I can't agree with Roddick - Mahut and RRH - Milos. Both the french and the canadian are very big favourites.
I would add to the list Anderson - Machado, since the south american is not good on clay, and it's Machado best surface...
Rui really needs that one to get an Olympic spot. If he loses, he will be dependent on many things to be in London, I think.
He better show up tomorrow, it's a very winnable match.
