London, July 9: Indo-Swiss tennis pair of Sania Mirza and Martina Hingis came out with a clinical performance to enter the women's doubles semi-finals of Wimbledon here.

The top seeds needed only an hour and 19 minutes to win 7-5, 6-3 in a quarter-final tie against ninth seeds Australia's Casey Dellacqua and Kazakhstan's Yaroslava Shvedova on Court 3 of the All-England Club on Wednesday.

Sania and Martina started off their campaign on an aggressive note, winning 20 of 27 first serve points. But Dellacqua-Shvedova came back strongly by winning a break point. However, that didn't help their cause as the top seeds were too strong to break their opponents twice that led them to take the first set 7-5.

The second set saw the top seeds play more aggressively for their quest of the semis berth. The pair broke their opponents once and a double fault by Dellacqua-Shvedova made it easy for the Indo-Swiss combine to win the set 6-3 and advance to the last four.

Sania and Martina next face United States duo of Raquel Kops-Jones and Abigail Spears for a spot in the final.
