"It wasn't pretty," Stefanki said. "That tactic won't be used again. It was a very aggressive, offensive, bring-out-the-bugle-and-charge. And this guy is like (Mats) Wilander or (Bjorn) Borg — you give him a target and he's going to pass you, lob you, dink you, because he's a great mover off the ball."

This match could be decided by Roddick's serve against Murray's returns. Roddick pounded 43 aces past 2002 Wimbledon champion Lleyton Hewitt in Wednesday's quarterfinals, and he acknowledged that Murray is "certainly in the conversation among the best returners."

Roddick will have his new wife, his trainer and Stefanki in his corner Friday. Murray, meanwhile, will have roughly 15,000 supporters at Centre Court.

"It will certainly be something to remember," Roddick said. "I think the crowd's going to be electric. I think it's going to be a great atmosphere, and one that I can certainly appreciate, even if it's not for me. I'm just going to pretend when they say, 'Come on, Andy!' that they mean me."

Murray was the only British man or woman to get past the second round in singles and will be playing in his first Wimbledon semifinal.

Federer will be attempting to get to a record seventh consecutive Wimbledon final and record 20th career Grand Slam final. His match against Haas is the Swiss star's 21st Grand Slam semifinal in a row, extending a record he already owned.

"The consistency, right there, in the big tournaments is ridiculous," Murray said. "You know, no one will ever match that, I don't think."

By winning the French Open last month, Federer completed a career Grand Slam and tied Pete Sampras with 14 major championships.

Sampras has not said whether he'll show up if Federer has a chance to break that tie Sunday. Past performances certainly indicate Federer should be there.

After all, he is 19-3 in Grand Slam semifinals, and Haas is 0-3. Plus, Federer leads Haas 9-2 head-to-head, including a big comeback June 1 in the fourth round of the French Open, where the German took the first two sets and was five points from victory.

Federer, of course, came back.

"I stayed calm and I knew that if the match was going to swing around that it was going to be really difficult for him. It's exactly what happened," Federer said. "But new match, new tournament. We'll see what happens."
