Welcome back to the Evening Standard's live coverage of the 2020 Australian Open.
It's been another terrific day of action as the competition enters its second week, and Simona Halep continued her run of not dropping a set with a comfortable triumph over Elise Mertens.
Elsewhere, Rafael Nadal came through a tough test in four sets against home favourite Nick Kyrgios to move into the last eight.
He will play Dominic Thiem, who produced an impressive display to down Gael Monfils in straight sets and reach the quarter-final for the first time, while Stan Wawrinka knocked out fourth seed Daniil Medvedev in a thrilling five-setter.
