First-place Calgary had a chance to give itself more breathing room in the Pacific Division race. Fortunately for the Sharks, the Flames failed to do so.
Calgary, six points ahead of the second-place Sharks, was beaten at home for the second consecutive game, falling to the Stars 2-1 on Wednesday night.
The NHL’s highest-scoring team at home, Calgary has just one goal in the first two games of a three-game homestand.
The Flames scored 29 times at the Saddledome during their five-game winning streak that preceded this stretch.
Alexander Radulov and Miro Heiskanen scored for Dallas, which lost goalie Ben Bishop to a lower-body injury in the second period. Anton Khudobin made 15 saves in relief of Bishop and was credited with the win.
Avalanche 4, Golden Knights 3: Philipp Grubauer stopped 34 shots as host Colorado won for the fifth time in six games to stay two points in front of Arizona for the last wild-card spot in the Western Conference.
With its loss, Vegas — third in the Pacific Division — remained five points behind the Sharks.
Trailing 3-0 midway through the second, the Golden Knights got goals from Paul Stastny and Reilly Smith to climb back into the game. Gabriel Bourque extended the lead to 4-2 with his second goal of the season with 2:50 remaining in the period.
Bruins 6, Rangers 3: David Pastrnak had three goals and two assists as Boston, second in the Atlantic Division, extended its lead over third-place Toronto to six points by running its home winning streak to 12 games.
Pastrnak became the first Bruins player with three hat tricks in a season since Cam Neely in 1993-94.
Flyers 5, Maple Leafs 4: Sean Couturier scored in the only goal of the shootout in the fifth round as visiting Philadelphia moved to eight points behind Montreal for the Eastern Conference’s final playoff spot with five games remaining.
Former Sharks center Patrick Marleau of Toronto tied Mark Recchi for fifth place all-time in games played with his 1,652nd appearance.
