Advancing to the quarterfinals was Slovak Jana Cepelova, who surprised eighth-seeded Annika Beck of Germany 7-6 (8-6), 6-4 in Tuesday's the lone second-round match.
Other opening-round winners included fifth-seeded Slovak Magdalena Rybarikova, seventh-seeded Frenchwoman Kristina Mladenovic, German Tatjana Malek, Brazilian wild card Beatriz Haddad Maia, Hungarian Timea Babos, and Spaniard Garbine Muguruza.
