Heather Watson matched her best Wimbledon singles performance by beating Wang Qiang to reach the third round.
The 30-year-old needed only one game to wrap up a 7-5 6-4 victory in a match halted by darkness on Wednesday.
World number 121 Watson, who has played in singles on every day of the tournament so far, will face Slovenian Kaja Juvan on Friday.
In the men's singles, fellow Briton Alastair Gray lost to Taylor Fritz.
The 24-year-old served for the second set but was eventually beaten 6-3 7-6 (7-3) 6-3 by the American 11th seed.
Gray saved two set points in the second-tie-break and thought he had saved a third, running away in celebration after stretching for a forehand volley, but a diving Fritz managed to get to the ball and send it back over the net.
