrown 7,078 pitches that have been tracked by the PITCHf/x system between 2017 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (93mph) and Slider (84mph), also mixing in a Change (86mph). He also rarely throws a Curve (72mph).
In 2025, compared to other RHP:
Their fourseam fastball has essentially average velo and has slight armside run. Their slider results in more flyballs compared to other pitchers' sliders and has short glove-side cut. Their change is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups, is basically never swung at and missed compared to other pitchers' changeups, is slightly firmer than usual, has slight armside fade and has some natural sink to it. Their curve (take this with a grain of salt because they've only thrown 14 of them in 2025) comes in below hitting speed, generates an extremely high number of swings & misses compared to other pitchers' curves and results in more flyballs compared to other pitchers' curves.
