The only thing I worry about is whether or not teams will find something he's doing that might be tipping his pitches. I'm not saying he is. My eye isn't good enough to see those sorts of tells, just that it's one thing to be able to throw every last pitch in the book. It's quite another to be able to do it AND disguise them all.
But the dude has come out of nowhere this season and is doing fantastic.
