Well, I can't see the uni number or head and the person that took the pic says it's Wharton. It was posted often in threads about the NO bounty & Vilma and posters said it was Wharton. So I'm going with that. Besides Stewart wears pink for the breast cancer games and that person isn't wearing any pink. Also, that guy is too tall to be Stewart.
So, no. I do not think it is Stewart. It is Wharton.
But it doesn't matter what you think...we all know that it's Stewart
