MELBOURNE (Reuters) -Novak Djokovic fought off another feisty challenge to reach the third round of the Australian Open on Wednesday after women's champion Aryna Sabalenka made more serene progress and Ons Jabeur crashed out at the hands of a schoolgirl.
Top 10 seeds Coco Gauff, Barbora Krejcikova, Beatriz Haddad Maia, Jannik Sinner, Andrey Rublev and Stefanos Tsitsipas all got through their second-round contests in varying conditions as Melbourne lived up to its reputation for changeable weather.
