But vondrousova

Marketa Vondrousova: Wimbledon champion Marketa Vondrousova crashed out of the Australian Open on Monday after a straight sets defeat to qualifier Dayana Yastremska in the first round.

The world No. 7 was completely outplayed by an aggressive Yastremska of Ukraine, who ran out with a comfortable 6-1, 6-2 victory in 76 minutes, reports Xinhua.

Vondrousova had withdrawn from the Adelaide International last week due to a right hip injury, but did not show any visible signs of distress. The Czech had started her season with a three-set loss to China's Zheng Qinwen at the mixed teams United Cup.
