Angelique Kerber produced a superb performance to beat Maria Sharapova and confirm herself as a title contender at the Australian Open.
The German 21st seed won 6-1 6-3 in the much-anticipated night-session clash between the only two former champions left in the draw.
She needed just 64 minutes to see off Sharapova, breaking serve five times.
Kerber, the 2016 winner, will play Agnieszka Radwanska or Su-Wei Hsieh in the fourth round.
