Kaia Kanepi on Monday rallied from a set down to upset second-seed Aryna Sabalenka to secure her maiden Australian Open quarterfinal appearance.
The Estonian needed two hours and 19 minutes to overcome a late, fierce resistance from the Belarusian for a 5-7, 6-2, 7-6 victory.
The world No. 1 barely clinched the first set on the strength of a break in the 12th game. EFE
