Serena Williams extended her winning streak to ten matches by defeating Victoria Azarenka 6-3 6-3 in the semifinals of the Rogers Cup. In her second straight final Williams will face Samantha Stosur.

The fourth-seeded Azarenka reached the semifinals having lost just six games, but Williams is in her Grand Slam-winning form ahead of the US Open. The American won eight of the last 11 points in the first set and 16 of the last 19 points in the second.

Samantha Stosur fell out of the Top 10 on Monday but with a 6-2 5-7 6-2 victory over Agnieszka Radwanska in the semifinals of the Rogers Cup the Australian will regain the spot. Radwanska was on a nine-match winning streak, having won Carlsbad, and at the Rogers Cup she hadn't dropped a set all week.

Monday at the Rogers Cup was a bad day for seeded players, as only one advanced and three of the other four fell to qualifiers in their opening matches.

The first in action was the winning seed, Samantha Stosur, but even her victory came only after she lost the first set 6-4 to Ayumi Morita. Final score: 4-6 6-2 6-3.

No.9 seed Marion Bartoli had won 19 of her last 23 matches, including her Eastbourne title, and had a perfect 4-0 head-to-head record against Galina Voskoboeva, but in the first round of the Rogers Cup the Kazakh qualifier was better and took Bartoli out 6-3 6-3. It is Voskoboeva's first Top 10 victory and at the recent Baku Cup she played her first WTA semifinals. Read more »

Both last year’s finalists were in action today. Defending champion Francesca Schiavone had an easy progress into the fourth round, as her opponent Peng Shuai retired with breathing problems at 6-3 1-2 (Schiavone won the first set). However, last year’s runner-up Samantha Stosur bowed out to unseeded Gisela Dulko – this match-up suggested a possible upset, especially because their both previous encounters were close, and the 51st-ranked Dulko recorded a 6-4 1-6 6-3 victory this time.

Maria Sharapova has positioned herself among the favorites for the 2011 French Open, the only Grand Slam the 24-year-old Russian still hasn’t won, by following up her win over world No.1 Caroline Wozniacki in the Rome semifinals with a 6-2 6-4 defeat of last year’s French Open runner-up Samantha Stosur.

When Sharapova is in a good tennis period, it’s a joy to watch her, her determination and focus combined with her powerful game produce a lot of winners that can’t leave you emotionless. I’m really looking forward to her shaking up the draw at the French Open. Not to mention that her fiancé’s engagement from the stands is really cute, it makes Sharapova’s wins even more moving.
