Basic description of 2019 pitches compared to other LHP:
His fourseam fastball has less armside movement than typical and has slightly above average velo. His change is thrown extremely hard, generates a very high amount of groundballs compared to other pitchers' changeups and has some natural sink to it. His curve has an exceptional bite, results in somewhat more groundballs compared to other pitchers' curves 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.
