I saw Cotton last year as a reliever and wasn't too impressed with the stuff, granted it was only a one inning burst, but this was a different pitcher. He commanded the fastball the majority of the game and held his velocity throughout. Because of his size and drop and drive mechanics, he loses plane from his fastball which can be a problem if the pitches are up in the zone. On this occasion, he made few mistakes and varied his pitch sequence well. The changeup is an above-average offering and is his ticket to the major leagues, in my opinion. Unfortunately, his profile is limited due to a below-average curveball that doesn't have much bite at present and much projection in the future. I can see a middle reliever role if it all clicks, going with his plus two pitch mix exclusively.
