Caen, France – Marseille picked up its second-straight Ligue 1, at the Stade Michel d'Ornano.
Marseille took the lead after 20 minutes with a goal from Andre Ayew, but Caen was able to quickly cancel the strike as Frau converted a penalty kick two minutes later to equalize.
Jordan Ayew put Marseille in front for good just seven minutes into the second half, claiming his second goal of the Ligue 1 season.
Marseille has now won five of its last six Ligue 1 contests, helping the club move into seventh place with 26 points.
Caen entered Friday's match trailing Marseille by just two points, missing an opportunity to jump ahead of its Friday opponents by dropping its second- straight result.
The win helps Marseille put some additional pressure on surrounding teams in the table ahead of full slate of fixtures over the weekend.
St Etienne and Lorient both trail Marseille by a single point and can take back their positions in the table with road wins on Saturday. St Etienne travels to Brest while Lorient heads to league-leading Montpellier.
Elsewhere on Saturday, third-place Lille looks to preserve its 13-game Ligue 1 unbeaten streak when it faces Ajaccio, while Dijon hosts Sochaux, Evian hosts Valenciennes, and Nice hosts Rennes.
On Sunday, second-place PSG hosts Auxerre looking to overturn a two-game losing skid. Bordeaux will also host Nancy on Sunday while Lyon and Toulouse conclude the weekend action at the Stade de Gerland.
