Zvonareva had little trouble in her 6-2, 6-3 win over Lucie Hradecka in her first match of the clay court tournament. She is to face Magdalena Rybarikova in the round of 16. Rybarikova advanced with a 6-1, 6-3 win over Meghann Shaughnessy.
No. 4-seeded Katarina Srebotnik had the third "double bagel" of her career with a 6-0, 6-0 whitewashing of Yvonne Meusburger and seventh-seeded Klara Zakopalova, a Czech and so a local favorite, rolled with a 6-1, 6-3 win over Sara Errani.
Third-seeded Victoria Azarenka had her opening-round match postponed because of rain.
