In 2015, they relied primarily on their Sinker (86mph) and Change (78mph), also mixing in a Curve (73mph). He also rarely threw a Cutter (82mph).
In 2015, compared to other LHP:
Their sinker is basically never swung at and missed compared to other pitchers' sinkers, has surprisingly little armside run and has below average velo. Their change (take this with a grain of salt because they've only thrown 18 of them in 2015) has surprising cut action, is an extreme flyball pitch compared to other pitchers' changeups and has below average velo. Their curve (take this with a grain of salt because they've only thrown 13 of them in 2015) has an exceptional bite, generates an extremely high number of swings & misses compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves, has primarily 12-6 movement and has slightly below average velo. Their cutter (take this with a grain of salt because they've only thrown 1 of them in 2015) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has some natural sink.
