Colton Parayko scored the overtime winner on a rebound and the St. Louis Blues beat the Calgary Flames 4-3 on Thursday night.

Robert Thomas had a goal and two assists, Zack Bolduc and Pavel Buchnevich scored and Philip Broberg had two assists for the Blues. Jordan Binnington made 36 saves in the win.

Jakob Pelletier, Matt Coronato and MacKenzie Weegar scored for the Flames, whose six-game win streak at home ended.

The Flames twice tied the game after falling behind. Jonathan Huberdeau, from behind the net, shoveled the puck out to an unchecked Weegar, who shot the puck past Binnington at 7:06 of the third period to tie it at 3.

Pelletier’s first goal this season halved the deficit just 15 seconds after Thomas gave the visitors a 2-0 lead at 14:49 of the first period. Coronato’s power-play goal drew the Flames even at 2 5:23 into the second period.

Calgary’s goaltender Dan Vladar stopped 20 of 24 shots.

Blues: Improved to 4-0-1 since Jim Montgomery was named head coach Nov. 24. Thomas has eight points - three goals, five assists - in eight games since returning from a fractured ankle.
