Britain's Johanna Konta continued her remarkable Australian Open run with a straight-sets win over China's Zhang Shuai in the quarter-finals.
The unseeded 24-year-old won 6-4 6-1 to become the first British woman to reach a Grand Slam semi-final since Jo Durie made the US Open last four in 1983.
Konta, ranked 47th, will next face German seventh seed Angelique Kerber.
Fellow Briton Andy Murray takes on Spain's David Ferrer in the men's quarter-finals later on Wednesday.
Konta powers through to semis
The British number one took full advantage of facing a quarter-final opponent who was also in uncharted waters, seeing off world number 133 Zhang in one hour and 22 minutes.
