It isn't very often that Roger Federer is reduced to mere mortal status, but when he exited the court for a medical timeout today, the Centre Court crowd fell silent.
Federer would return after an eight-minute delay to finish off Xavier Malisse in four sets 7-6, 6-1, 4-6, 6-3 to reach his 33rd consecutive Grand Slam quarterfinal, extending his own record.
"Honestly I'm not too worried," he said. "I've had bad backs over the years. They go as quick as they came. But of course I have to keep an eye on it now. Two good nights' sleeps, and I'll be 100 percent on Wednesday. I'm pretty convinced, otherwise I wouldn't have been able to pull out the match the way I did today."
He is 13-0 against his next opponent Mikhail Youzhny.
In the only other men's match to finish because of rain, defending champion Novak Djokovic dispatched Serb Viktor Troicki in three sets in a mere 90 minutes.
Rain suspended all other men's matches today.
