The first round concluded on Wednesday, and seventh-seeded Italian Roberta Vinci was a 6-4, 6-4 winner over Simona Halep of Romania.

Anabel Medina Garrigues, on the other hand, was a opening-round victim. The eighth-seeded Spaniard was dismissed by French wild card Pauline Parmentier 2-6, 6-3, 6-3.

Additional first-round wins came for Americans Bethanie Mattek-Sands and Christina McHale, Czech Klara Zakopalova, Romanian Monica Niculescu and Belgian Yanina Wickmayer.
