when was the last time a No.1 player lost in the 4th round? it was nadal in 2009. and novak almost lost the match. he is feeling the pressure for sure to do a Novak slam. His quarterfinal looks to be Tsonga and then federer. Tough matches coming up for Novak. He hasn't won a clay tournament this year. Novak is not really a red clay expert like nadal. Novak is struggling. If it happens, the semifinal between Novak and federer will be a battle for sure. Federer once again has done well considering his age and has now reached the quaterfinals or more of a GRAND SLAM event since 2004. This includes 32 consecutive quaterfinals, 23 consecutive semis and 10 consecutive finals. That's an amazing record and impossible to break. GO FEDERER.
