Thousands remained transfixed to the giant screen on Henman Hill to join the 15,000 fans inside the stunning arena cheering for Andy Murray to a 2-6, 6-3, 6-3,5-7, 6-3 victory against Stanislas Wawrinka.
Dubbed as Prince of Darkness, Murray survived the five-set sweat-fest against the Swiss no.2 under Centre Court’s new roof.
Earlier of the day, Federer outserved Robin Soderling 6-4, 7-6 (5), 7-6 (5) to reach the Wimbledon quarterfinals—three weeks after downing the Swede in three sets in Paris for his first French Open title.
Lleyton Hewitt, Juan Carlos Ferrero and Tommy Haas also produced vintage displays at Round 4 at the Wimbledon.

In the women's singles, a tearful Ana Ivanovic retired 1-6, 1-0 after a leg injury in her fourth-round match against Venus Williams.
Ivanovic took a 10-minute break during the first game of the second set to have her left thigh taped by a trainer.
She returned for two more points, but after hitting a service winner to take the game, she began crying as she walked to her chair and told the umpire she was retiring.
The new retractable roof over Centre Court was closed for the first time Monday after a light sprinkle halted play during the second set of a match between Dinara Safina and Amelie Mauresmo.
