Edmonton, AB -- (Sports Network) - Ales Hemsky picked up a goal and one assist while Patrick O'Sullivan notched the game-winner in the third as Edmonton used a three-goal final period to rally past Colorado, 6-4, at Rexall Place.

Sam Gagner and Gilbert Brule also contributed a goal and a helper for the Oilers, who snapped a four-game losing skid. Shawn Horcoff and Ryan Potulny also tallied for Edmonton, which tied a season-high for goals in one contest.

Jeff Deslauriers got the win despite stopping only 14-of-18 shots, but picked up his first NHL point with a late assist.

Milan Hejduk scored a pair of goals for the Avalanche, who have dropped four of five. David Jones and Kyle Cumiskey also tallied and Peter Budaj took the loss after allowing five scores on 32 shots.

"Any good team when you have a lead 4-3 going into the third period on the road on back to back nights you've got to find a way those games," said Avalanche head coach Joe Sacco. "Those are the games you got to put away, and we didn't do that tonight. We need to shoot the puck more, we need to generate more offense."

Potulny's redirection of Tom Gilbert's dish in the slot at 2:45 of the third period tied the game, 4-4, on an Edmonton man advantage, and O'Sullivan tallied inside of nine minutes to play to give the Oilers a one-goal cushion before Hemsky hit the empty net for the clincher with 43 seconds remaining.

Colorado got the game's first goal at 8:26 of the first period, when Hejduk followed up Tom Preissing's shot for a rebound score.

Horcoff swept up Hemsky's rebound at 16:39 for a 1-1 tie but Hejduk struck again from the right circle for a 2-1 Avs edge at 18:36.

Brule knotted the game just 21 seconds into the second period, but Jones re- established a Colorado advantage at 1:14.

Cumiskey boosted the visitors to a 4-2 lead at 11:04, but the Avs couldn't capitalize on a 5-on-3 advantage several minutes later.

Edmonton made it a one-goal contest with 16 seconds left in the period thanks to Gagner stashing home Lubomir Visnovsky's rebound.

"Any time you can get a goal in the last minute it gives your team a boost, and we came out charging the next period," Gagner said. "We were just trying to continue to put some pressure on them and we were able to come back and get the win."
