Italian Francesca Schiavone, the 2010 French Open champion, had a much tougher time with her first-round opponent, but survived Jana Cepelova of Slovakia with a 5-7, 6-4, 6-4 victory.

Meanwhile, Slovakian veteran Daniela Hantuchova drubbed Bulgarian Tsvetana Pironkova 6-2, 6-4, and Romanian Simona Halep outlasted German slugger Sabine Lisicki 6-2, 3-6, 7-5, on Day 2.
