Heather Watson was unable to prolong British interest in the French Open singles after losing her first-round match to France's Fiona Ferro.
Watson, 28, was the final Briton in the draws after five of her compatriots were beaten on the opening two days.
But the world number 58 lost 7-6 (7-4) 6-4 to Ferro, who is ranked nine places higher in the world.
Watson's defeat means she has not won a match since the professional game returned in early August.
The Guernsey player competed at a decent level against the in-form Ferro, but their contrasting form coming into the Grand Slam event in Paris appeared to prove decisive.
