Elena Baltacha has been knocked out of the Strasbourg International in the first round, losing 6-4 6-0 to Stephanie Foretz Gacon.
The Frenchwoman, currently ranked 19 places lower than her opponent, took 72 minutes to secure victory on home soil.
Baltacha is currently 67th in the world and without a WTA tour win since March.
The disappointment comes just three days after the 28-year-old British number one reached the semi-finals of the ITF Sparta Prague Open.
But she failed to take her good form forward, just a week before the start of the French Open.
