However, there were plenty of shock results elsewhere in the women's draw, with ninth seed Vera Zvonareva the biggest casualty, the Russian going down 6-4 6-3 to Spanish wild card Garbine Muguruza Blanco.
Also departing the tournament are 18th seed Angelique Kerber, Lucie Safarova (27), Kaia Kanepi (31) and Nadia Petrova (32), who all lost in straight sets, while Monica Niculescu (28) was beaten in three.
