Australian tennis star Samantha Stosur insists that missing the New Delhi Commonwealth Games would not be important to her, as she eyes one of the rarest feats in women's tennis.

Stosur's progression to the second week of the US Open for the first time has the French Open runner-up poised to qualify for next month's prestigious WTA Tour Championships in Doha.

It would be an opportunity for her to join Martina Navratilova, Martina Hingis, Jana Novotna and Lindsay Davenport as the only women ever to have won both the singles and doubles at the championships.

The 26-year-old has already secured two doubles crowns with American Lisa Raymond in 2005 and 2006.

"To be in the position that you might qualify (for the singles), or have a good chance of qualifying, it's definitely a goal so I'd absolutely love to be there," The Daily Telegraph quoted Stosur, as saying.

"Obviously you've got to play the right tournaments to get there. It's a bit of a shame with the Commonwealth Games conflicting, but that's the way it is," she added.

Stosur will face Russia's Elena Dementieva in her fourth-round US Open clash on Sunday. (ANI)
