Great Britain's Harriet Dart has moved into the second qualifying round at the US Open by beating American Jamie Loeb 6-2 7-6 (7-3).
Dart, 23, reached the third round of Wimbledon in July and needs to win two more matches to qualify for the main draw of the US Open for the first time.
She plays another American, Hailey Baptiste, 17, next at Flushing Meadows.
James Ward reached the second qualifying round in the men's event by defeating China's Zhe Li 7-6 (7-5) 6-3.
Ward, 32, now faces Argentine Marco Trungelliti in New York.
However, fellow Britons Heather Watson, Katie Swan and Jay Clarke lost in the first round of qualifying.
Watson, 27, had played in the first round proper every year since 2011, but will not be in the main draw this year after losing 6-4 6-2 to Georgia's Mariam Bolkvadze, a player 101 places below her in the world rankings.
Swan, 20, was beaten 6-3 6-3 by American Katrina Scott while Clarke lost in men's qualifying. He took the first set on a tie-break against another home player, Mitchell Krueger, before going down 6-7 (2-7) 6-4 6-4.
