Matt Duchene pounced on a loose puck just in time to turn it into a game-winning goal. Duchene corralled a deflection from teammate P.A. Parenteau's desperation, long-distance shot and scored his second goal of the night as time was about to expire in overtime, lifting the Colorado Avalanche over the San Jose Sharks 3-2 on Sunday to stretch their home winning streak to a season-high five games.
