PARIS -- Serena Williams glared at the ball, the lines and even her towel. Only after winning the final point did she crack a smile.

	Amelie Mauresmo had 34 unforced errors and six double faults.

An uncharacteristically stern Williams took a partisan crowd out of the match and sent Frenchwoman Amelie Mauresmo out of the French Open with a 6-1, 6-2 victory in the quarterfinals Tuesday.

With her 33rd consecutive victory in Grand Slam play, Williams avenged a loss to Mauresmo at Rome on May 17.

"At this stage of the tournament, you have to be ready for just about anything," Williams said.

In the semifinals Thursday, Williams will face the only other player to beat her this year, Justine Henin-Hardenne. The No. 4-seeded Belgian beat No. 8 Chanda Rubin 6-3, 6-2.

Williams won her first 21 matches this year before losing to Henin-Hardenne in the final at Charleston, S. Carolina, on April 13.

"I beat her the last time so she will have great motivation to take her revenge," Henin-Hardenne said of the top seed. "I'm the challenger but I really hope to make it to my first French Open final."

Henin-Hardenne, who has played in just one grand slam final -- at Wimbledon two years ago where she lost to the older Williams sister, Venus -- thinks she has the shots to disturb Serena.

"Serena obviously will say she did not play well when I beat her in Charleston, but I did not play too well either," she said. "We can talk a lot about this semifinal, but the answer will be on court."

Also advancing Tuesday was Henin-Hardenne's compatriot, No. 2 Kim Clijsters, who beat Conchita Martinez 6-2, 6-1.

"For the Belgians, it feels like a Belgian Grand Slam," Clijsters said.

But Clijsters, who pushed Serena to three sets in the Australian Open semifinals, admitted the American was undisputably the woman to beat.

"She's been on top of the game for quite a while already now. That's why she's won the last grand slams," the second seed said.

Clijsters' opponent Thursday will be unseeded Nadia Petrova, the first female Russian semifinalist at the French Open in 28 years. She beat compatriot Vera Zvonareva 6-1, 4-6, 6-3.

Petrova had the edge in a series of grueling baseline rallies against Zvonareva, who was coming off an upset of Venus Williams in the fourth round.

"I gave every bit of energy I have into this match," said Petrova, who is ranked 76th. "I'm so pleased with it."

The last Russian woman to play in the semifinals at Roland Garros was Olga Morozova in 1975.

Williams' match was her first since her sister lost, preventing a fifth consecutive all-Williams Grand Slam final. Serena is bidding for her fifth major title in a row, a streak that began at last year's French Open.

"I'm on a mission," Williams said. "I plan on reaching it."

The center-court crowd was eager to see the fifth-seeded Mauresmo stage an upset, but instead an overpowering Williams raced to a 4-0 lead, winning 16 of the first 19 points. After Mauresmo made it 4-1, Williams won six games in a row and again led 4-0.

The 64-minute rout ended with Mauresmo dumping a backhand into the net on match point.

"I didn't play my best tennis," she said. "I was feeling a bit nervous. I only started to play well in the last games of this match. It's something I regret."

Mauresmo committed 34 unforced errors, double-faulted six times and hit just five winners to 24 for Williams.

"I've seen Amelie play a little bit better, but I also played well," Williams said. "It's hard to play your best when I'm playing really well."

Petrova, who upset Jennifer Capriati in the fourth round, won despite struggling with her serve against Zvonareva. Six consecutive breaks in the final set made the score 3-all before Petrova held with an ace.

She broke again by winning a 49-stroke rally, which she finished off with a forehand winner to take a 5-3 lead. Petrova raised her arms in jubilation, then pounded her chest with her fist.

Zvonareva, seeded 22nd, extended some rallies by hitting moon balls -- a tactic rarely seen in recent years at Roland Garros. She won a 39-stroke exchange to save the first match point, but Petrova then smacked a service winner for the victory.

Petrova blew kisses to the crowd and flexed her arm. She said she was proud of the way she bounced back after losing the second set.

"I just said, 'C'mon, there's no wasting of energy just in the stupid emotions. Just keep everything into the points,' " Petrova said.

Zvonareva, 18, said the pressure of playing in her first Grand Slam quarterfinal wasn't a factor.

"Nadia was playing unbelievably good today," Zvonareva said. "She didn't make any mistakes."

Clijsters, the runner-up at the 2001 French Open, hit 29 winners against Martinez, who was playing the quarterfinals for the 11th time. The Spaniard committed 35 unforced errors and walked to the exit shaking her head.

"I had to have a lot of patience because the rallies were taking long," Clijsters said. "It was tough with her slices, but I did it well."

The crowd at Court Suzanne Lenglen included Clijsters' boyfriend, top-ranked Lleyton Hewitt, who was upset in the third round of men's singles.
