But Mats Wilander, another of the world’s leading players bidding for a first Wimbledon title, continued his poor season by losing to Paul Annacone of Bridgehampton, N.Y., 6-2, 6-4.

Martina Navratilova eased into the semifinals of a $150,000 Virginia Slims event today with a 6-4, 6-2 victory over Australian qualifier Kristine Radford at Edgbaston, England.
