ANAHEIM — A slog turned into a sprint as the home stretch of Wednesday’s game at Honda Center let the offensive fireworks fly, with the Ducks rallying from two goals down to defeat Calgary 4-3 in overtime, and potentially extinguish the Flames’ playoff hopes.

The Ducks have won two straight and are now back at .500 with four games remaining on their schedule. The Flames remained six points back of the final wild-card spot.

Cutter Gauthier scored two goals for the second straight game, including the tally that forced overtime and the OT winner, both of which were set up by Leo Carlsson.

Trevor Zegras and Frank Vatrano also lit the lamp, and goalie Ville Husso made his second start since arriving via trade from Detroit, making 36 saves.

Mikael Backlund, Yegor Sharangovich and Matt Coronato each had a goal for Calgary. Backlund added an assist and Joel Hanley chipped in a pair. Rookie Dustin Wolf stopped 19 shots.

In the third period, a game that had just one goal through almost 52 minutes saw five scored in the span of 4:23.

Calgary earned its second edge of the night with 6:16 left. It was the sort of simple, direct play that the Ducks have tried to emulate at times, with multiple shot attempts and recoveries. The last one, a low-flying bid off Husso’s pad by Joel Farabee, created a backhanded putback goal for Sharangovich.

Coronato appeared to have sealed the Ducks’ fate when he swiped in Backlund’s rebound to make it 3-1 with 4:48 to play. But the Ducks had other plans.

Carlsson set up Vatrano alone in the right circle for a no-doubt one-timer at 16:03. Eight seconds later a center-ice faceoff win set the wheels in motion for Carlsson to set up Gauthier on the left side to even the score at 3-3.

In overtime, Gauthier, who had been aggressive and dangerous throughout the evening, trailed a rush between Carlsson and Olen Zellweger, receiving the puck and picking his spot far side to complete the Ducks’ ninth third-period comeback of the campaign.

The Ducks finally solved Wolf with 8:11 left in regulation.

Mason McTavish’s forecheck pressure created a puck recovery from Oliver Kylington. His saucy seam pass found Zegras near the right faceoff dot, where he sold a pass before promptly placing a precise wrist shot above Wolf’s shoulder on the near side.

Husso was solid again, making saves on sterling opportunities for Rasmus Andersson and Nazem Kadri in the second.

But at the 14:18 mark, Calgary broke a scoreless tie off an effort that started and ended with Backlund. He stole the puck back in the Ducks’ zone following a pinch by Joel Hanley, initiating a sequence that culminated in Backlund redirecting MacKenzie Weegar’s shot past Husso.
