British men's number one Cameron Norrie made light work of unpredictable Frenchman Benoit Paire as he started his US Open bid in style.
Seventh seed Norrie, 27, won the first set in 18 minutes before Paire improved to make a contest of the second.
But Norrie ran away with the third when Paire's level dropped again to win 6-0 7-6 (7-1) 6-0 in sticky conditions.
Norrie plays Joao Sousa or Mackenzie McDonald next as he aims to better his run to the Wimbledon semi-finals.
British number two Dan Evans, seeded 20th, starts against Czech Jiri Vesely on Tuesday, before Emma Raducanu - the nation's leading women's player - starts the defence of her title against France's Alize Cornet in the night session in New York.
