DETROIT — Johnny Gaudreau and Sean Monahan scored in the first period, and the Calgary Flames started their road trip with a win, beating the Detroit Red Wings 4-2 on Sunday night.

Andrew Mangiapane scored Calgary’s last two goals, one of which came into an empty net at the end. Dylan Larkin had both goals for Detroit.

Gaudreau was alone in the left circle when he beat goalie Jonathan Bernier with a slap shot to make it 1-0. Monahan scored on a rebound 77 seconds later.

Larkin, however, got behind Calgary defenseman Michael Stone and beat goalie David Rittich to make it 2-1 later in the first period.

The Red Wings stayed within a goal until the final minute of the second. That’s when a slapper by Noah Hanifin appeared to carom in off the leg of Mangiapane with 10.6 seconds remaining.

“I thought we dug in in the second,” Detroit coach Jeff Blashill said. “I didn’t think we were good enough in the first. I thought we had some guys playing and some guys were just in their jerseys.”

With Detroit’s goalie pulled, Larkin made it 3-2 with 2 minutes remaining in the third when his wrist shot from the blue line sailed through traffic and past Rittich. Mangiapane sealed the win for Calgary with 11.8 seconds to play.
