The top-seeded Coetzer on Tuesday was upset in the second round by unseeded Russian Alina Jidkova, 6-3, 7-6 (7-5).

Playing in her first tournament since losing in the second round at last month's Pan Pacific Open, Coetzer received a first-round bye in this event.

Coetzer thought having the bye was a detriment.

"I felt a little rusty since I haven't played a tournament since Tokyo and by having a bye in the first round I think that puts you at a disadvantage since the other player has already played one match," Coetzer said. "She came out with a lot of confidence." Coetzer showed her rustiness, blowing a 5-3 lead in the second set as her record on the year fell to 5-4. The South African advanced to the fourth round at the Australian Open.

"She played very well and I had my chances," Coetzer said. "I gave away my chances, especially in the second set."

"This is definitely my biggest win for right now," said the 25-year-old Jidkova. "I was trying to attack every ball. I was nervous at different times in the match but I knew I had to fight for every ball. When I got nervous I just told myself to calm down and attack every ball. I was getting tired and I did not want to go to the third set."

Third-seeded Ai Sugiyama of Japan made it out of the second round with a 6-2, 7-6 (7-3) victory over countrywoman Shinobu Asagoe.

In a second-round match of unseeded players, American Jill Craybas defeated Aniko Kapros of Hungary, 2-6, 6-4, 6-4.

There also were three first-round matches on the women's side. American Erika De Lone ousted fifth-seeded Adrianna Serra Zanetti of Italy, 6-2, 6-4; seventh seed Jennifer Hopkins of the United States defeated Andrea Glass of Germany, 6-4, 6-4; and Yepn Jeong Cho of Korea bested American Sarah Taylor, 6-3, 7-6 (7-5).

On the men's side, third-seeded Jan-Michael Gambill, who lost his three previous matches this year, finally broke into the win column with a 6-1, 7-5 victory of Russian Nikolay Davydenko.

"It feels good to get the first win," said Gambill, who reached the quarterfinals or better in seven of his first eight tournaments in 2001. "I was on cruise control in the first set, but it was a tough second. I served big today and it helped me get through."

Sixth-seeded Jonas Bjorkman ensured that there would be a new winner at this year's event as he ousted defending champion Mark Philippoussis of Australia, 7-6 (8-6), 7-6 (7-1).

Eighth-seeded James Black advanced with a 6-3, 7-6 (7-4) victory over fellow American and former champion Michael Chang.

In matches of unseeded players, Justin Gimelstob defeated fellow American Mardy Fish, 6-3, 7-6 (7-4); and Andre Sa of Brazil got by Andrew Ilie of Australia, 6-2, 6-0.

The men's winner takes home $126,000, while the women's champion earns $27,000.
