TOKYO (AP) -- Defending champion and top-seeded Martina Hingis advanced to the semifinals of the Pan Pacific Open with a 6-0, 6-2 victory over Anna Kournikova on Friday.

Hingis, the runner-up at the Australian Open last week, needed only 47 minutes to beat the fifth-seeded Russian for the seventh time in their eight career matches. The loss was on a clay court in the 1998 German Open.

Hingis had just two aces but didn't lose many points on her serve as she dominated the play throughout. She mixed her usual power with backhand slices, volleys and soft, angled shots on the synthetic carpet court of the Tokyo Metropolitan Gymnasium.

``I played very well and was very focused today,'' Hingis said. ``If I win one or two points in the beginning, that's very important. Today, I was just cruising through the match after that.''

Hingis' next opponent will be Chanda Rubin, a 6-4, 6-4 winner over Amanda Coetzer.

``Chanda had a good win yesterday against (Alexandra) Stevenson, and she's playing very good here,'' Hingis said. ``She's a quick player and has a very good forehand.''

Hingis has beaten Rubin in four of six matches.

Rubin had a scare in the second set against Coetzer, when she was broken for a 4-4 tie. But Rubin broke back the next game with some sharpshooting down the lines and then held her own serve.

``I wasn't worried. I was a bit annoyed to drop my serve,'' Rubin said, recalling the crucial moment in that second set. ``Then I thought I rushed the game a little bit and let it slip away.''

Against Hingis in the semifinals, Rubin said: ``I feel very good going into the match. I feel like I'm playing very well, hitting the ball well. She's always tough to play. I'll just try to do a little bit of the same things I did today, be a little more solid and see where I end up when it's all finished.''

In the other quarterfinals, Katarina Srebotnik beat lucky loser Lilia Osterloh of the 7-6 (6), 6-1, and Sandrine Testud ousted Nathlie Tauziat 7-6 (4), 6-0.
