Australian Open: Aryna Sabalenka defends tennis title with stunning performance

Aryna Sabalenka completed a ruthless defence of her Australian Open title by beating first-timer Zheng Qinwen in the final.

The world number two lifted her first grand-slam trophy at Melbourne Park 12 months ago and has been untouchable this fortnight. She did not drop a set in seven matches and defeated Zheng 6-3 6-2 to become the first player since countrywoman Victoria Azarenka 11 years ago to claim back-to-back titles.

Zheng, who had not had to face a top-50 player through the first six rounds, had hoped to emulate the watching Li Na and claim the title for China a decade on.

But the 21-year-old, the 12th first-time slam finalist in the women’s game in the last three years, was up against it from the start and Sabalenka wrapped up victory in only 76 minutes despite a brief disruption from pro-Palestine protesters.

Zheng had won just five games in their only previous meeting in the quarter-finals in New York last summer, and her hopes of doing better were hit by a disastrous start to the second set, serving three double faults in the opening game.
