Heather Watson has been knocked out of the US Open in the first round, losing 6-4 6-4 to Alize Cornet.
The Briton was broken in the opening game in New York and although she saved three set points at 3-5, the Frenchwoman served out the set.
The 25-year-old twice recovered breaks in the second set but lost serve again at 4-4 before Cornet sealed victory in one hour and 36 minutes.
Watson has now lost all seven of her main draw matches at Flushing Meadows.
Cornet, ranked 46, faces two-time Wimbledon champion Petra Kvitova in round two after the Czech beat 2008 finalist Jelena Jankovic 7-5 7-5.
