Teenager Ivanovic Shocks Mauresmo at WTA Sydney

"I beat her before (French Open), and that helped me out today as well," said Ivanovic, who finished 2005 at No. 16 on the WTA Rankings. "It was a really hot day and it was hard out there. I was really pleased I took the opportunities in the second set and managed to finish in two."

Mauresmo will now enter the Australian Open with an 0-1 record on the year.

"I probably would have needed at least one more match before playing her," Mauresmo said. "That made a big difference today."

Also melting down in the Sydney heat Tuesday was No. 3 seed Patty Schnyder, losing in three sets to Daniela Hantuchova.

Seeded winners on the day were (1) Kim Clijsters (d. (Q) N.Li), (4) Nadia Petrova (d. Russian countrywoman Kirilenko), (5) Justine Henin-Hardenne (d. (Q) Dushevina), (6) Svetlana Kuznetsova (d. Russian countrywoman Safina who retired with a foot blister), (7) Francesca Schiavone (d. (Q) Z.Yan), and (8) Nicole Vaidisova (d. (Q) Fedak), all in straight sets.

"I was struggling with the heat in the first set," said Clijsters who came to Sydney from an exhibition in Hong Kong. "My skin was burning even though I put lots of sunscreen on."

Scheduled for Wednesday are (6) Kuznetsova vs. Ivanovic, (5) Henin-Hardenne vs. (4) Petrova, (1) Clijsters vs. (7) Schiavone, and Hantuchova vs. (8) Vaidisova.
