ST. LOUIS

Jaden Schwartz and Alex Pietrangelo scored second-period power-play goals and Jake Allen made 23 saves to help the St. Louis Blues beat the Calgary Flames 5- 2 on Wednesday night.

St. Louis has won three of its last four, losing only to red- hot Las Vegas in overtime.

Calgary had won its first four road games this season. Mikael Backlund scored twice for the Flames.

Schwartz and Pietrangelo scored in a span of 2:46 to break a 1- 1 tie. The Blues had come up empty on their previous 18 power-play chances.

Alexander Steen added a goal and three assists for the Blues. It was his first points of the season after missing the first six games with a broken thumb.

Paul Stastny scored with 3:32 left to push the lead to 4-2. Joel Edmundson added an empty- net goal with 43.9 seconds left.

Blue Jackets 5, Sabres 1

COLUMBUS, Ohio (AP) — Seth Jones had a goal and an assist for Columbus to help the Blue Jackets beat the Sabres.

Serge Bobrovsky stopped 34 of 35 shots to lead Columbus ( 6- 3- 0) to its fifth win in its last seven games.

Buffalo dropped to 3-6-2 in front of goalie Chad Johnson, who stopped 33 of 38 shots.

The Jackets power play had been an anemic 2-for- 20, but got a goal at 12:00 of the first period after Zach Redmond’s hooking call. Oliver Bjorkstrand whipped his second goal of the season past Johnson off an around-the-horn pass from Jones to Sonny Milano, and a picture perfect screen by Boone Jenner.
