Toronto - Serena Williams won the WTA Rogers Cup title Sunday, beating Samantha Stosur 6-4, 6-2 to hammer home her credentials as a US Open favourite when the last Grand Slam event of the season starts in two weeks' time.
Williams hammered nine aces and won 89 percent of her first serve points in beating the Australian in straight sets at the $2.05 million hard-court tournament, two weeks after winning the Stanford title.
"Eight months ago if there was only one tournament I wanted to win, it was Toronto," Williams said. "For whatever reason, I really wanted to win this event. Just going through so much and being able to win is even more amazing."
It is her first back-to-back title in three years, the 39th of her career and 11th win in 11 matches on the US hard-court swing this summer.
Williams, who turns 30 next month, is currently ranked 80th in the world and was competing in just her fourth tournament since being sidelined for a year by injuries and illness.
Her win over Stosur took just 77 minutes as she played six matches in six days in Toronto and served notice that she is returning to form just ahead of the 2011 US Open.
"I consider myself a favourite to just do what I can do best, if that means winning the US Open, obviously I want to," she said. "I went through a lot of things physically and mentally and emotionally, and going through so much, I'm just taking it one day at a time and just going with it."
Williams broke Stosur's serve to go up 5-4 in the first set. She would break Stosur twice more in the second set before clinching the victory with a blistering ace.
Sunday's victory was her biggest since winning her fourth Wimbledon crown in 2010.
She was injured shortly after capturing that Wimbledon title, cutting her foot in Germany on a piece of glass and underwent two operations.
She then spent 20 weeks in a cast and walking boot.
In February, she was diagnosed with blood clots in her lung, and didn't start practising again until April.
Asked if she ever had any doubt during her long break whether she would be able to return to winning, Williams said, "Never. Never once. No."
Williams is projected to rise to No. 31 in the world when the next rankings list comes out.
Toronto rapper Drake was in the crowd at Rexall Stadium to watch Williams who shot down speculation they are dating.
"Oh man, really?" Williams said. "So much speculation. It's unbelievable. Shocking, really. It's too much. It's really too much. We're really good friends. I guess you can't be too close of a friend nowadays."
Williams, who grew up in the crime-ridden, drug-plagued south Los Angeles suburb of Compton, also had her parents, including her dad and coach Richard, in the crowd.
Stosur, who is seeded 10th, was seeking her third career title.
Stosur, of Gold Coast, Queensland, lauded Williams for the way she has handled herself during the comeback.
"She makes it look very easy, and it's not that easy to just come back on tour and win two events in your first four tournaments," Stosur said. "I think she's playing very well. To win a tournament like this, you have to be playing well."
