Boston Red Sox
Matt Barnes has thrown 5,420 pitches that have been tracked by the PITCHf/x system between 2012 and 2019, including pitches thrown in the MLB Regular Season and the MLB Postseason. In 2019, he has relied primarily on his Curve (86mph) and Fourseam Fastball (97mph). He also rarely throws a Change (88mph).
Basic description of 2019 pitches compared to other RHP:
His curve is thrown extremely hard, has primarily 12-6 movement, generates more whiffs/swing compared to other pitchers' curves, results in many more groundballs compared to other pitchers' curves and has a sharp downward bite. His fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is blazing fast and has slight armside run. His change (take this with a grain of salt because he's only thrown 14 of them in 2019) generates an extremely high number of swings & misses compared to other pitchers' changeups, is much firmer than usual, results in more flyballs compared to other pitchers' changeups and has a lot of backspin.
