Notes: Insane field with two former No. 1s and an additional Slam champ all unseeded…The Top 3 seeds are current or former No. 1s…Tough opening-round matches are (5) Na vs. Tamira Paszek then the winner of Venus and (WC) Medina Garrigues, (3) Azarenka vs. Pavlyuchenkova, (11) Petrova vs. a qualifier then likely Kuznetsova, (16) Ivanovic vs. a qualifier then likely her Serb countrywoman Jankovic, (9) Stosur vs. the clay-savvy Suarez Navarro, and (2) Sharapova vs. a qualifier then likely Peng…No blue clay this year…Former champs in the field are Serena Williams (2012) and Kvitova (2011).

American women continue their surge during week two of the tennis season, while Bernard Tomic wins and Grigor Dimitrov falls.

Serbia will front two former No. 1s in Ana Ivanovic and Jelena Jankovic, while Russia counters with former world No. 2 Svetlana Kuznetsova, and Anastasia Pavlyuchenkova appearing in her fifth tie.

The Western & Southern Open features 18 of the Top 20 women’s players, with seeds Caroline Wozniacki, Vera Zvonareva, Victoria Azarenka, Maria Sharapova, Li Na, Petra Kvitova, Francesca Schiavone, Marion Bartoli, Andrea Petkovic, Samantha Stosur, Agnieszka Radwanska, Anastasia Pavlyuchenkova, Jelena Jankovic, Svetlana Kuznetsova, Ana Ivanovic, and Peng Shuai.

Li will next face No. 4 seed Victoria Azarenka, who advanced easily 6-2, 6-3 over unseeded Russian Ekaterina Makarova.

For just the third time in the Open Era (since 1968) none of the Top 3 seeds will be in the final eight of a Grand Slam.

“Solutions don’t come from heaven,” Nadal said. “I mean, you can’t change everything in one day. And you know what? I had not forgotten how to play tennis for a week, but I played better today.”

Was the pressure too much for Wozniacki, the clear favorite once Clijsters lost, who is still searching for a first Slam title?

“I know I’m not 100 percent,” Henin said. “I knew it before walking on the court. That’s why I say there are no excuses. I decided to play not being 100 percent. It’s been difficult in the last three days on my elbow and I just did everything that I could that it will be okay, but it wasn’t enough. I think Svetlana played a good match. She has all the credit today.”

Wozniacki thought that rather than Sharapova handing over the match with double faults and 36 unforced errors, the Russian’s sloppy play could be attributed to the Woz forcing her level of play.
