A quick-fire brace from striker Kevin Berigaud helped Evian TG to a 2-0 home win, condemning AS Nancy to their third straight defeat.
The 23-year-old struck on the half-hour mark to put his team into the lead before doubling his total just two minutes later.
Berigaud's last goal came in Evian's 1-1 draw at Ajaccio in the third game of the season.
The win lifts Pablo Correa's men into 11th in Ligue 1, with a tough away match against AS Saint-Etienne next up for Les Roses.
Nancy slip into the bottom three, with their next fixture pitting them against Remi Garde's Lyon at home.
