Aryna Sabalenka's Australian Open title defence remains firmly on track after the world No.2 breezed into the quarter-finals of the Brisbane International.
Unlike men's Melbourne Park king Novak Djokovic, who suffered a shock setback in Perth, Sabalenka extended her winning streak in Australia to 13 matches with a 6-1 6-0 rout of China's world No.33 Lin Zhu at Pat Rafter Arena.
