BEIJING (AP) -- Sixth-seeded Ana Ivanovic beat Casey Dellacqua of Australia 6-4, 6-0 Saturday to advance to the second round of the China Open.

Ivanovic was broken twice in the first set, but Dellacqua won less than half the points on her own serve as the Serb wrapped up the victory in little more than an hour.

In other first-round matches, 12th-seeded Timea Bacsinszky of Switzerland, Wang Qiang of China, Teliana Pereira of Brazil, and Svetlana Kuznetsova of Russia all advanced.

Bacsinszky rallied to beat Camila Giorgi of Italy 1-6, 6-4, 6-3, while Wang ousted American Varvara Lepchenko 6-2, 3-6, 6-2.
