This was reported over at Roger's website. (This was right after Stan lost his single's match). I hope Stan's ok. He played ok in the doubles...so that's good news:
"Don't know if you have discussed this already, but I read Stan was a little feverish at the beginning of the match. Maybe he's sick and that's why he didn't do so well in the singles.
