Mangiapane's winner headlines 3-goal final frame as Flames put Stars on brink

Mikael Backlund, Andrew Mangiapane and Trevor Lewis all scored in the third period, leading the Calgary Flames to a 3-1 victory over the visiting Dallas Stars on Wednesday night to take a 3-2 lead in their first-round playoff series.

Jacob Markstrom made 20 saves for the Flames, who can win the series Saturday in Dallas. If necessary, Game 7 would be back in Calgary on Sunday.

Jason Robertson scored the lone goal for Dallas, and Jake Oettinger stopped 29 shots.

But the line of Backlund, Mangiapane and Blake Coleman struck in the third.

Mangiapane circled out from behind the goal line and centred the puck for Backlund's redirect by Oettinger to make it 1-1 at 6:49 of the third.

The Flames took the lead when Backlund was in the neutral zone and fed a backhand pass to Mangiapane at the Stars' blue line. Mangiapane took three strides in and beat Oettinger's glove with a high shot at 13:20.

Lewis sealed it with an empty-netter with 58 seconds left.

Neither team scored on their two power-play chances and are 2-for-19 in the series.

Flames forward Johnny Gaudreau took a deflected puck in the side of the head at the Stars' blue line. He went to the dressing room for treatment late in the period, but was back in the game in the second period.
