WIMBLEDON, England — Rising, rising, rising, high above the most famous patch of grass in tennis, Roger Federer channeled Pete Sampras on match point in the Wimbledon semifinals Friday, tucking both feet back beneath his body and uncorking an overhead smash.

And now, after years of chasing Sampras, Federer is poised to surpass him.

A victory over No. 6-seeded Andy Roddick in Sunday's final at the All England Club would give Federer his 15th Grand Slam singles championship, breaking a tie with Sampras for the most in history. It also would give Federer a sixth Wimbledon title and a No. 1 ranking.

As it is, No. 2 Federer's overwhelming 7-6 (3), 7-5, 6-3 victory over No. 24 Tommy Haas of Germany on Friday put the Swiss star in a seventh consecutive Wimbledon final and 20th career Grand Slam final — establishing two other marks.

"I'm very proud of all the records I've achieved, because I never thought I would be that successful as a kid. You know, I would have been happy winning a couple tournaments and maybe collecting Wimbledon," the 27-year-old Federer said. "It's quite staggering."

Yes, Roger, it certainly is.

When he finished off Haas with that Sampraslike leaping putaway, Federer simply waited at the net to shake hands. Then he gave a little wave of his racket in the direction of his pregnant wife, his parents and other supporters in the guest seats above a scoreboard, before making the same gesture toward the Royal Box, where past greats of the game Bjorn Borg and Rod Laver were among the invited guests.

Winning a Wimbledon semifinal — indeed, any Grand Slam semifinal — is all so very been-there, done-that for Federer: He is 20-3 in major semis over his career, reaching 16 of the past 17 major finals.

"I know what's on the line," Federer said. "I hope I can play another good match."

His previous match against Haas, on June 1 in the fourth round of the French Open, was much tighter. Haas won the first two sets that day — drew within five points of victory, even — before Federer came back en route to winning the title at Roland Garros to complete a career Grand Slam and tie Sampras with 14 Grand Slam championships.

This time, Federer was quite close to perfect. He won a remarkable 72 of 83 points on his serve, did not face a single break point and finished with 49 winners and only 15 unforced errors.

"You know, that's the way it goes playing against him," Haas said. "There aren't really any weaknesses."
