No.7 seed Angelique Kerber has advanced to the Australian Open quarter-finals for the first time with a 6-4 6-0 victory over fellow German Annika Beck.

After being down match point in her first-round encounter against Japan’s Misaki Doi, Kerber has built steadily through the tournament and can now look forward to a quarter-final encounter against either two-time Open champion Victoria Azarenka or Czech Barbora Strycova.

In nine previous visits to Melbourne Park, Kerber’s best efforts were reaching the fourth round in 2013 and 2014.
