WIMBLEDON, ENGLAND, JUNE 16 -- Top-seeded Boris Becker, out to win a third consecutive men's championship at Wimbledon, drew a tough first-round opponent today as the tournament pairings were announced.

In the women's field, top seed and defending champion Martina Navratilova was matched against a relatively unknown West German in the first round and, barring upsets, would meet longtime rival Chris Evert in the semifinals.

Becker, trying to join Bjorn Borg of Sweden and Fred Perry of Britain as the only men in the modern era to win three consecutive Wimbledon titles, will open play on Centre Court Monday against Karel Novacek of Czechoslovakia. In the French Open, Novacek made it to the quarterfinals before losing to another Czech, Miloslav Mecir.

Ivan Lendl, on the other hand, will have to wait until Sunday before knowing his first-round opponent. He is ranked first in the world but is seeded second on Wimbledon's grass.

Becker is paired to meet two seeded U.S. players, No. 15 David Pate in the fourth round and No. 7 Jimmy Connors in the quarterfinals.

Navratilova, who would break Suzanne Lenglen's record of five consecutive Wimbledon women's championships and match Helen Wills Moody's record of eight overall by winning this year, opens against Claudia Porwik of West Germany, ranked 93rd in the world.

Navratilova is scheduled to meet Bulgarian sisters in consecutive rounds -- 15th-seeded Katerina Maleeva in the fourth round and eighth-seeded Manuela Maleeva in the quarterfinals -- before Evert.

Evert, a three-time Wimbledon champion seeded third, plays Britain's Sara Gomer in the first round. Her draw would put her against fifth-seeded Helena Sukova of Czechoslovakia in the quarterfinals.

Steffi Graf, the French Open champion and second seed, opens against Adriana Villagran, an Argentine who gave Navratilova trouble in an early-round match in Paris.

If results hold to the form of the seedings, Graf would meet 13th-seeded Wendy Turnbull in the fourth round, No. 7 Gabriela Sabatini in the quarterfinals and fourth-seeded Hana Mandlikova in the semifinals.
