You won't get a lot of post-race interviews from the new 450 champ. He was being interviewed in the press conference afterwards, and mentioned that he'd felt like he'd gotten food poisoning the night before. He then got the chills, asked for a sweatshirt, and peaced out on the press conference.
Apparently he'd also been sick during the day.
Get well soon, champ, and way to overcome some adversity late in the season.
