Boston Red Sox
Koji Uehara has thrown 6,258 pitches that have been tracked by the PITCHf/x system between 2009 and 2016, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2016, he has relied primarily on his Splitter (79mph) and Fourseam Fastball (87mph), also mixing in a Cutter (83mph).
Basic description of 2016 pitches compared to other RHP:
His splitter comes in below hitting speed and has slight armside fade. His fourseam fastball comes in below hitting speed, generates more whiffs/swing compared to other pitchers' fourseamers, results in somewhat more groundballs compared to other pitchers' fourseamers, has slight armside run and has some added backspin. His cutter (take this with a grain of salt because he's only thrown 12 of them in 2016) comes in below hitting speed, generates an extremely high number of swings & misses compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has good "rise".
