Perhaps Roger Federer does not quite tie or break records every time he takes the court at Grand Slam tournaments.

It sure feels as though he does.

Federer can reach a 20th Grand Slam final - something no man ever has done - and move within a victory of his 15th career major title - never been done, either - by beating Tommy Haas in today's Wimbledon semi-finals.

"It's fun playing the biggest matches. Especially, I like playing best-of-five-set matches. And maybe this is where I'm best, because everything comes out," Federer said. "Not only your mental strengths, but physical, tactical skills."

Consistency

He is seeking a sixth Wimbledon championship and the match against the 24th-seeded Haas is the Swiss star's 21st Grand Slam semi-final in a row, extending a record he already owned. Overall, Federer is 19-3 in major semi-finals; Haas is 0-3.

"The consistency, right there, in the big tournaments is ridiculous," said Andy Murray, who will meet Andy Roddick in the other semi-final. "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.

He 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.
