Men's top seed Stefan Edberg and women's second seed Monica Seles were handed early challenges yesterday in the draw for next week's French Open.

Edberg, who never has won the clay court tournament, will play Spain's Sergei Bruguera in the first round, and faces a possible stiff test in the second against fellow Swede Jonas Svensson.

Svensson, ranked 24th in the world, reached the semifinals of the French Open two years ago, upsetting then-defending champion Ivan Lendl.

Seles, who has won 24 consecutive matches and last week beat top-ranked Steffi Graf for her fifth straight tournament title, has a fairly easy first-round match against Katia Piccolini of Italy, ranked 100th in the world. But in the second round, Seles would face either Catarina Lindqvist of Sweden, No. 29 and a Wimbledon semifinalist last year, or Helen Kelesi of Canada, No. 22 and a French Open quarterfinalist the last two years.

Graf, the women's top seed, drew Pascale Paradis of France in the first round and could face 1981 French Open champion Hana Mandlikova in Round 2.

The defending women's champion, Arantxa Sanchez Vicario of Spain, drew a wild card entry, France's Noelle Van Lottum, in the first round. Sanchez Vicario is seeded third.

In the men's field, defending champion Michael Chang of the United States enters the tournament in a slump, and he wasn't helped by the draw. His first-round opponent is Casio Motta of Brazil. He could face Italy's Paolo Cane, a fine clay-court player, in the second round. And the third-round opponent could be Miloslav Mecir, a former top 10 player who has slipped to No. 61 while fighting injuries. . . .

In Dusseldorf, West Germany, Jim Courier and Brad Gilbert scored straight-set singles victories as the United States beat the Soviet Union, 2-1, to advance to the final of the $1.3 million ATP World Team Cup.

Courier beat Alexander Volkov, 6-4, 6-2; Gilbert defeated Andrei Cherkasov, 6-2, 6-3.

Courier and Ken Flach were upset, 3-6, 6-1, 7-6, by Andrei Olshovski and Vladimir Gabrichidze in the doubles, but the defeat did not influence the outcome. . . .

In Marbella, Spain, the host country took a 2-1 lead over the United States in the Nation's Cup as Sanchez Vicario and Conchita Martinez overwhelmed Zina Garrison and Lori McNeil in doubles, 6-1, 6-3.

The outcome of the clay court event will be decided today when Jennifer Capriati faces Sanchez Vicario in the opening singles and Garrison plays Martinez.
