Big-hitting world No.1 Sabalenka hasn't dropped a set and appears unstoppable as she chases a third Melbourne Park crown. Only Goolagong Cawley (1971-1977) and Hingis (1997-2002) have also reached at least four straight finals in the Open era. "I cannot believe that, honestly, and that's an incredible achievement - but the job's not done yet," the world No.1 said. The only time the indomitable world No.1 looked frustrated was when leading at 2-1 when she was called for hindrance for grunting after playing the ball. After Svitolina saved two set points on serve, Sabalenka sealed the advantage with a scintillating cross-court backhand winner.
