Maria Sharapova blasted past Romania’s Sorana Cirstea to reach the third round of the China Open on Wednesday.
The second-seed Russian cut down on the serving problems she had suffered earlier in the tournament as she secured a 6-2, 6-2 win.
The next opponent for Sharapova, 25, is Slovenian qualifier Polona Hercog, who battled past Russia’s Ekaterina Makarova 7-6(5), 3-6, 7-6(3).
The women’s draw lost both of its remaining Serbians as Ana Ivanovic and Jelena Jankovic lost in the third round.
Ivanovic, seeded 11th, was upset by world No. 69 Romina Oprandi of Switzerland 6-4, 6-3, and criticized herself for making too many mistakes.
"I got to pretty much all of the shots, but it was the unforced errors that made a big difference today," Ivanovic said on the WTA website.
Oprandi will face either world No. 1 Victoria Azarenka or Russian qualifier Elena Vesnina in the quarterfinal.
Carla Suarez Navarro toppled Jankovic in straight sets to beat her second big name in Beijing after an earlier defeat of Petra Kvitova.
Jankovic was 5-2 up in the first set before the Spaniard stormed back to snatch a 7-5, 6-4 victory.
In the quarters, world No. 46 Navarro will encounter either ninth seed Marion Bartoli of France or Germany’s Julia Goerges.
The men’s draw saw another seed exit as Ukraine’s Alexandr Dolgopolov was upset by Jurgen Melzer of Austria.
Dolgopolov, seeded sixth, dominated the second set but was swept aside in the decider as he lost 7-6(9), 2-6, 6-1.
Melzer, ranked 37th in the world, will face either top seed Novak Djokovic or Argentina’s Carlos Berlocq in the quarterfinal.
