A dominating win by Roger Federer in his 1,000th career match and a more difficult workout for Rafael Nadal set up a
rare Grand Slam marquee semifinal between the former top-ranked players.
Four-time Australian Open champion Federer advanced to his ninth straight semifinal at Melbourne Park with a 6-4, 6-3, 6-2 quarterfinal win on Tuesday over Juan Martin del Potro, the man who beat him for the U.S. Open title in 2009.
Federer's 1,000th match was similar to most in his career - no-nonsense, dominating from the start and hitting some incredible shots.
"It's a lot of matches and a lot tennis,'' said Federer, a record 16-time Grand Slam champion.
"Either I have been around for a long time or I'm extremely fit. You decide which way you want to describe it. But I'm happy."

In an often tempestuous night match at Rod Laver Arena, Nadal advanced with a tough 6-7 (5), 7-6 (6), 6-4, 6-3 win over Tomas Berdych.
"Happy with how I finished match physically, I was able to keep running with high intensity,'' Nadal said.
Federer and Nadal - they were ranked 1-2 for many years - have been on opposite halves of the draw since the 2005 French Open. That was the last time the pair met in a Grand Slam semifinal, won that year by Nadal in four sets.
"The ranking is important, but we are talking about a player who has won 16 Grand Slams, and I've won 10,'' Nadal said.
"We have played a lot of matches together, many in very important moments for our careers. So the matches against him are always special, even if we are (ranked) 20 against 25.''
Knocked off the top
Defending women's champion Kim Clijsters, still dealing with a left ankle injury, advanced to an Australian Open semifinal against third-seeded Victoria Azarenka by beating No. 1 Caroline Wozniacki 6-3, 7-6 (4) on Tuesday.
Clijsters' victory ensured that Wozniacki would lose the top ranking she has held for most of the last 15 months.
Azarenka beat No. 8 Agnieszka Radwanska 6-7 (0), 6-0, 6-2. Azarenka is one of three women who could finish at No. 1 in Melbourne - Maria Sharapova and Petra Kvitova are the others.
In the late match, Nadal saved four set points in the first set, including one on an amazing crosscourt passing shot on the 29th point of a rally. But Berdych held firm to win the ensuing tiebreaker.

During the tiebreaker, a Berdych shot landed out, and Nadal returned it, then challenged. Chair umpire Carlos Bernardes wouldn't allow the challenge because Nadal hadn't immediately stopped play, but Nadal responded by saying he didn't challenge immediately because he thought the linesman had called it out.
The replay showed the ball was out.
"Carlos, I'll tell you something, you never get one right, not one correct overrule," Nadal said in Spanish.
"You're not here as a spectator. You know that ball was out."
Nadal was still debating the issue at his post-match news conference.
In the fourth set, Nadal chastised the chair umpire again for allowing a challenge by Berdych, feeling the Czech player waited too long before asking for a review.
In the opening game of the fourth set, Nadal hit consecutive down-the-line forehands to break Berdych's service and the Spaniard was on his way to clinch the match in 4 hours, 16 minutes.
Berdych said his performance "was only good, which means that is not enough with Rafa.''
Federer's career can be enhanced even more if he wins the title this year at Melbourne Park. With a 232-34 record in Grand Slam singles matches, he can overtake Jimmy Connors' mark of 233 wins if he collects the title here.
Del Potro, who has recovered from the right wrist injury that sidelined him for most of 2010, played well in flashes. But Federer was at another level, hitting lobs, drop shots, crosscourt winners and generally negating Del Potro's big forehand.
"We have played some big matches against each other, so just knowing how well he's been playing as of late, I was just hoping that I would get off a good start,'' Federer said.
"I was able to mix it up well and control the ball, and right away sort of felt confident.''
The end of the match came in a most fitting way, one of Federer's backhand winners.
Before that, Federer saved his fourth break point at 5-3 in the second set after a long rally. He let out a loud yell, unusual for a player not prone to big shows of emotion.
"That's why I didn't celebrate when I won the set, just to make it up."
Federer said, smiling. "I really knew how important that game was for me."
The quarterfinals on the other side of the men's draw are Wednesday - Andy Murray plays Kei Nishikori of Japan and top-seeded Novak Djokovic takes on David Ferrer.
In the remaining women's quarterfinals on Wednesday, Sharapova plays Ekaterina Makarova, who beat five-time champion Serena Williams in the fourth round, and No. 2 Kvitova takes on unseeded Sara Errani of Italy.
