Harriet Dart made it through to the second round of the US Open for the first time after breezing past Chloe Paquet in New York.
Dart is enjoying the best period of her career and after making it through to the third round at Wimbledon, she has followed it up by winning her first main draw match at Flushing Meadows.
The 26-year-old dropped just two games in a dominant performance which saw her win 6-1 6-2 and victory will see her ranking rise to a provisional career high of 66 in the world.
She will have her work cut out to repeat her Wimbledon feat as 13th seed Emma Navarro waits in the next round.
Dart was in control from the off, winning the first four games. Only a strong service game from Paquet denied the Brit from delivering a New York bagel.
Still, she took the first set and assumed control of the second set amid a run of five successive games.
Earlier, Jan Choinski became the first British casualty after falling to an agonising five-set defeat to Roberto Carballes Baena.
Choinski, ranked 276 in the world, had earned himself a 100,000 dollar (£75,730) payday by coming through qualifying to earn a spot in the main draw at Flushing Meadows.
And he looked to be heading for a swift exit as he found himself two sets and a break down to the world number 55.
But the British number 10 rallied to send it to a decider, only for Carballes Baena to regain control and earn a 6-2 6-3 5-7 6-7 (5) 6-3 victory.
