World No. 2 Angelique Kerber was sensationally bundled out of the Australian Open yesterday by a women playing the event for the first time, as Ashleigh Barty muscled past Maria Sharapova to make the quarter-finals.

The German Wimbledon champion was left stunned by American Danielle Collins who humiliated her 6-0, 6-2. Hometown hero Barty is also a surprise quarter-finalist after bringing Sharapova's drive to win a first Grand Slam since the 2014 French Open to a grinding halt 4-6, 6-1, 6-4. She will now meet Petra Kvitova, who beat unseeded American Amanda Anisimova 6-2, 6-1.
