TORONTO (AP) --  Qualifer Galina Voskoboeva of Kazakhstan beat No. 9 seed Marion Bartoli of France 6-3, 6-3 Monday in the first round of the Rogers Cup.

Bartoli struggled with her serve throughout the match, giving away four double-fault points, while Voskoboeva capitalized on her opportunities by winning four of her six break points.

"It was a day when nothing was working,'' Bartoli said. "I tried my hardest but I committed so many mistakes it was hard to win. I was not feeling the ball and my legs were not moving. I was late on everything and committing a lot mistakes, especially on my backhand.''

Bartoli was making her eighth appearance at the Rogers Cup and first since a first-round defeat in 2009 when she lost as the 13th seed to Ukraine's Alona Bondarenko.

"Something is not going well for me here in Toronto,'' Bartoli said. `"I don't know if it is the surface or the humidity or something, but it's been a two-year gap and it's the same kind of match.''

Romanian Simona Halep - another qualifer - rallied to upset 12th-seeded Svetlana Kuznetsova of Russia 4-6, 6-4, 6-3. The 15th-ranked Kuznetsova had 50 unforced errors to send Halep to the second round in her Rogers Cup debut.

In other matches, 10th-seeded Australian Samantha Stosur opened with a 4-6, 6-2, 6-3 victory over Japan's Ayumi Morita; China's Jie Zheng defeated Italy's Alberta Brianti 6-2, 6-1; the Czech Republic's Lucie Safarova downed Slovakia's Polona Hercog 6-3, 4-6, 6-3; Russia's Nadia Petrova ousted Australia's Jarmila Gajdosova 6-1, 6-2; and Hungary's Greta Arn upended the Czech Republic's Klara Zakopalova 6-3, 6-1.
