In 1999, Hingis was shocked by Dokic, 6-2, 6-0, in the first round at Wimbledon. At the time, the women's world No. 1 was coming off an emotional loss to Steffi Graf in the final of the French Open and had a temporary split from her coach and mother Melanie Molitor. Hingis had beaten the Australian teen at the Australian Open that year en route to the title.

After a disappointing semifinal loss at this year's U.S. Open, Hingis bounced back in impressive fashion last week and captured the Porsche Tennis Grand Prix at Filderstadt, Germany. She dropped just 10 games in four matches to capture her fifth title of the year and improve her season record to 62-9.

A winner of 32 career singles titles, the 20-year-old Hingis has never won a tournament in her homeland, although she has come close with runner-up showings here in 1996 and 1999. With a title this week, she could surpass reigning Wimbledon and U.S. Open champion Venus Williams for the WTA Tour lead.

Williams, the defending champion, was scheduled to compete this week but decided to stay in the United States and return to fashion school.

Dokic, whose own coach -- father Damir Dokic -- has been banned from attending tournaments due to disorderly conduct at several tournaments, defeated Emmanuelle Gagliardi of Switzerland, 6-3, 6-0, in the first round on Monday.

Dokic's father made headlines at the U.S. Open when he was kicked off the grounds of the National Tennis Center after exhibiting abusive behavior in the players' lounge over the price of salmon.

But the younger Dokic shook off the distraction and reached the fourth round before losing to Serena Williams. She fell to Monica Seles in the bronze medal match at the Olympics and to Serena Williams again in the quarterfinals of last week's event in Tokyo.

Jennifer Capriati is the only other seeded player in action today as the fifth-seeded American squares off against Russian teenager Lina Krasnoroutskaya in a first-round match. Capriati owned an early break but Krasnoroutskaya rallied to take the first set, 7-5. They are on serve in the second set.

Also today, Bulgarian Magdalena Maleeva improved to 13-5 lifetime at this event with a 6-7 (5-7), 6-2, 7-6 (7-4) victory over Belgium's Dominique Van Roost. Maleeva, who captured the title in 1994, will battle third seed Nathalie Tauziat of France in the second round.

Barbara Schett of Austria routed Elena Likhovtseva of Russia, 6-0, 6-1, to advance to a second-round encounter with No. 5 Amanda Coetzer of South Africa.

In addition, Sabine Appelmans of Belgium battles Ai Sugiyama of Japan.

First prize at the hardcourt event is $166,000.
