Basic description of 2016 pitches compared to other LHP:
His fourseam fastball has good "rising" action and has slightly below average velo. His cutter is a real worm killer that generates an extreme number of groundballs compared to other pitchers' cutters. His change has surprising cut action, has below average velo, has an extreme amount of backspin and results in somewhat more flyballs compared to other pitchers' changeups. His sinker (take this with a grain of salt because he's only thrown 6 of them in 2016) generates an extremely high number of swings & misses compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has little sinking action compared to a true sinker and has slight armside run. His curve (take this with a grain of salt because he's only thrown 5 of them in 2016) has very little depth, is basically never swung at and missed compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves and has slight glove-side movement. His slow curve (take this with a grain of salt because he's only thrown 2 of them in 2016) is a real yakker that's separated from his other curveball due to its big drop and slow speed.
