Sam Stosur and China's Zhang Shuai have reached the women's doubles semifinals at the US Open.
It matches their career-best result as a team in New York, having also advanced to the final four together in 2018.
The No.14 seeds progressed with a 6-2 6-3 victory against Australia's Storm Sanders and American Caroline Dolehide in quarterfinal action today. They hit 24 winners and only faced a single break point against the No.10 seeds in the 81-minute match.
The impressive performance maintains 37-year-old Stosur's unbeaten record in US Open women's doubles quarterfinal matches, improving her career record to six wins from six matches.
By making her sixth US Open women's doubles semifinal, Stosur further cements her position as one of Australia's most successful players in the Open era.
With 16 years between her first and current semifinal, Stosur has set a new Australian record for longest span between appearances.
While only one woman - Wendy Turnbull, who made seven US Open doubles semifinal appearances - has reached this stage more.
