Sveta and Vera first to final 4.

Two of Russia's best snapped up the first two semifinal berths at the Rogers Cup, as Svetlana Kuznetsova and Vera Zvonareva were in full flight in Quarterfinal Friday's afternoon session.

Kuznetsova, the No.11 seed, was the first into the final four, holding off a late surge from Zheng Jie to win, 6-1 6-3. Zheng closed from 0-3 to 3-4 in the second set but lost her serve at love and Kuznetsova served it out.

"Zheng is getting better and better. I used to beat her very easily and the last few times we've played it was harder," Kuznetsova said after the match. "I was a little bit lost for a while, but now I know what I have to do. Winning matches makes you a totally different player and now I know how to do it again."

Zvonareva, the No.8 seed, was down 6-2 3-2 to Kim Clijsters when she went on a tear against the No.5 seed, winning nine games in a row to win the second set and build a 5-0 lead in the third. Clijsters started a mini-comeback, winning two games in a row, but Zvonareva stuck with her and closed it out, 2-6 6-3 6-2.

The other two quarterfinals will take place in the night session, with No.2 seed Caroline Wozniacki facing No.6 seed Francesca Schiavone and No.10 seed Victoria Azarenka taking on No.17 seed Marion Bartoli.
