Tennis Roundup : Annacone Overcomes Weakened Wilander

Third-seeded Mats Wilander of Sweden, weakened by stomach problems, lost to Paul Annacone in the Queens Club grass-court tennis championships Friday in London.

“I did not feel good from the beginning,” said Wilander, who was defeated, 6-2, 6-4. “It is just something that is going around and started in the morning. I just didn’t feel up to it.”

Annacone, who will face top-seeded Ivan Lendl in the semifinals, took advantage of the situation, attacking often.

Lendl was also pressed but had enough left to beat Michael Stich of West Germany, 6-4, 4-6, 6-3.

Others advancing to the semifinals were Derrick Rostagno, who turned back Gary Muller of South Africa, 6-7 (9-7), 6-2, 6-2, and Christo van Rensburg of South Africa, who downed Chris Bailey of Britain, 6-2, 6-4.

Martina Navratilova advanced to a semifinal match against Elna Reinach of South Africa in a tournament at Edgbaston, England.

Navratilova was almost invincible on her own serve, giving up only seven points in a 6-4, 6-2 victory over Australian qualifier Kristine Radford.

Reinach defeated American Betsy Nagelsen, 1-6, 6-3, 7-5.

In the other semifinal, second-seeded Zina Garrison will meet defending champion Claudia Kohde-Kilsch of West Germany. Garrison eliminated Japanese qualifier Kimiko Date, 6-3, 6-2, and the fifth-seeded Kohde-Kilsch beat Ann Henricksson, 6-2, 6-4.

John McEnroe overwhelmed Argentina’s Horacio De La Pena, 6-3, 6-3, in a grass-court tournament at Edinburgh, Scotland.

McEnroe lost to De La Pena in the first round of the 1987 French Open.

McEnroe will face Aaron Krickstein, who advanced when Brad Gilbert withdrew because of a stomach muscle injury. Gilbert was leading, 7-5, 2-4.

Fourth-seeded Ronald Agenor of Haiti made a string of unforced errors and double faults en route to a 7-6, 6-1 loss to Roberto Azar, 23, of Argentina, in the quarterfinals of a tournament at Bologna, Italy.
