Red Sox trade deadline addition ‘bumped up’ velocity, sinker up to 96.5 mph
Quinn Priester’s fastball averaged 93.0 mph in 44 ⅔ innings with the Pirates this season, putting him in the 33rd percentile in fastball velocity among major league pitchers. The Red Sox knew the 24-year-old righty had the ability to throw harder when they acquired him in a 1-for-1 swap of former first-rounders that sent Nick Yorke to Pittsburgh on July 29.
