I have to go with Safin on this one. He has had lots of rest. He loves this tournament, and Haas hasn't had very difficult competition leading up to the qtrs.
Really "has had a lot of rests" ????
He played on monday, tuesday and yesterday his double, so I don't think he had a lot of rest. I was at all the matches of both players, and Tommy played better than against Llodra, I was very surprised by the way he played today. Regarding Marat, as usual, many ups and downs and you don't really know what to expect with him.
I'll be there tommorrow, hopefully, there will be that match... I'm sure it's going to be a great match. I have no favourite, but two friends of mine who are comiing tomorrow, like both players (one Haas and one Safin). I just hope a great match, and good luck to both
