Zheng Qinwen, last year’s beaten Australian Open finalist, became the highest seed to fall so far in this year’s tournament after she was stunned by world No. 97 Laura Siegemund in the second round.

Distracted by a time penalty and unable to counteract No. 97-ranked Laura Siegemund's aggressive approach, Qinwen Zheng's loss in the second round Wednesday fell a long way short of last year's run to the Australian Open final.

Zheng Qinwen is out of the Australian Open after a shock defeat to Germany’s Laura Siegemund. Zheng, the No. 5 seed and last year’s beaten finalist, lost 7-6(3), 6-3 after her serve unraveled in the fourth game of the second set.
