World No 1 Aryna Sabalenka said she still had room for improvement after a second dominant win in the Brisbane International on Thursday.

Sabalenka was pushed at times by 36-year-old Sorana Cirstea but was never really troubled by the Romanian as she notched a 6-3, 6-3 win to reach the quarterfinals of the season-opening tournament.

The Belarusian will next play Madison Keys, the American who beat her in last year’s Australian Open final.

Keys came back from a set and a break down to overcome Russia’s Diana Shnaider in a three-hour marathon 6-7 (5/7), 7-6 (7/5), 7-6 (7/4).
