Coming off an impressive second-round win on Wednesday, Hingis continues defense of her title against Kveta Hrdlickova of the Czech Republic.

Davenport, seeded second, looks to move one step closer to her first title since April when she meets qualifier Magdalena Maleeva of Bulgaria, who upset ninth seed Amanda Coetzer of South Africa on Wednesday.

Seeking her second straight singles title, reigning U.S. Open champion Serena Williams has a tough third-round opponent in No. 11 Anna Kournikova of Russia as the two teenagers square off tonight for the first time.

In other third-round action, third seed Conchita Martinez of Spain meets 10th seed Julie Halard-Decugis of France; seventh seed and two-time champion Arantxa Sanchez-Vicario of Spain faces No. 13 Jennifer Capriati of the United States, the 1991 winner; and eighth seed Sandrine Testud of France battles No. 15 Chanda Rubin of the United States.

Also, Silvija Talaja of Croatia goes against Anne Kremer of Luxembourg in a matchup of unseeded players. Kremer eliminated fifth seed Nathalie Tauziat of France in the second round.

One second-round match will be completed as No. 16 Amy Frazier of the United Sates and Gala Leon Garcia resume in the third set with Frazier leading, 3-6, 6-2, 4-3. The winner will take on sixth seed Anke Huber of Germany later today.

Hingis crushed qualifier Nadejda Petrova of Russia, 6-1, 6-3, on Wednesday.

Hingis has had mixed results in her first two summer hardcourt events. She reached the quarterfinals at the Acura Classic two weeks ago before falling to Williams last week in the semifinals.

The Swiss teen has won four titles this season, including the Ericsson Open on hard courts, and has reached the finals at three other hardcourt events, including the Australian Open.

Last year, Hingis ended Monica Seles' four-year reign at this event with a 6-4, 6-4 victory.

Davenport overcame a foot problem to pull out a three-set win over Belgian qualifier Justine Henin on Wednesday.

The 24-year-old Davenport failed to win each of the three summer hardcourt events in her home state of California. She lost to Serena Williams' older sister, Venus, in the final at Stanford, California three weeks ago. Davenport followed that with a second-round loss to Kournikova at San Diego before falling to Serena in Sunday's final of the estyle.com Classic in Los Angeles.

Davenport has won two titles this season, both on hard courts. One of those came at the Australian Open in January.

Serena Williams, seeded fourth, extended her winning streak to six matches with a convincing 6-1, 6-2 victory over Patty Schnyder of Switzerland on Wednesday.

The 18-year-old Serena Williams is trying to extend the dominance that she and her sister have displayed over the last six weeks. Venus Williams captured three straight events before Serena extended the sisters' streak to four with last week's triumph in Los Angeles.

This tournament began in 1892 and offers a $166,000 first prize.

It is the last year the event will be known as the du Maurier Open because of recently passed laws barring tobacco companies from sponsoring sports events. Next year it will be called the Roger's AT&T Canada Cup.
