"It was a really tough match,” said Miyazaki. “Eden and I have played each other many times. We are about the same age, so we have played since juniors. I'm glad to have got through.

“It is more nerve-wracking playing against a fellow Brit as we know each other so well. Having four British girls through to the quarter-finals is great."

Lacy – who has played with her quarter-final opponent Miyazaki in the LTA County Cup – received a walkover against Sachia Vickery.

Swan was first out on Centre Court against Oceane Dodin – however, with the Brit leading 5-3, Dodin was forced to retire with an injury. Swan will face top seed Tatjana Maria in the next round, who narrowly defeated Dart 6-4, 6-7(5), 6-4.

"It's tough to win that way," Swan commented after the match. "I feel really bad for my opponent that she had to stop because of a knee injury. I thought up until that point that I was playing pretty well. In some ways, it's good that I have more time to recover ahead of tomorrow. I am taking the positives from it. It looked like quite a bad injury. I hope she is not out for too long."

There was also good news for the British women in the doubles as Alicia Barnett and Olivia Nicholls booked their place in the final against fourth seeds Sophie Chang and Yanina Wickmayer.
