Title-challengers Marseille squandered a chance to move provisionally top of Ligue 1 on Sunday as they slumped to a 3-0 defeat at home to Lorient.
Jeremie Aliadiere scored a first-half penalty after the hosts had Charles Kabore dismissed before strikes from Benjamin Corgnet and Kevin Monnet-Pacquet after the restart handed Lorient just their second win on their travels since the opening game of last season.
A third victory in four for Christian Gourcuff's side bumped Lorient up to eighth in the table, as Marseille stayed third, level on points with Paris Saint-Germain and two behind leaders Lyon, who are in action against Saint-Etienne later on Sunday.
The visitors were awarded a penalty seven minutes before half-time as Burkina Faso midfielder Kabore was sent off for a second yellow card after hauling down Aliadiere inside the area.
The former Arsenal striker then sent Steve Mandanda the wrong way from the spot for his sixth goal of the campaign.
Lorient's second arrived two minutes after the break as Corgnet steered Alain Traore's cross beyond Mandanda, the ball looping over the helpless France reserve keeper following a deflection off Jeremy Morel.
A string of fine saves from Lorient keeper Fabien Audard to deny Morgan Amalfitano, Nicolas N'Koulou and Souleymane Diawara kept the away side's two-goal lead intact before Monnet-Pacquet added a third on 70 minutes, drilling low into the corner from the top of the box to complete the misery for Elie Baup's men.
Earlier, Reims saw their winless run extended to eight matches following a goalless draw at home to sixth-placed Bordeaux.
