PARIS, JUNE 3 -- Andre Agassi settled a score with Jim Courier with a brilliant display of power tennis in the French Open today, setting up a quarterfinal meeting with defending champion Michael Chang.

Third-seeded Agassi lost a first-set shootout, then wore down No. 13 Courier, 6-7 (8-10), 6-1, 6-4, 6-0, avenging a third-round loss here last year. Eleventh-seeded Chang, who seems to be getting stronger every round, crushed Javier Sanchez, 6-4, 6-4, 6-2.

Fourth-seeded Andres Gomez reached the quarterfinals via a walkover as No. 16 Magnus Gustafsson withdrew with a knee injury.

Among the women, 14-year-old Jennifer Capriati continued her history-making run at Roland Garros, becoming the youngest quarterfinalist in a Grand Slam event, trouncing Mercedes Paz, 6-0, 6-3. Paz had eliminated 1989 champion Arantxa Sanchez Vicario in the third round.

Top-seeded Steffi Graf, practically recovered from allergy and sinus problems, powered into the final eight by beating Nathalie Tauziat, 6-1, 6-4. Mary Joe Fernandez, the seventh seed, beat Ann Grossman, 6-3, 6-2. Also reaching the quarterfinals were No. 6 Manuela Maleeva, 6-4, 6-2, over No. 10 Natalia Zvereva; her sister, No. 8 Katerina Maleeva, 3-6, 6-3, 6-3, over Nicole Provis; and No. 9 Conchita Martinez, 6-3, 6-3, over Wiltrud Probst.

Capriati will face Fernandez, Graf will play Martinez. The other pairings haven't been determined because of rainouts today. Two women's and two men's matches were postponed till Monday.

Rain delayed the start of the Agassi-Courier match on Court Central and an intermittent drizzle had spectators using umbrellas in the third and fourth sets.

Agassi and Courier have been rivals since their days at Nick Bollettieri's academy. While Bollettieri remained Agassi's ever-present mentor, Courier left the academy because he thought he wasn't getting enough attention. Agassi's entourage today included Bollettieri.

"I was really up to play Jim," Agassi said. "I felt like I had a few more gears to shift into."

In the first set they relentlessly fired forehands and two-handed backhands. There were no service breaks as Courier saved two break points and Agassi one. In the tiebreaker, Agassi had three set points. During a long rally on the third set point, he fell down, giving Courier an open court for 8-8.

Courier then crunched a backhand winner and closed out the set on the next point when Agassi slapped a backhand into the net.

"Jim always comes out just banging balls in the first set," Agassi said. "I was just hoping to stay close in the first set. That was icing on the cake. Then I kicked into high gear."

Agassi broke Courier twice in the second set. The third set was decided by Agassi's single service break in the fifth game. Courier had nothing left in the fourth set.

"He was the aggressor," Courier said. "After the first set, I couldn't take control of the points. I was always on the run."

"I'm a different player from last year," Agassi said. "I have a lot more physical strength. And when you're physically strong, it's tough not to be mentally strong."

Conspicuously absent from his usual seat was Philippe Chatrier, president of the French and International Tennis federations.

Chatrier has threatened to ban Agassi's flourescent pink and black outfits, prompting the American to call him and other tournament officials "bozos."

Agassi today accused Chatrier of setting a double standard by allowing sponsors' billboards at Court Central while complaining that bright clothing goes against tradition.

"When it comes to him reaping benefits, he doesn't care a whole lot about tradition, does he?" Agassi said.

Chatrier refused to comment on the matter but said he hopes Agassi wins the tournament.

To do so he'll have to get past Chang. The two have played twice -- both in New York in 1988 -- with Agassi winning at Forest Hills and the U.S. Open.

"We're similar in a sense," Agassi said. "We both hit well from the baseline. But I'm a bit more explosive than him. I can hit more winners. I'll go in confident."

Chang said Agassi is the favorite, thanks in part to his new physique. "Just look at him, he's this thick," Chang said, holding his hands far apart. "He's a real monster."

Another player achieving a fearsome repuation is Capriati, who has lost the fewest games (14) of any player remaining.

"I'm very happy I have reached this far, but I'm not going to stop," she said. "I'm really going to try to win this thing. Why not? I've come this far." TODAY'S FEATURED MATCHES Court Central
