Branden Kline has thrown 283 pitches that have been tracked by the PITCHf/x system between 2013 and 2019, including pitches thrown in the MLB Regular Season and Fall/Winter Ball. In 2019, he has relied primarily on his Fourseam Fastball (97mph) and Slider (87mph). He also rarely throws a Change (87mph).
Basic description of 2019 pitches compared to other RHP:
His fourseam fastball is blazing fast. His slider is much harder than usual, has less than expected depth and has primarily 12-6 movement. His change (take this with a grain of salt because he's only thrown 3 of them in 2019) is basically never swung at and missed 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.
