Sean Monahan scored 2:09 into overtime to lift the Calgary Flames over the Colorado Avalanche 5-4 on Monday night.
The Flames have struggled against the Avalanche of late, starting with the first round of the 2019 playoffs when eighth-seeded Colorado won in five games. The Avs won the first two meetings this season as well.
Mangiapane broke a 2-all tie when he scored his sixth goal 12 seconds into the third period. Frolik made it 4-2 at 1:39, but the Avalanche rallied. MacKinnon's 19th at 3:59 got Colorado within a goal, and Donskoi's 13th at 10:45 tied it again.

The Flames have struggled against the Avalanche of late, starting with the first round of the 2019 playoffs when eighth-seeded Colorado won in five games. The Avs won the first two meetings this season as well.
Monahan ended the frustration with a shot from close that beat Avalanche goalie Pavel Francouz, who finished with 28 saves.
Colorado had won six straight, including three on an Eastern Conference road swing that ended Saturday in Boston. Nathan MacKinnon, Valeri Nichushkin, Ryan Graves and Joonas Donskoi scored for the Avalanche.

Mangiapane broke a 2-all tie when he scored his sixth goal 12 seconds into the third period. Frolik made it 4-2 at 1:39, but the Avalanche rallied. MacKinnon's 19th at 3:59 got Colorado within a goal, and Donskoi's 13th at 10:45 tied it again.
The Avalanche took an early lead on Graves' fifth goal in the first period, and the Flames tied it on Ryan's tip at 9:33 of the second. Nichushkin's fifth goal in eight games, and fifth of the season, 31 seconds later gave Colorado the lead again, but Tkachuk scored seven seconds into a power play to tie it.
