Walker Duehr's first career NHL goal for Calgary on Thursday night broke a scoreless tie in the second period, and the 23-year-old winger who was born in Sioux Falls became the first South Dakota-born player to score in the NHL.

Dillon Dube scored twice in the third period and Dan Vladar made 25 saves, helping the Flames to a 4-1 win over the St. Louis Blues.

Dube broke a 1-all tie, scoring with 9:10 left in regulation and added an empty-netter in the final minutes. Blake Coleman pushed the lead to 3-1 with his eighth goal of the season with 3:56 left.

Calgary has recorded points in 16 of its last 19 games.

Duehr took a pass from Nazem Kadri late in the second period and wristed a shot past goalie Thomas Greiss, who had stopped 61 successive shots over his last three games. Nazem Kadri set up the goal with a pinpoint pass on a 2-on-1 breakout.

Duehr was called up over the weekend and made the second start of his career on Tuesday. He played in one game for the Flames in 2021.

Duehr's goal seemed to ignite his teammates. Calgary scored three third-period goals in a span of 5:49.

Vladar, who wears No. 80, improved to 7-4-4 this season.

Jake Neighbours scored for St. Louis, which had won eight of its last nine against the Flames, including a 4-3 overtime decision on Tuesday.

Dube picked up a loose puck in the slot and broke a 1-all tie with his eighth goal of the season. He scored into an empty net with 3:21 left.

The Blues are without Vladimir Tarasenko (hand) and Ryan O'Reilly (foot) for four to six weeks.

Greiss made 36 saves and kept his team in the game over the first three periods.

The Blues face Tampa Bay on Saturday in the third of seven successive home games.
