In 2017, compared to other LHP:
Their sinker has heavy sinking action, has an obvious tail and is an extreme flyball pitch compared to other pitchers' sinkers. Their slider (take this with a grain of salt because they've only thrown 11 of them in 2017) generates an extremely high number of swings & misses compared to other pitchers' sliders, has exceptional depth, results in more flyballs compared to other pitchers' sliders and has primarily 12-6 movement. Their curve (take this with a grain of salt because they've only thrown 5 of them in 2017) is basically never swung at and missed compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves, has little depth and is slightly harder than usual. Their change (take this with a grain of salt because they've only thrown 2 of them in 2017) is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone and is an extreme flyball pitch compared to other pitchers' changeups.
