Sania Mirza and Jie Zheng moved into the semi-finals of the women's doubles at the US Open, scoring a straight sets victory over Su-Wei Hsieh and Shuai Peng, on Wednesday.
The Indo-China pair, seeded 10th, beat the fourth seeded Taipei-Chinese combine 6-4, 7-6(5).
They will next play eighth seeds Ashleigh Barty and Casey Dellacqua of Australia, who beat second second seeds Ekaterina Makarova and Elena Vesnina of Russia 6-2, 6-3
Mirza and Zheng, who bested sixth seeds Anna-Lena Groenefeld and Kveta Peschke 6-2, 6-3 in the third round, had little trouble against the fourth seeds en route to the last four.
In the match at the Louis Armstrong stadium, a single break was enough to give Sania and her Chinese partner the opening set.
It went on serve in the second before the Indo-Chinese pair did just enough, by securing a mini-break and holding serve thereafter.
For Sania, it will be her first semi-final appearance in New York, and fourth overall in a major tournament.
The Indian has now reached the last four stage in the women's doubles at all the four major tournaments.
She was a beaten finalist in the 2011 French Open, partnering Vesnina.
