Katie Swan is one victory away from a place in the French Open main draw after beating China's Wang Xiyu in the second round of qualifying.
The 20-year-old had posted one of the best wins of her career on Wednesday by knocking out second seed Jil Teichmann and recovered from losing the second set to love against Wang to triumph 6-4 0-6 7-5.
In the final round Swan, one of the lower-ranked players in the draw at 208, will take on Slovakia's Kristina Kucova.
There was heartbreak, though, for Heather Watson, who served for victory in the third set against Greek Valentini Grammatikopoulou and held two match points only to lose 7-5 6-7 (6) 7-6 (3).
Johanna Konta will play a qualifier in the first round of the French Open as she bids to continue her fine form on clay this season.
The British number one's superb run to the final of the Italian Open in Rome last weekend was particularly timely because it earned her a place among the 32 seeds in Paris.
As the 26th seed, Konta should have a good chance to claim her first main draw win at Roland Garros.
Surprisingly, Katie Boulter's name remained in the draw despite back problems that had been expected to rule her out for the entire clay-court season, and potentially grass as well.
Boulter drew 23rd-seed Donna Vekic from Croatia, while top-seed Naomi Osaka faces a treacherous route if she is to win a third consecutive slam title on a surface on which she is not yet totally comfortable.
The Japanese should beat Anna Karolina Schmeidlova in round one but would then face the winner of a blockbuster opener between Victoria Azarenka and former champion Jelena Ostapenko.
