Harriet Dart was the first Briton to reach the third round at this year's Wimbledon after a battling performance against Brazilian Beatriz Haddad Maia.
Dart, 22, won 7-6 (7-4) 3-6 6-1 to set up an encounter with world number one Ashleigh Barty.
The Briton wobbled at times but kept a lid on her nerves to win back-to-back tour-level matches for the first time.
There are four more Britons in singles action on Thursday, including the country's number one Johanna Konta.
Wildcard Jay Clarke takes on 20-time Grand Slam champion Roger Federer, while British number two Cameron Norrie and Dan Evans are also playing.
