Markstrom made a glove save on Josh Anderson’s shot from the slot on a setup by Sean Monahan with 1:08 left in the third to hold onto Calgary’s 2-1 lead.
“It got close there at the end, but everybody did a great job blocking shots and clearing, and the penalty kill was really good once again,” Markstrom said.
Anderson has yet to score through his first 16 games. He has 122 goals in 473 NHL games, including 57 goals in 190 games the past three seasons for Montreal.
“It’s frustrating right now, especially when you have opportunities to help your team out, to tie the game or finish it,” Anderson said. “I’ve just got to dig deeper, bear down.”
Kadri gave the Flames a 1-0 lead at 2:35 of the second period. He spun around in the high slot after carrying the puck into the offensive zone and scored on a long wrist shot past Montembeault, stick side.
Lindstrom tied it 1-1 at 2:52 when he pinched to shoot a rebound over Markstrom for his first goal since Feb. 13 for the Detroit Red Wings in a 6-1 win against the Vancouver Canucks.
