Top seeds Sania Mirza and Martina Hingis extended their amazing winning juggernaut to 34 matches, downing 12th seeds Anna-Lena Groenefeld and Coco Vandeweghe 6-2, 4-6, 6-1, to enter the women’s doubles semi-finals. The pair, dubbed SanTina by their fans, took one hour 38 minutes to complete the victory against their German-American opponents at the Margaret Court Arena.

The match was intensely contested with fortunes swaying both ways. Sania-Martina won five of the eight break points to turn the tie in their favour, even though they hit fewer winners (22 to 29).

They made up for that blip by committing fewer unforced errors (16 to 25) and won 83 points, 23 more than their challengers.

The Indo-Swiss pair, ranked No.1 in the chart, will take on 13th seeds Julia Goerges and Karolina Pliskova next. Goerges-Pliskova beat American duo of Vania King-Alla Kudryavtseva 6-2, 6-4 in the quarter-finals.
