CALGARY - Johnny Gaudreau finished off his hat-trick at 3:20 of overtime Friday night to give the Calgary Flames a dramatic 5-4 victory over the Boston Bruins.
Gaudreau took a pass from ex-Bruin Dougie Hamilton in the high slot, stickhandled in and beat Tuukka Rask with a low shot that resulted in hats immediately raining down on the ice.
Jiri Hudler forced the extra period for Calgary when he scored with 1.2 seconds remaining in regulation to tie the game 4-4.
Mark Giordano also scored for Calgary (10-14-2), which extended its win streak on home ice to six games.
Brad Marchand, with a pair, Matt Belesky with his first goal in 14 games and Zdeno Chara scored for Boston (13-8-3). The Bruins have points in their last seven games (5-0-2).
With two out of a possible four points so far, the Bruins wrap up their three-game Western Canadian road trip in Vancouver on Saturday night.
It was quite a night for Gaudreau, who has a strong Boston connection having played three years of college hockey at Boston College, winning the Hobey Baker Award in his final year. With an assist as well, it was his first career NHL four-point game.
In his second NHL season, Gaudreau leads the Flames in scoring and is on a nine-game point streak at home with 17 points (7 goals, 10 assists) during that span.
It was a frantic final 66 seconds of the third period.
First, Marchand broke a 3-3 tie on a penalty shot with 1:06 left. He got the opportunity when his stick was slashed out of his hand by Hamilton while he raced away on a short-handed breakaway.
However, off the ensuing face-off, Calgary pulled its goalie and went back to the attack and Hudler knocked in a loose puck to force overtime.
The Flames opened the second period ahead 2-1 but the lead disappeared at 1:36 when Marchand snapped a shot past Karri Ramo on the glove side.
Calgary regained the lead 20 seconds later when Gaudreau deked around Jonas Gustavsson and tucked in his second of the game. Coming on Calgary's 11th shot, it ended the night for the Bruins goaltender, who was pulled by coach Claude Julien and replaced with Rask.
The scoring barrage would continue. Making it three goals in the span of 46 seconds, the Bruins tied it up again 3-3 when Chara wristed a shot inside the far goal post.
Calgary opened the scoring 33 seconds into the game when David Jones neatly set up Gaudreau's first of the night.
The Flames extended their lead to 2-0 at 15:55 on Giordano's goal but the Bruins replied 1:24 later when Chara's shot caromed in off the leg of Beleskey.
Rask made 23 saves in relief to fall to 8-7-3.
Starting for the 14th time in the last 15 games, Ramo had 34 stops to improve to 8-8-1.
