Second seed Alfie Hewett and fellow Briton Gordon Reid reached the semi-finals of the men's wheelchair singles event at the US Open, while Jordanne Whiley progressed in the women's draw.
French Open champion Hewett defeated Frenchman Nicolas Peifer 7-5 6-2 and will face Argentine Gustavo Fernandez.
Tokyo 2020 Paralympic bronze medallist Reid beat Dutchman Tom Egberink 6-1 6-4 and meets top seed Shingo Kunieda next.
Meanwhile, Whiley overcame Japan's Momoko Ohtani in three sets.
Ohtani won the second set to level the match, but Whiley responded to win 6-1 5-7 6-3 and set up a women's semi-final against Japanese second seed Yui Kamiji - the Briton's doubles partner - or South Africa's Kgothatso Montjane.
Five-time Grand Slam singles champion Hewett - a two-time winner at the US Open - edged a tight first set before recording four breaks of serve on his way to sealing the second against Peifer.
Should he and doubles partner Reid win their respective semi-finals, it would set up a repeat of last week's Paralympic bronze medal showdown - a match Reid described as "the most difficult" he has played.
