David Wheaton defeated Petr Korda, 6-4, 6-2, and Zina Garrison beat Regina Rajchrtova, 6-4, 6-4, as the United States advanced to the semifinals of the Hopman Cup team tournament with a 2-1 victory over Czechslovakia at Perth, Australia.
Korda and Rajchrtova recovered to beat the American pair, 8-1, in a mixed doubles match that was reduced to one set after the top-seeded United States clinched the match with its 2-0 lead.
The United States will face the Swiss team of Jakob Hlasek and Manuela Maleeva-Fragniere in the semifinals. France's Guy Forget and Catherine Tanvier will face the Yugoslav team of Goran Prpic and Monica Seles in the other semifinal. . . .
Akiko Kijimuta of Japan spoiled Pam Shriver's return to competition with a 6-4, 6-2 victory in the first round of the Danone Open at Brisbane, Australia.
Kijimuta repeatedly passed Shriver, playing her first tournament in nine months after having surgery on her right shoulder, at the net on her way to the victory.
Shriver, once the third-ranked player in the world and the winner of 21 Grand Slam doubles title during her 13-year professional career, said she wasn't downhearted by the loss. "My comeback is a 12- to 18-month project," she said.
