New York, NY, USA, 12 September 2015 |

Casey Dellacqua and Yaroslava Shvedova again had to battle hard, but they would not be denied.

The fourth seeds came through a near three-hour match to defeat the unseeded duo of Anna-Lena Groenefeld and Coco Vandeweghe 6-7(3) 7-5 7-5 to advance to the US Open women’s doubles final.

It’s their second major doubles final together after they reached the same stage at Roland Garros.

“It’s pretty cool,” Dellacqua said.

“We only started playing together in Madrid, which was in May, so to have made two Grand Slam finals since then in six tournaments together, I guess you could say we team up pretty well.”

Their match played out on Louis Armstrong Stadium at the same time Roberta Vinci was pulling off a stunning upset of world No.1 Serena Williams in the singles semifinals on nearby Arthur Ashe Stadium, which provided a small distraction.

“We were hearing everything also, and it was bit difficult, I think when the match finished, there was screaming a lot,” Shvedova said.

Added Dellacqua: “It was a big moment in our match, we could hear so much cheering going on.”

Yet they were able to focus, and close out their own victory.

The Aussie-Kazakh pairing have now been stretched to three sets in four of their five matches at Flushing Meadows this fortnight.

With their semifinal split over two days after rain washed out play late on Thursday afternoon, Dellacqua and Shvedova had led by a break in the first set yet only to see that advantage slip away

They also trailed by a break in the final set before rebounding.

“Today we knew we were going to expect some big serves, a big game,” Dellacqua said of the powerful Groenefeld and Vandeweghe.

“We just had to fight hard. There’s no other real way to describe getting through that match. It was just a matter of fighting hard together and getting through that one.

“This whole tournament for us has been a real fight.”

In the decider, they face a monumental hurdle in top-ranked duo Martina Hingis and Sania Mirza, the reigning Wimbledon champions.

“It’ll be really exciting,” Dellacqua said.

“I think the good thing for us is that we’ve actually played them before (at Wimbledon in July) … we know what to expect I guess.

“If we play our game and do what we do well, we can definitely trouble them.”

Dellacqua’s success continues a great second week at the US Open for Australia, with John Peers reaching the men’s doubles final and Alex De Minaur cutting a swathe through the boys’ singles draw.

> De Minaur into US Open semis

The West Australian, who will contest her sixth major women’s doubles final in the pursuit of her first winner’s trophy, said she was determined to enjoy the experience.

“There’s a lot of matches (at this tournament) we potentially could have lost,” Dellacqua said.

“But we just fought hard, and we’re here now and we’re in the final, so let’s enjoy it, enjoy the moment, play our best tennis, and see how we go.”
