MELBOURNE (Reuters) - Serena Williams stormed into the quarter-finals of the Australian Open on Sunday with a gritty 6-4 2-6 6-4 victory over Belarusian Aryna Sabalenka.

The match was a big test for Williams, who was up against one of the few players on the women's tour capable of matching her power from behind the baseline.
