Sixth seed Dmitry Tursunov, playing in his home contest, beat France's Julien Benneteau 6-3 7-6 (7/1). In the women's draw, Marion Bartoli kept up her pursuit of a place in the end-of-season WTA Championship with a 6-1 6-1 victory over Ksenia Pervak of Russia.
The Frenchwoman, seeded third, can qualify to play in Istanbul by winning the contest following yesterday's exit of second seed Agnieszka Radwanska. Sixth seed Svetlana Kuznetsova saw off Tsvetana Pironkova 7-5 7-5, while Dominika Cibulkova, seeded eighth, battled past Klara Zakopalova 7-6 (7/5) 6-2. The unseeded Elena Vesnina higher with a 6-3 6-4 victory over fellow Russian Ekaterina Ivanova.
