Australian Samantha Stosur defeated 12th seed Russian Elena Dementieva to advance to the US Open quarter-finals early on Monday.

Stosur defeated Dementieva 6-3 2-6 7-6 (7-2) and set up a last-eight showdown on Wednesday (EST), where she will play against defending champion Kim Clijsters.

It was the latest finishing women's singles match in US Open history.

"I feel unbelievable right now. I think we both played a great match. We went for it and just gave it our best, so to have a match like that here's just fantastic. It's good to make history, I guess," The ABC Sport quoted an ecstatic Stosur, as saying.

"It's a great atmosphere out here. It was always going to be tough following the guys but whenever everybody stays around and cheers and supports us like that, it couldn't be any better," she added. (ANI)
