Qualifying losses for Brits
Daniel Cox has failed to join Andy Murray in this year's US Open men's singles draw after losing his first-round qualifier in New York on Tuesday.
The 23-year-old was on court for just 69 minutes as he slumped to a 6-3 6-3 defeat to Serbia's Filip Krajinovic.
Naomi Broady will not be keeping Heather Watson and Johanna Konta company in the women's singles draw after losing in straight sets to American Tornado Alicia Black.
The 24-year-old Stockport native, part of the qualifying draw at Flushing Meadows for the third consecutive year, would have approached her first-round qualifier full of confidence after winning three tournaments on the ITF circuit this year but lost 7-5 (8/6) 7-6 (7/2) in two hours and 16 minutes.
A trio of Brits will look to advance on Wednesday, with James Ward, Dan Evans and Daniel Smethurst all in action.
Ward, seeded 15th in qualifying, will take on Aldin Setkic, Evans has a tough task against the No 16 seed Jimmy Wang and Smethurst, the world No 256, has been drawn against Russia's Konstantin Kravchuk.
