Mark Giordano scored 52 seconds into overtime to lift the Calgary Flames over the Chicago Blackhawks 4-3 on Sunday night.

 

Matthew Tkachuk had two goals and Sean Monahan also scored for Calgary, which had lost five of seven home games. Mike Smith turned away 34 shots.

 

Leading 1-0 after the first period thanks to a buzzer beater by Tkachuk, Calgary increased its lead to two when Tkachuk scored his second power-play goal of the night at 4:42, steering in Johnny Gaudreau's centering pass.

 

The Flames took a 3-0 lead 1:05 seconds later with Gaudreau again orchestrating the setup, this time to Monahan in front, who snapped his nine-game goalless drought.

 

Chicago answered right back with two quick goals.

 

Oesterle has goals in two straight games. He went the first 36 games his career without a goal until scoring in the 4-3 win over Edmonton on Friday.

 

Fifty-six seconds later, Oesterle was in the middle of things again, his point shot was kicked out by Smith but Toews buried the rebound.

 

With Corey Crawford (upper body) sidelined, Glass, a Calgary native, made his second-straight and second career start for Chicago and was solid again.
