MELBOURNE, Australia (AP) — Distracted by a time penalty and unable to counteract No. 97-ranked Laura Siegemund's aggressive approach, Zheng Qinwen'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.

Defending champion Aryna Sabalenka held on for a tough second-round win at the Australian Open on Wednesday, but last year's finalist Zheng Qinwen became the first Top 10 seed to fall this week.
