Boston Red Sox
Nick Burdi has thrown 1,737 pitches that have been tracked by the PITCHf/x system between 2018 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Sinker (94mph), Slider (86mph) and Fourseam Fastball (96mph). He also rarely throws a Change (89mph).
In 2025, compared to other RHP:
Their sinker has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers, has slight armside run and has slightly above average velo. Their slider sweeps across the zone, results in many more groundballs compared to other pitchers' sliders and has some two-plane movement. Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has heavy sinking action, results in more flyballs compared to other pitchers' fourseamers, has well above average velo and has slight armside run. Their change (take this with a grain of salt because they've only thrown 15 of them in 2025) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone, results in more flyballs compared to other pitchers' changeups and has slight armside fade.
