Competing in her first match since capturing the Pan Pacific Open in Tokyo last month, Hingis defeated Chanda Rubin of the United States, 6-3, 6-3, in a second-round match.

Only five weeks after meeting in the Australian Open semifinals, second seed Lindsay Davenport battles resurgent Jennifer Capriati tonight in an all-American second-round clash.

Seventh seed Sandrine Testud of France earned a quarterfinal meeting with Hingis by downing Amy Frazier of the United States, 7-5, 6-0. Testud lost to Hingis in the Tokyo final.

Later, third seed Mary Pierce of France takes on qualifier Sandra Nacuk of Yugoslavia, and fourth seed Julie Halard-Decugis of France looks to bounce back from an abdominal strain suffered last week in Oklahoma City when she encounters Ai Sugiyama of Japan.

Also, former world No. 1 Monica Seles of the United States, unseeded at a tournament for the first time since 1989, advanced to the second round with a 6-1, 7-6 (9-7) win over Silvija Talaja of Croatia. Seles returned from a broken foot last week and claimed the title at Oklahoma City.

Davenport is playing in her first event since capturing her third Grand Slam singles title at the Australian Open with a 6-1, 7-5 win over Hingis. Ranked No. 2 in the world, Davenport trails the top-ranked Hingis by only 494 points in the latest WTA rankings.

After personal problems forced Capriati out of tennis in the mid-1990s, she rededicated herself last season to the sport she took by storm in the early 1990s and won two tournaments.

Capriati, 23, continued her comeback at the Australian Open by advancing to her first Grand Slam semifinal in more than eight years before falling, 6-2, 7-6 (7-4) to Davenport.

Overall, Davenport has won three of four meetings with Capriati.

First prize at this hardcourt event is $87,000.
