MELBOURNE, Australia>> 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 lost the 2024 decider at Melbourne Park to Aryna Sabalenka and went on to win the Olympic gold medal in Paris and finish runner-up at the WTA Finals in a breakout season.

But her first tournament of the year ended in a 7-6 (3), 6-3 loss on John Cain Arena against 36-year-old Siegemund, who attacked from the first point and put Zheng off her game.

Zheng needed a change of shoes early in the second set, got a time warning on her serve from the chair umpire — she said she couldn’t clearly see the clock — and was worried about some minor issues which sidelined her before the Australian Open.

“I feel maybe today is not my day. There’s a lot of details in the important points. I didn’t do the right choice,” Zheng said.

Sabalenka, the two-time defending champion, extended her run to 16 wins at Melbourne Park by winning the last five games to beat No. 54-ranked Jessica Bouzas Maneiro 6-3, 7-5.

No. 7 Jessica Pegula had a 6-4, 6-2 win over Elise Mertens to reach the third round.
