CALGARY — Justin Kirkland scored in the sixth round of the shootout to help the Calgary Flames rally to a 4-3 win against the Pittsburgh Penguins at Scotiabank Saddledome on Tuesday.

Kirkland dragged the puck into the slot and beat goaltender Alex Nedeljkovic‘s glove with a wrist shot. Dustin Wolf made a stick save on Evgeni Malkin to clinch the win.

Rasmus Andersson had a goal and an assist, and MacKenzie Weegar and Nazem Kadri scored for the Flames (5-0-1), whose six-game point streak to open the season is the second-longest in franchise history. Wolf made 35 saves.

Bryan Rust and Rickard Rakell scored, and Nedeljkovic made 22 saves for the Penguins (3-4-1), who have lost three in a row.

Andersson put Calgary up 1-0 at 11:48 of the first period. Kirkland fanned on his pass through the slot, but Andersson picked up the loose puck and shoveled it over Nedeljkovic’s glove.

Rust tied it 1-1 at 6:31 of the second period with a power-play goal, beating Wolf glove slide on a wrist shot from the slot after a centering pass from Sidney Crosby.

Rakell threw a puck toward the net from below the goal line that deflected off the inside of Wolf’s pad and into the net to put Pittsburgh up 2-1 at 2:32 of the third period.

Weegar tied it 2-2 at 7:46 with a slap shot from the point that beat Nedeljkovic up high.

Noel Acciari chipped a rebound over Wolf’s glove for his first goal of the season to give Pittsburgh a 3-2 lead at 13:40, and Kadri evened it 3-3 with 43 seconds left in the game and Wolf on the bench for the extra attacker.
