Serena Williams blew away Francesca Schiavone 6-3, 6-3 and then complained about her game. The second-seeded American sets the bar high these days and to give away six games to an unseeded Italian player seems a little too generous for a French Open champion.

It was a day where the top seeds sat tight for another round while in the men's draw fractures appeared all over.

Jennifer Capriati also quietly advanced giving away just three games to Spain's Marta Marrero. Capriati, seeded three for the championships, set out her stall early in an aggressive display.

The first set, a tidy 6-2 was followed by an even more brusque 6-1 in a heavily one-sided display.

Of them all, Jelena Dokic had to work hardest for her win over Kevta Hrdlickova. After a blistering start where she took the set 6-0, Dokic then made a few mistakes in the first game of the second set and from there on things began to unravel.

As Hrdlickova sensed the fraying of Dokic's game, she seemed to grow, taking the second 6-4 and causing the seventh seed huge discomfort.

"She kept getting better and better and I was getting too defensive," said Dokic. "I was too tight and too nervous. You know when you lose the second set, no matter how good you played in the first, you know you're even."

Dokic, although going on to win the match with a final 8-6 set, knows that getting tight against players later in the tournament can only end in tears. Capriati and Serena Williams are in her side of the draw. "I'm not worried about that," she said. "I've done well here so you know I'm supposed to be in the quarters at least."

Also through are teenager Daniela Hantuchova, who defeated the Czech Republic's Martina Sucha 6-2, 4-6, 6-3, and Mary Pierce, who defeated seventh seed Sandrine Testud 6-3, 6-4.
