CALGARY, Alberta (AP) Johnny Gaudreau had his first two-goal game of the season and the Calgary Flames scored three goals in the first three minutes of the third period, rallying to beat the Toronto Maple Leafs 4-2 on Thursday night.
Gaudreau tied it 2-2 just 19 seconds into the third, sending a wrist shot past Frederik Andersen after being set up by Mikael Backlund.
Then, after Michael Frolik's third goal in as many games at 1:59 gave the Flames the lead, Gaudreau scored again, his ninth of the season. He deflected Travis Hamonic's point shot through Anderson's legs. The three goals came on three consecutive shots.
Hamonic also had a goal Calgary (18-12-4). Sean Monahan had a pair of assists to extend his point-streak to eight games (5 goals, 5 assists).
The Flames improved to 7-0-0 under interim head coach Geoff Ward and moved into a tie with the Edmonton Oilers for second in the Pacific Division.
Mitch Marner and John Tavares each had a goal and an assist for Toronto (15-14-4). The Leafs fell to 2-1-0 on their four-game trip.
Shortly after the Flames surged in front, Toronto got a 1:34 two-man advantage, but failed to take advantage as David Rittich made big stops off Tavares. Auston Matthews also put a shot off the post.
Rittich finished with 32 saves and improved to 15-7-4.
Andersen made 20 saves and fell to 15-8-3.
Tied 1-1, Marner's fifth goal of the season at 14:06 of the second gave the Leafs the lead. The right winger completed a give-and-go with Tavares, sending a shot into the top corner.
After falling behind early, Calgary tied it 1-1 at 16:23 of the first. Hamonic moved in from the point, took a cross-ice pass from Monahan and beat Andersen with a high shot.
Toronto struck first at 8:24 of the first period when Tavares scored into the top corner, over Rittich's blocker, after being set up in front by Marner.
