PARIS (AP) -- Smiling wickedly as she slugged winners, Martina Hingis silenced the boos from hostile French Open fans and turned a grudge match against Amelie Mauresmo into a routine romp.

A less bellicose but still unfriendly crowd showed no sympathy for Hingis' top-ranked male counterpart, Yevgeny Kafelnikov, who bumbled along in his reign of error.

Kafelnikov drew boos and whistles of his own in a listless 6-4, 6-1, 6-4 second-round loss Wednesday to 21-year-old Slovak Dominik Hrbaty.

``For the fans to see the No. 1 player in the world losing in the early stages of the tournament, it's really frustrating,'' Kafelnikov said.

Kafelnikov reached No. 1 on May 3 despite six straight losses and has done little since to justify his status. He would lose the top spot if Pete Sampras or Patrick Rafter reach the quarters at the French.

No. 5 Richard Krajicek also exited meekly, falling 6-1, 6-2, 6-2 against American Vince Spadea.

It was another hot, grueling day on the clay at Roland Garros for several of the seeded players.

Defending champion and fourth-seeded Carlos Moya endured a 6-7 (5), 6-4, 6-3, 6-1 match against Petr Korda; and No. 13 Andre Agassi overcame the inspired play of 82-ranked Frenchman Arnaud Clement, 6-2, 4-6, 2-6, 7-5, 6-0.

Agassi, who played a tough four-setter in the opening round, was two points from defeat when he trailed 0-30, 4-5 on serve in the fourth set. A couple of big groundstrokes saved him, then he watched Clement wilt in the heat with a case of leg cramps.

``I didn't get lucky that he cramped, I worked for that,'' Agassi said.

But the big buzz all day -- indeed, all week -- was the Hingis-Mauresmo match. More than national pride was at stake. There was Mauresmo's honor to defend.

The crowd came to roast Hingis and toast Mauresmo, a Frenchwoman whose openly lesbian relationship and broad-shouldered physique Hingis cruelly joked about at the Australian Open in January. ``Half a man,'' Hingis called her, and the jibe reverberated on the other side of the world

Yet the boos that greeted Hingis in the warmup faded amid her winners and Mauresmo's errors in the match, and the 6-3, 6-3 result was similar to Hingis' straight sets victory Down Under. A duel that everyone thought would sizzle quickly fizzled and fell as flat as day-old champagne.

Hingis couldn't have been happier to put this one behind her.

``It's like a heavy rucksack of stones has fallen off my back, and I feel much lighter,'' Hingis said.

Asked if she had fun on the court, Hingis replied:

``Not when we were hitting the first shots in the warmup. It was like, 'Allez, boo, allez, boo.'''

She attributed Mauresmo's wild performance to a case of homecourt nerves. Mauresmo's image adorned billboards and building walls around the city, and she was hyped as France's big hope on prime-time TV.

``Everybody was putting pressure on her,'' Hingis said. ``Everybody had big hopes she might win this tournament. Sometimes it doesn't help, the crowd and everything.''

In another poke at Mauresmo's muscular build, Hingis even suggested that the Frenchwoman may have been too strong for her own good.

``I don't think she has that much feel on court when she's in too-good shape,'' Hingis said. ``Sometimes you overrun the balls and don't think that much if you are physically very strong.''

Mauresmo, who beat Hingis when they last met three months ago in the Paris Indoors tournament before a similarly raucous and partisan crowd, shrugged off the suggestions that she was too nervous or too strong to win this time.

Mauresmo came into the match saying Hingis' comments in Australia were not forgotten and would continue to give her an extra incentive. But she didn't feel it interfered with her play.

``I was a bit tense, obviously, but she was tense as well,'' Mauresmo said. ``I think the match was going well for me. At 3-2, I broke, I'm leading 30-love. Then I miss one of the volleys. I really wanted to push it. I really wanted to make something great.

``From that point on, I suppose I did everything a bit too quickly, and probably overdid it. I wanted to finish the points too quickly.''

Hingis broke Mauresmo's serve three times in the second set, the last time for the match when Mauresmo mis-hit two shots about 15-feet out, then whacked a final forehand wide.

When they met at the end, they shook hands amiably and exchanged a few pleasant words. There was nothing to betray any underlying animosity.

``We don't love each other, but I think it's a professional relationship,'' Hingis said. ``We have to play each other. We both are very good players, so I think we will have to play each other more often in other tournaments.''

In other women's matches, defending champion Arantxa Sanchez-Vicario, sisters Venus and Serena Williams, and No. 4 Jana Novotna advanced.

Other men to reach the third round included No. 7 Tim Henman, No. 9 Marcelo Rios, No. 12 Greg Rusedski, and unseeded Russian Marat Safin.

Unseeded Jim Courier, a two-time French champion, lost to Hicham Arazi 2-6, 6-3, 6-4, 6-1.
