French Open finalist Alexander Zverev overcame a spirited start by Australia’s Alexei Popyrin to reach the last eight.

The quarter-final line-up also includes Greece’s Stefanos Tsitsipas, Canada’s Felix Auger-Aliassime, Italy’s Lorenzo Musetti, Norway’s Casper Ruud and the USA’s Tommy Paul.

French Open women’s champion Iga Swiatek went through – having been tested in her quarter-final. She was leading 6-1 2-6 4-1 when the USA’s Danielle Collins retired in the deciding set.

Germany’s three-time Grand Slam champion Angelique Kerber’s career finally came to an end, after losing to China’s Zhang Qinwen 6-7 (4-7) 6-4 7-6 (8-6).

“I’ve achieved everything I dreamed of,” Kerber said.

“I was number one, won Grand Slams, won a [silver] medal in Rio, so what more could you want in the end?”

Kerber triumphed at the 2016 Australian and US Opens before claiming the Wimbledon title two years later.
