New York, NY, USA, 5 September 2018 | tennis.com.au

Ash Barty is through to the US Open semifinals with partner CoCo Vandeweghe after winning her quarterfinal on Tuesday in straight sets.

Barty and Vandeweghe, the 13th seeds, brushed aside Dalila Jakupovic and Irina Khromacheva 6-2 6-3 at Louis Armstrong Stadium.

In the semifinals they could face top seeded Czechs Barbora Krejcikova and Katerina Siniakova, should the reigning Roland Garros and Wimbledon champions get past No.7 seeds Elise Mertens and Demi Schuurs.

Fellow Australian Sam Stosur is looking to join Barty in the semifinals; she and teammate Zhang Shuai will face Anastasia Pavlyuchenkova and Anastasija Sevastova in the quarterfinals on Wednesday.

Zhang is also through to the mixed doubles semifinals with another Aussie in John Peers.

Barty and Vandeweghe have enjoyed a stellar 2018 season; in just their second event together they won the Miami Open title and in May they advanced to the Madrid quarters.

As a duo they are 11-4 in 2018 and have not dropped a set in four victories at the US Open this fortnight.
