Sania Mirza and her Chinese partner Su Wei Hsieh Hsieh were knocked out today in the second round of the Australian Open women's double. They were defeated by an unseeded pair of Gabriela Dabrowski and Alicja Rosolska. Struggling to find her rhythm from the start, Sania, who recently reached her career best doubles ranking of No.5 for the second time, looked out of sorts and failed to combine with Hsieh as they went down 7-6, 6-4 against the unseeded Canadian-Polish pair.
