Britain's Katie Swan is one win away from the Wimbledon main draw after coming from behind to beat American Caty McNally in the second round of qualifying.
Swan, 22, trailed 5-3 in the final set but won four games in a row for a 4-6 7-6 (7-4) 7-5 victory at Roehampton.
She plays Australian Arina Rodionova on Friday for a spot in the grass-court Grand Slam, which starts on Monday.
Swan is the sole Briton left in women's qualifying after Naiktha Bains lost.
Bains, 23, was beaten 6-1 6-2 by Bulgarian eighth seed Tsvetana Pironkova, a former Wimbledon semi-finalist.
Later on Thursday, Britons Arthur Fery, 18, and Anton Matusevich, 20, play their final matches in men's qualifying.
