Connor McDavid scored in the third round of the shootout to help the Edmonton Oilers salvage a 4-3 win over the Calgary Flames on Thursday night.

Brandon Davidson scored twice and Zack Kassian had a goal for the Oilers, who rallied from 2-0 down to win their fourth in five games.

Matthew Tkachuk had two goals and Mark Giordano also scored for the Flames, who have a point in 11 straight games despite their fourth straight loss in extra time (7-0-4).

Calgary scored 1:32 into the first period on the first shot of the game. After a giveaway by Oilers forward Milan Lucic, Troy Brouwer chipped a puck from behind the net out to Tkachuk, who scored his 15th of the season on goalie Cam Talbot.

It was the eighth time this season the Oilers have allowed a goal on an opponent's first shot.

Calgary made it 2-0 with 5:39 to play in the opening frame when Giordano scored on a long screen shot during a delayed penalty.

The Oilers finally got on the board with six minutes to play in the second as a spin-around shot from a bad angle by Davidson surprised goalie David Rittich.

Edmonton tied it just over a minute later when Kassian cashed in on the rebound from Leon Draisaitl's shot.

The Oilers took the lead five minutes into the third period when Ryan Strome fed it in front to Davidson, who scored his second of the game and the season.

Calgary pulled back even eight minutes into the third when Edmonton defenseman Matt Benning lost the puck behind his net, leading to Tkachuk's second goal of the game.

Strome had a goal called off in overtime on goaltender interference, much to the ire of Edmonton fans.

NOTES: It was the third of five meetings between the teams this season, with Edmonton winning the previous two and the last six encounters overall.
