NEW YORK — Pam Shriver, taking full advantage of an opponent who felt she was being cheated and so gave up in disgust, won 12 of the final 14 games Thursday night to upset Hana Mandlikova, 4-6, 7-5, 6-1, and earn a berth in the semifinals of the $1-million Virginia Slims championships.
Martina Navratilova followed with a routine 6-2, 6-4 victory over Bettina Bunge, running her winning streak since early June to 51 matches. The defending champion, who is seeded No. 1, will meet Shriver in the semifinals, and Navratilova has won her last 19 matches against her doubles partner.
Mandlikova appeared well in control when she led, 4-1 and 5-3, in the second set, but she finally lost her cool following a series of calls that went against her. Mandlikova, seeded third, held service to open the final set but offered only token resistance as Shriver swept the final six games with the loss of six points.
In a statement, Mandlikova said: "I've played a hundred matches and I've never been cheated like this before. I don't want to take anything away from Pam. I was playing my best tennis at the beginning and I felt I was being cheated. I can fight to a certain moment, but then it's too much."
