Those H2Hs are meaningless and mostly pretty old. I mean, Sampras, Rafter, Ivanisevic, and Henman are all retired and irrelevent. Youzhny is one of those late-bloomers playing better and better as he ages and matures. So much pressure on his shoulders when he was young, and now he's beginning to live up to it. Honestly, the sky is the limit.
I actually like how Misha's game matches up against serve and volleyers. He knows how to hit a passing shot, he's very accurate, and he can also take the net away from opponents by coming in himself. He's also good at chipping returns back in play off his forehand and backhand, which will be useful against Tsonga. I'm predicting a high quality 4 or 5 set QF, and it will come down to who manages their nerves and their serve better! I (cautiously) predict my man Mish. But Tsonga is one of those guys who can blow you off the court if everything is working. But Youzhny is smarter and more experienced.
