PARIS (AP)—Australian Open finalist Li Na moved into the fourth round of the French Open on Saturday, beating Sorana Cirstea of Romania 6-2, 6-2.

The sixth-seeded Li, who this year became the first Chinese player to get to the final at a major tournament, will next face No. 9 Petra Kvitova.

Li has made at least the quarterfinals at the other three Grand Slam tournaments, but she has never progressed past the fourth round at Roland Garros.

Fourth-seeded Victoria Azarenka of Belarus also advanced, beating No. 30 Roberta Vinci of Italy 6-3, 6-2. Kvitova defeated Vania King of the United States 6-4, 6-2.

Later Saturday, Novak Djokovic was to return to the court to face Juan Martin del Potro. The pair started their match Friday, splitting the opening two sets, but it was suspended because of darkness.

Five-time champion Rafael Nadal was also scheduled to be on court, as was No. 7 Maria Sharapova.
