A resurgent Li Na took 4th seed Caroline Wozniacki out of competition in Sydney today, defeating her 2-6, 6-3, 6-2. Also leaving in the first round was 7th seed (that still sounds odd) Jelena Jankovic, who was taken out by qualifier (that still sounds odd, too) Agnes Szavay, 5-7, 6-1, 7-5.
Though those were the only two official upsets, there were some other upsets, and some other interesting results:
Flavia Pennetta made easy work of Sam Stosur, defeating her 6-3, 6-1.
Sabine Lisicki, after serving for the match at 5-4 in the third set, lost to Victoria Azarenka, who took the match 3-6, 6-2, 7-5. Lisicki hit 39 winners, including 11 aces, but made 75 unforced errors, including 9 double faults. Clearly, she is still all over the place.
Kimiko Date Krumm defeated Nadia Petrova 6-3, 5-7, 6-4.
8th seed Vera Zvonareva retired in her first set against Elena Vesnina because of--you guessed it--her right ankle. Zvonareva hurt the post-op ankle while playing an exhibition match in Hong Kong last week. She said that it became swollen because of the surgery.
And finally, Maria Jose Martinez Sanchez defeated Varvara Lepchenko, which means that she will play Serena Williams in the second round, and their matches get better as time goes on.
