ARYNA SABALENKA has her sights on a second straight Australian Open title after a successful revenge mission against Coco Gauff today.

Gauff denied Sabalenka a second grand slam title of the year with victory in the US Open final last summer, but her winning run at the majors came to an end with a 7-6 (2) 6-4 defeat under the roof on Rod Laver Arena.

Sabalenka will now be a big favourite to successfully defend her title at Melbourne Park tomorrow when she takes on first-time slam finalist Zheng Qinwen, who defeated Dayana Yastremska 6-4 6-4.
