Harriet Dart edged out No 32 seed Katie Boulter 4-6, 6-1, 7-6 (8) to move into the third round of Wimbledon at the All England Lawn Tennis and Croquet Club in London on Thursday.
Boulter, the British No 1, had won six of her seven previous matches against Dart, the British No 2.
Dart, ranked No 100, will play Chinese Xinyu Wang next – reaching the third round of a Grand Slam for only the second time, following Wimbledon 2019 where she lost at that stage to Ash Barty.
Harriet Dart won against Chinese qualifier Zhuoxuan Bai (6-4, 6-0) in the previous round of The Championships.
In the first round of The Championships, Boulter, ranked No 29, defeated German Tatjana Maria (7-6 (6), 7-5).
