Azahara Munoz upstaged home favourites Gwladys Nocera and Valentine Derrey to snatch a one-shot win at the Ladies Open de France.
The Solheim Cup winner started the final day a stroke off the lead, but a five-under 65 powered the Spaniard to her third professional title.
Munoz piled the pressure on the French hopefuls with a blistering start, picking up birdies at the second, fourth, sixth, seventh and ninth holes to turn in 30.
She then added another birdie on the 15th before making her only mistake of the day at 17, but Munoz held her nerve to get up and down from the back of the final green to post the winning score of 14 under par.
"It's been a long year and I've been playing really bad and since Solheim it's got much better and I'm just really happy to have won here," said the 25-year-old.
"Right from the beginning I started to play really well; I hit it really close so I had a couple of tap-in birdies and in the end, I didn't make many putts, but it was enough from the front nine so I'm really happy."
Nocera and Derrey, who were joint overnight leaders along with compatriot Joanna Klatten, finished just adrift after both carded three-under 67s.
Nocera made a costly bogey on the par-three 16th while local professional Derrey failed to build on an outward nine of five under, coming home in two over after dropping shots at 13 and 14.
Klatten (68) was fourth on 12 under while Munoz's Solheim Cup team-mate Charley Hull was the leading English challenger on seven under.
