BARCELONA ’92 OLYMPICS : Edberg’s Foibles Are All His Fault : Tennis: Swede, ranked No. 2, is upset by No. 47 Chesnokov, 6-0, 6-4, 6-4.

Andrei Chesnokov, who is not to be confused with Andre Agassi, although he is often confused with Andrei Cherkasov, finally produced an identification number Wednesday.

It is: 6-0, 6-4, 6-4.

With that score, Chesnokov knocked Stefan Edberg out of the 1992 Olympics in the first round in such overwhelming fashion that Chesnokov could not decide where to place the credit.

“I don’t know if I beat him,” Chesnokov said after his 1-hour, 38-minute romp. “Maybe he lost.”

Chesnokov’s English was broken, but his logic wasn’t. Edberg, the world’s No. 2-ranked tennis player and the second-seeded player here, threw this match in the trash. Chesnokov was simply smart enough to go scavenging for it.

Edberg double-faulted six times. His first-serve percentage was barely 50%. He committed 26 errors off his normally solid forehand, 31 off his backhand.

Edberg lost 10 of the match’s first 12 games, momentarily steadied himself and then failed to hold serve at 3-3 in the third set, followed by a throwaway at love to fall behind, 5-3.

“What can you say?” said Edberg, expressionless as always. “I played very badly, no doubt about it.

“I practiced 1 1/2 weeks for this tournament, on clay, and when I come out today, nothing felt right. I couldn’t keep the ball in the court.”

Edberg is a two-time Wimbledon champion and the winner of last year’s U.S. Open, but he also is capable of maddening lows. In the 1990 French Open, Edberg lost in the first round to Spain’s Sergi Bruguera, also on clay, also in straight sets. The previous year, Edberg had reached the French Open final. This year, he advanced to the Australian Open final in January and has since lost matches to such ATP tour fillers as Daniel Nestor, Jan Siemerink, Robbie Weiss, and Shuzo Matsuoka.

And now, Chesnokov. Ranked 47th in the world, Chesnokov was a first-round loser at both the French Open and Wimbledon this year and had never beaten Edberg, having taken one set from him before Barcelona.

“If someone was telling me before the match that I would win, and it would be 6-0, 6-4, 6-4, I can’t believe it,” said Chesnokov, 26, who is from Moscow.

“Maybe it was the weather. It was very hot on the court, quite difficult conditions for everyone.”

Chesnokov grinned.

“But right now,” he added, “I feel like a fish in the water.”

Today, Chesnokov is in the second round of the men’s field, along with Pete Sampras and Michael Chang.

The Americans, seeded third and sixth, respectively, advanced with ease Wednesday. Sampras swept Wally Masur of Australia, 6-1, 7-6 (7-4), 6-4, and Chang needed four sets to eliminate Alberto Mancini of Argentina, 6-1, 6-4, 3-6, 6-0.

Other seeded players advancing included No. 8 Michael Stich of Germany, a 6-3, 3-6, 6-1, 3-6, 6-3 winner over Richard Fromberg of Australia; No. 11 Bruguera, a 6-1, 6-2, 6-3 winner over Andrew Castle of Britain; and Cherkasov of the Commonwealth of Independent States, a 6-1, 6-0, 3-6, 6-1 winner over Roger Smith of the Bahamas.

Tenth-seeded Thomas Muster of Austria was eliminated by Henri Leconte of France, 7-6 (7-5), 7-6 (11-9), 6-4.

In the women’s draw, Jennifer Capriati needed less than an hour to defeat first-round opponent Elna Reinach of South Africa, 6-1, 6-0, but American teammate Zina Garrison was left behind. Garrison, a bronze medalist in Seoul, has been slowed by an ankle injury, leaving her vulnerable against South Africa’s Amanda Coetzer, who won, 7-5, 6-1.

“I’m just an event watcher now,” Garrison said. “The ankle felt fine today, but it hurt me in terms of preparation. I didn’t work out beforehand the way I need to. I maybe got in 45 minutes over two or three days.”

Garrison had been 12th-seeded, but given her physical condition, and clay surface, she said she was not expecting to do well.

“My goal was just have some fun,” she said.

Arantxa Sanchez Vicario of Spain, seeded second, advanced with a 6-1, 6-3 victory over Irina Spirlea of Romania. Spanish teammate Conchita Martinez (No. 5) also won on her home soil, defeating Judith Wiesner of Austria, 4-6, 6-1, 6-2.

So now, the tournament continues without Edberg, a three-time Olympian who won the tennis demonstration in Los Angeles in 1984 and a bronze medal in 1988. Shortly before sunset Wednesday, Edberg was asked a final question: Would this be his last Olympic appearance?

“I’m still young enough to play in the next one,” he replied, managing a smile.

“Hopefully, they’ll put down some grass courts in Atlanta.”
