33-year-old Landeskog scored the first goal of the match, when he sent the puck through the crease behind the goal and off the skates of goalie and compatriot Anton Forsberg.
Artturi Lehkonen's 3–1 also went in off the skates. The Finn's shot deflected off Adrian Kempe - who earlier had an unsuccessful power-play attempt - and into the back of the net past Forsberg.
With the victory, Colorado has a solid grip on the series and leads 3–0. With another away win, the club will advance to the quarterfinals of the Stanley Cup playoffs.
