France kept their dreams of a first Grand Slam and Six Nations title since 2010 alive with a tense 13-9 victory over Wales - in a game that featured Dragons duo Will Rowlands and Ross Moriarty.
An Anthony Jelonch try and eight points from Melvyn Jaminet set up the victory for the visitors.
Wales - who started with Rowlands and introduced Moriarty in the second period - responded with three Dan Biggar penalties, but could not break down the resolute French defence.
Fabien Galthie's side will aim to complete the Grand Slam against England next Saturday in Paris, while Wales host Italy in their final game.
