Zheng will play either the third seed Emma Navarro or eighth seed Amanda Anisimova in the semi-finals, before a potential final showdown with Australian Open champion Madison Keys or German qualifier Tatjana Maria, who stunned former Wimbledon winner Elena Rybakina earlier in the afternoon.

The vibes in London this week have been good for Emma Raducanu. She surpassed Katie Boulter to become the top-ranked British women's player and was powered by local fans through the first two rounds of the HSBC Championships at The Queen's Club.

Emma Raducanu cruised into the quarter-finals at the Queen's Club Championships with a 6-4 6-1 victory over Rebecca Sramkova on Thursday but fellow Britons Katie Boulter and Heather Watson were knocked out.
