Tipsarevic and Tsonga are both first round casualties, if Gasquet wins this tournament he bumps up into 9th and puts himself in a great position to make it to the London. Finals would also be good, as I think Gasquet will play well in Paris.
You are making big assumptions here. That's like saying if Richard wins AO, then RG, then Wimbledon, he may actually become number 1.
Fact is, let's me realistic. He is playing Youzhny who has won his last 4 out of 5 matches with scores:
6-3, 6-1. He did lose to Berdych, but he still it shows that he is playing at very high level and I am not even sure Richard is coming in as favorite in this match..
