Nick Wittgren has thrown 3,200 pitches that have been tracked by the PITCHf/x system between 2013 and 2019, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2019, he has relied primarily on his Fourseam Fastball (93mph), also mixing in a Curve (84mph) and Change (86mph).
Basic description of 2019 pitches compared to other RHP:
His fourseam fastball generates more whiffs/swing compared to other pitchers' fourseamers and has essentially average velo. His curve is thrown extremely hard, has very little depth, has primarily 12-6 movement and results in somewhat more flyballs compared to other pitchers' curves. His change generates fewer whiffs/swing compared to other pitchers' changeups, is slightly firmer than usual and has some natural sink to it.
