Australian tennis star Ash Barty has landed her maiden grand slam title, teaming with American CoCo Vandeweghe to win a thrilling US Open women’s doubles final in New York.

Barty and Vandeweghe saved three match points to edge out second-seeded Australian Open champions Timea Babos and Kristina Mladenovic 3-6, 7-6 (7-2), 7-6 (8-6) in the first-ever women’s doubles grand slam final decided in a third-set tiebreak.

Barty’s triumph completes a memorable US Open for the Queenslander, also reaching the fourth round of the singles, marking the first time the former Wimbledon junior champion and WBBL cricketer had made the second week of a slam.

She also won the US Open Sportsmanship Award, recognising excellence in sportsmanship during the American lead-up events and the final grand slam of the season.

Barty is the seventh Australian to win the US Open women’s doubles title, joining four-times champion Margaret Court, Judy Tegart-Dalton, Wendy Turnbull, Hana Mandlikova, Rennae Stubbs and Samantha Stosur.
