Andy Murray joined Katie Boulter and Cameron Norrie in winning US Open first-round matches on a productive day for the British players in New York.
Murray kept focus against combustible Frenchman Corentin Moutet to win 6-2 7-5 6-3 in an entertaining encounter.
Earlier, Boulter won her first main-draw match in New York with a 6-4 6-0 victory against France's Diane Parry.
Norrie, seeded 16th, also progressed by beating Russia's Alexander Shevchenko 6-3 6-2 6-2.
Murray, Boulter and Norrie are among six British players in action on Tuesday.
Jodie Burrage is looking to emulate Boulter by claiming her first US Open main-draw win in the women's draw, while Dan Evans and Jack Draper play in the men's event.
