The men get a day off before their quarterfinals Wednesday, when the matchups will be No. 2 Federer vs. No. 22 Ivo Karlovic of Croatia, Murray vs. 2003 French Open champion Juan Carlos Ferrero, Djokovic vs. No. 24 Tommy Haas, and Roddick vs. 2002 Wimbledon champion Lleyton Hewitt, who lost the first two sets but came back to beat No. 23 Radek Stepanek 4-6, 2-6, 6-1, 6-2, 6-2.

“Lleyton and I have built up a very healthy respect for one another throughout the years,” said Roddick, who smacked 24 aces, never faced a break point and eliminated No. 20 Tomas Berdych 7-6 (4), 6-4, 6-3. “We’re a couple of the old guys now.”

Well, Roddick is 26, and Hewitt is 28. Neither has anything on Haas, who at 31 was the oldest man to reach the fourth round and now meets the youngest, Djokovic, who was born a week after Murray.

Federer improved to 11-0 against Robin Soderling by beating him in straight sets in a rematch of the French Open final three weeks ago. Now Federer has to deal with Karlovic, at 6-foot-10 the tallest player in tour history, who pounded 35 aces and served 10 games at love while defeating No. 7 Fernando Verdasco 7-6 (5), 6-7 (4), 6-3, 7-6 (9). Karlovic leads Wimbledon with 137 aces and has gone 128 service games over his past two tournaments without being broken.

“I mean maybe it’s not the most fun match to go through,” Federer said. “But I like to beat this guy because he makes it hard on us.”

Federer and Wawrinka teamed to win the doubles gold medal at last year’s Beijing Olympics. Otherwise, Wawrinka never has come close to approaching his friend’s success. Bidding to reach his first major quarterfinal, though, Wawrinka gave Murray plenty of trouble.

It all felt more like a theater than a sports venue, thanks to the surroundings and the momentum shifts. Wawrinka came out playing superbly, then things swung in Murray’s favor. With the local favorite seemingly in control, Wawrinka stole the fourth set. And in the fifth, which began at 9:56 p.m., Murray raced to a 3-0 lead, before Wawrinka took the next three games. Then Murray closed with a three-game run.

Sounds echoed with the roof closed on Centre Court, which originally was constructed in 1922. All those shouts of “Come on, Andy!” from all of those spectators waving Union Jacks and Scottish flags reverberated around the arena as hundreds of other people watched on a TV screen set up outdoors.

“At the end, it was probably the noisiest crowd I’ve ever played in front of,” Murray said. “It definitely sounds and feels much louder under the roof.”

Even Wawrinka was able to appreciate the setting, if not the result.

“I enjoy a lot the match,” Wawrinka said. “But for sure, I’m very sad after the match.”
