Ash Barty will be Australia’s top seed at the US Open if she wins her battle with a viral illness that forced her out of the Connecticut Open this week.

The Australian No.1 has been seeded 18th in the women’s draw with compatriot Daria Gavrilova eight spots below, while Nick Kyrgios is the 30th men’s seed for the year’s final Grand Slam which starts on Monday in New York.

Barty, who is seeded directly below the Williams sisters, pulled out of the Connecticut event due to sickness on Sunday.

The world No.17 has been in solid form, winning eight of her last 11 matches on hard courts.

Barty’s only blemishes have been her third-round elimination from Wimbledon last month and two losses to world No.1 Simona Halep – in a semi-final at the Canadian Open in Montreal and then in the round of 16 in Cincinnati last week.

Gavrilova has been in fine form in Connecticut, where she’s vying to defend her sole WTA title.

The world No.24 has made it through to the final 16 after beating Romania’s Irina Begu 6-2 6-1 on Sunday.

Kyrgios, the only seeded Australian in the men’s draw, narrowly missed a spot in the Cincinnati quarterfinals last week to world No.3 Argentina’s Juan Martin del Potro.

Kyrgios joins James Duckworth, Alex de Minaur, Matt Ebden, John Millman, Jordan Thompson and wildcard Jason Kubler in the men’s singles event.

Exciting youngsters Thanasi Kokkinakis, Alex Bolt, Marc Polmans and Max Purcell are contesting qualifying this week.

Meanwhile, rising 20-year-old Lizette Cabrera won an eight-strong playoff to secure Australia’s reciprocal wildcard into the women’s singles main draw.

There she joins Barty, Gavrilova, former champion Sam Stosur and Ajla Tomljanovic.

Arina Rodionova, Destanee Aiava, Jaimee Fourlis and Olivia Rogowska are hoping to qualify.
