Basic description of 2019 pitches compared to other LHP:
His fourseam fastball generates a high number of swings & misses compared to other pitchers' fourseamers, has less armside movement than typical, results in somewhat more flyballs compared to other pitchers' fourseamers and has slightly above average velo. His change is thrown extremely hard, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups, has slight armside fade and has some natural sink to it. His curve has a sharp downward bite and has slight glove-side movement. His cutter generates an extremely high number of swings & misses compared to other pitchers' cutters, has some natural sink and has strong cutting action. His sinker (take this with a grain of salt because he's only thrown 1 of them in 2019) generates an extremely high number of swings & misses compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run, has well above average velo and has little sinking action compared to a true sinker.
