PARIS, MAY 29 -- Stefan Edberg and Boris Becker, seeded first and second, crashed out of the French Open tennis championships today on an unprecedented day of first-round upsets.

Edberg became the first top seed in the history of the French portion of the Grand Slam to bow out in the opening round, losing, 6-4, 6-2, 6-1, to Spaniard Sergi Bruguera.

Becker did little better, taking only one set from another clay court specialist, Yugoslav Goran Ivanisevic, who triumphed, 5-7, 6-4, 7-5, 6-2.

It was the first time in Grand Slam history that both the top two seeds had been beaten in the first round and marked the first time Edberg had been seeded first in a Grand Slam event. Top-ranked Ivan Lendl skipped this event to prepare for Wimbledon.

"There are many tough players in the draw who aren't seeded and can beat you on a good day," Becker said. "He played very well and is going to beat more players. . . . I hoped that the longer the match went on, the more tired he would become but it went the other way. In the fourth set no one in this world could have stopped him."

Becker, who had never lost in the first round of a Grand Slam event, looked to be in contol at first. But Ivanisevic, who beat Becker in an exhibition match three weeks ago, responded by breaking the Wimbledon and U.S. Open champion's serve in the third game of the second set.

Using his powerful serve and forehand to maximum advantage, he took the second set, clinching the deciding point with one of several aces. He had 19 for the match.

In frustration Becker often overhit and found himself dragged into long, tiring rallies. Ivanisevic, ranked 51st, broke once again at 6-5 in the third set and never let up.

"I played the best tennis of my life," Ivanisevic said. "I beat him three weeks ago in an exhibition match but this is the real thing."

Edberg, whose only previous first-round exit was at the U.S. Open as a 17-year-old in 1983, looked ordinary.

With Edberg up 4-2, Bruguera ran off seven straight games to take the first set and go up by 3-0 in the second. He broke twice in the third set in spectacular fashion. In the fourth game, Bruguera blunted Edberg's first serve with a chip forehand return down the line. Two games later, he broke again, ripping four passing shots, and taking a 5-1 lead.

Bruguera served out the 88-minute match in the next game at 15, with Edberg sailing a backhand long on the final point.

"I made too many unforced errors," said Edberg, beaten in both the French and Wimbledon finals last year. "Under normal circumstances, even on clay, I should beat him."

Ecuador's Andres Gomez, the fourth seed, defeated Fernando Luna of Spain, 7-6, 6-1, 7-6. No. 7 Thomas Muster beat Lars Jonsson of Sweden, 7-5, 6-3, 6-2, and No. 8 Andrei Chesnokov crushed Uwe Riglewski of West Germany, 6-1, 6-1, 6-3. Aaron Krickstein, seeded No. 5, posted a 6-0, 2-6, 6-3, 6-3 win over Jaime Yzaga of Peru.

The women's section ran true to form with defending champion Arantxa Sanchez Vicario and second seed Monica Seles advancing easily.

Sanchez Vicario, who last year shocked No. 1 Steffi Graf in the final, crushed France's Noelle Van Lottum, 6-1, 6-3. Seles looked even more impressive. The 16-year-old, who in West Berlin last week ended Graf's 66-match unbeaten run, crushed Italy's Katia Piccolini, 6-0, 6-0.

Florida teenager Jennifer Capriati sailed through her Grand Slam debut by demolishing Sandrine Testud of France, 6-1, 6-1.

Mary Joe Fernandez, seeded seventh, advanced with a 6-4, 6-2 win over Kate McDonald of Australia; No. 6 Manuela Maleeva of Bulgaria, No. 10 Natalia Zvereva of the Soviet Union and No. 16 Laura Gildemeister of Peru also won.
