 By stat cast data, it is by far his best pitch. Hitters are having a really hard time with it. It's really effective against righties and lefties. So he is kind of a different guy. Not that he didn't deserve to be the first overall pick, but I think it's really incredible for a guy who's 21, 22 years old to be the first pick, go out in the offseason and say, yeah, I need to add another pitch, and then show up the next spring, and it's the best thing in his arsenal.
