Oilers 4, Senators 1 .

OTTAWA - Andrew Cogliano and Gilbert Brule each had a goal and an assist in the third period to lead the Edmonton Oilers to a 4-1 win over the Ottawa Senators on Monday night.

Martin Gerber made 22 saves to win for the second time in two starts for Edmonton. Tom Gilbert scored a power-play goal late in the second to draw the Oilers even at 1-1.

Cogliano deflected Brule's slap shot from the left point past Brian Elliott to give Edmonton a 2-1 lead 4:19 into the third. Brule tapped home Cogliano's centring pass at 12:48 to put the Oilers up 3-1. Dustin Penner assisted on both goals.

Taylor Hall scored into an empty net with 1:55 remaining.

Nick Foligno scored his of the season in the opening period for the Senators, who have lost six of eight.

Elliott stopped 21 shots after recording his second shutout of the season in Saturday night's 3-0 win over Toronto.

The Oilers, who lost 4-3 to San Jose on Saturday, play in Montreal on Wednesday night. They wrap up their three-game trip to Eastern Canada on Thursday in Toronto.

Gilbert tied it at 1-1 with 1:21 left in the second while Ottawa's Chris Neil was serving a tripping penalty. The Edmonton defenceman took Sam Gagner's pass back to the left point and drove a long-range slap shot past Elliott for his fourth goal.

Ottawa took advantage of a couple of breaks to take a 1-0 lead 6:30 in.

Neil's dump-in along the right boards took an odd bounce off the glass and the puck went to Foligno in the slot. Gerber stuck out his left pad to stop Foligno's backhander, but the rebound was redirected into the net off Oilers defenceman Ladislav Smid's skate.

NOTES: Gerber backed up Ray Emery when Ottawa went to the Stanley Cup final in 2007 ... Senators defensemen Brian Lee and David Hale were left out of the lineup ... Ottawa is at home again Thursday night, when Dany Heatley and the San Jose Sharks visit Scotiabank Place (7:30 p.m., TSN, Team 1200).
