Melbourne: World No. 1 pair of Martina Hingis and Sania Mirza got the better of Anna-Lena Groenefeld and CoCo Vandeweghe to cruise into the women’s doubles semi-final at the Australian Open, here on Tuesday afternoon.

Having won their first three matches at the Melbourne Park, the Indo-Swiss made the perfect start against No.12 seeds Groenefeld and Vandeweghe, winning the opening set in a brisk 23 minutes. However, their opponents came back strong in the second set to level the contest 1-1 by taking the second set 6-4. However, the top seeds steadied the ship, breaking twice to close out a 6-2, 4-6, 6-1 victory.

The result extends Hingis and Mirza's remarkable winning streak to 34 matches - a run stretching back to the end of last summer and bringing seven titles.
