INDIAN WELLS, Calif. (AP) - Chanda Rubin, streaking shots down the line then attacking the net, stunned Martina Hingis with a straight-set victory Wednesday in the Evert Cup quarterfinals.

The unseeded Rubin, in what she called the best win of her career, ousted defending champion Hingis 6-3, 7-6 (7-2).

Rubin, ranked 26th in the world, stroked accurate shots from the baseline to keep the top-ranked Hingis scrambling from side to side, then frequently rushed forward to seal the point with a volley.

She fought back with two services breaks after Hingis took leads of 5-4 and 6-5 in the second set.

Hingis, who won two of the five events she had played this year and reached the final in another, seemed out of synch.

Rubin, of course, had a lot to do with that, including nailing many services returns within inches of the lines. Hingis won just five of her 21 second serves, and Rubin hit 29 winners in the match to Hingis' 10.

``I wanted to take advantage of her second serves, take the opportunity to start the point off aggressively,'' said Rubin, 23, who is 2-1 in career matches against Hingis, 18. ``I took a lot of aggressive hits at her serve.''

Hingis was impressed.

``I think she played an unbelievable match,'' said Hingis, losing for just the third time in 18 matches this year. ``I was always a step too late and too defensive.

``When I tried to come in, she would pass me with unbelievable shots.''

Rubin, whose highest world ranking was sixth briefly in 1996, was sidetracked by an injury to her right wrist early that year. She underwent surgery on her wrist in August 1996 and seems finally to be getting her game back in top shape.

Off to a solid start this year, she won her second career singles title with a victory at Hobart, Australia, and beat world No. 17 Conchita Martinez in the Evert Cup second round and No. 9 Amanda Coetzer in the third round.

Then she knocked off the top player.

``I definitely would say this is the best win of my career,'' Rubin said. ``She's No. 1 in the world, and the best player week in and week out.''

Hingis said: ``I think everybody knows that she always had this game, to be a top player. Since she had injuries, especially the wrist, it's been hard for her to come back. She was always tough to play.''

In second-round matches in the Newsweek Champions Cup, being played concurrently with the Evert Cup at the Hyatt Grand Champions Resort, defending champion Marcelo Rios defeated Cedric Pioline 7-6 (7-3), 6-1 and Richard Krajicek downed Jan-Michael Gambil 6-7 (3-7), 7-5, 7-5.
