Meanwhile, Slovakian qualifier and WTA newcomer Anna Schmiedlova ousted fifth- seeded Frenchwoman Alize Cornet 6-3, 6-0.
Also on Day 2, Dutchwoman Kiki Bertens whipped Spaniard Lara Arruabarrena- Vecino 6-1, 6-1; Israeli lucky-loser Shahar Peer outlasted Bulgarian Tsvetana Pironkova 5-7, 7-6 (7-4), 7-6 (7-4); Romanian Irina-Camelia Begu overcame France's Mathilde Johansson 5-7, 7-6 (7-5), 6-1; Luxembourg's Mandy Minella came back to beat Serb Vesna Dolonc 3-6, 7-6 (7-4), 6-2; and Italian qualifier Maria Elena Camerin dismissed Slovak Jana Cepelova 7-6 (7-2), 6-3.
