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.

Serena Williams' comeback is ever more impressive. Every day the American is reminding us of how unprecedented tennis player she is, and even though she looked tired in her last match, a win is a win, and she is now only two matches away from winning her second straight title in only her fourth tournament since a year-long layoff which included a persistent foot injury and a serious problem with a blood clot in her lungs. Williams reached the semifinals of the Premier-level Rogers Cup by overcoming also unseeded Lucie Safarova 4-6 6-3 6-2. Victoria Azarenka will be Williams' next opponent. In the quarterfinals Azarenka ended the run of 135th-ranked qualifier Galina Voskoboeva, who eliminated Marion Bartoli, Flavia Pennetta and Maria Sharapova from the tournament.

The other semifinal will feature Samantha Stosur and Agnieszka Radwanska. Stosur took out Roberta Vinci, who scored major upset early in the tournament by beating world No.1 Caroline Wozniacki and later she defeated Ana Ivanovic. Radwanska reached the final four with a 6-4 6-3 victory over Andrea Petkovic. (photo courtesy of FIJI Water)

The Grand Slam-like field at the Rogers Cup is rapidly losing its biggest stars. Six major champions were in action on Thursday and only one survived – the mighty Serena Williams. The American returned only recently to competitive action and has already clinched a Premier-level title (Stanford) and is steadily making her way through the Toronto event.

Ana Ivanovic (Roland Garros 2008 winner), Li Na (Roland Garros 2011 winner), Petra Kvitova (Wimbledon 2011 winner), Francesca Schiavone (Roland Garros 2010 winner) and Maria Sharapova (three-time Grand Slam champion) all lost in straight sets in the third round of the Rogers Cup.

After defeating Alona Bondarenko 6-0 6-3 in the first round and Julia Goerges 6-1 7-6(7) in the second, Williams overcame Zheng Jie in an entertaining third round match for a 4-6 6-3 6-3 victory. The world No.82 Zheng, who is trying to improve her lost ranking, was two points from a 4-2 lead in the third set when Williams did her signature thing – brought her best game when it mattered the most.

Williams' opponent in the quarterfinals will be Lucie Safarova, who defeated eighth seed Francesca Schiavone 6-3 6-3 in the third round. Other quarterfinal pairs: Roberta Vinci vs. Samantha Stosur, Agnieszka Radwanska vs. Andrea Petkovic and Galina Voskoboeva vs. Victoria Azarenka. (photo courtesy of FIJI Water)

Li Na's French Open title propelled her in the world of sponsorships and fashion. As you may have noticed, I'm all for it, it's refreshing to have an Asian in the mix. The image above is from the Chinese edition of the Marie Claire magazine. Doesn't Li look stunning?

The 29-year-old is earning nice amounts of money by virtue of her tennis success and she finished 8th in the Forbes list of the highest-paid female athletes, however, the Chinese prefers spending her husband's money  "I still like to use my husband's credit card because I want to save my money," Li joked.

Italian Roberta Vinci is today enjoying the best day of her life having scored the biggest victory of her career by upsetting world No.1 Caroline Wozniacki in the Dane's opener at the Premier-level $2,050,000 Rogers Cup in Toronto. Wozniacki clinched last year's Rogers Cup title in Montreal by winning her semifinal and final match in one day.

After losing the first set against the 22nd-ranked Vinci, Wozniacki surged to a 5-1 lead, and just as it looked the match would go to the third set, Vinci won amazing six straight games to defeat the top seed 6-4 7-5.
