Players in final no bearing on Open flag ban

Kubler and Hijikata eliminated the sixth seeds in the second round, but went to another level on Wednesday, trouncing top seeds Wesley Koolhof and Neal Skupski 6-3, 6-1 to make the semi-finals.

The Aussie pairing also saved a match point in the third round, so it is becoming a remarkable event for them, given neither is ranked inside the top 150 for doubles.

Nick Kyrgios and Thanasi Kokkinakis caused almost-daily headlines with their stunning run together at Melbourne Park last year, capped by their triumph over countrymen Max Purcell and Matt Ebden in the final.

The Kubler-Hijikata duo isn’t the only Australian combination performing well, with Marc Polmans and Olivia Gadecki advancing to the mixed doubles semi-finals.

Four on the trot

Aryna Sabalenka’s breakthrough Australian Open has qualified her for an exclusive club.

The 24-year-old fifth seed was once considered an underachiever – and she is still chasing a maiden major title – but her 6-3, 6-2 defeat of Donna Vekic makes her just the sixth woman to win her first four grand slam quarter-finals.

Sabalenka, who is into her fourth grand slam semi-final from her past six attempts, joins all-time great Chris Evert (48), Ann Jones (six), Billie Jean King, Elena Dementieva and Naomi Osaka (all four) in doing so.

Speaking of Billie Jean King, she and six other legendary members of the “Original Nine”, whose breakaway tennis circuit eventually became the modern WTA Tour, were at Melbourne Park on Wednesday.

King, Rosie Casals, Valerie Ziegenfuss, Peaches Bartkowicz, Kristy Pigeon, Julie Heldman, Nancy Richey and Australians Judy Dalton and Kerry Melville Reid courageously started their own professional tour, the Virginia Slims Circuit, in 1970.

They signed a symbolic $1 contract with the grander goal of championing equal rights for women.

“I feel very proud. I think we did a fantastic job. I don’t know whether we all realise what an effect we had,” Dalton said.

“We hoped that we would have a terrific effect, but I’m not sure we realised it would be as great as what it was.”

They will headline the AO Inspirational Series luncheon on Thursday.
