Marchand scores in OT to lift Bruins over Flames 2-1
David Pastrnak also scored for Boston (36-13-8), which moved within one point of Tampa Bay for first place in the Atlantic Division and Eastern Conference. The Bruins, who are 12-1-2 in their last 15 road games, have two games in hand on the Lightning.
Boston has lost only three times in regulation in the last 28 games (21-3-4). Tuukka Rask made 28 saves.
Matthew Tkachuk scored for the Flames (30-21-9), who fell to 1-3-4 in their last eight home games. They began the day one point out of third place in the Pacific Division.
Starting goalie John Gibson (22-15-6) stopped all 13 shots he saw for Anaheim, but was inadvertently clipped by Vegas' Reilly Smith behind the net with three seconds left in the second period and didn't return due to a lower-body injury.
Backup goalie Ryan Miller played cleanup in the third, stopping 20 shots to preserve the win.
The Ducks have won four of five away from home. Anaheim became just the seventh team - and fifth in regulation - to win on Vegas' home ice.
Vegas, which leads the NHL with 82 points, had its three-game winning streak snapped.
BUFFALO, N.Y. (AP) - Alex Ovechkin scored his league-leading 35th goal and Washington reclaimed the top spot in the Metropolitan Division with a win over Buffalo.
Evgeny Kuznetsov sealed the victory by scoring into an open net with 26 seconds remaining. Washington completed a 2-1-1 road trip and bounced back from a 7-1 loss at Chicago on Saturday.
Washington improved to 34-18-7 for 75 points, one ahead of idle Pittsburgh.
Dion Phaneuf added his second goal in three games since joining Los Angeles in a trade with Ottawa, and Jonathan Quick made 27 saves in the Kings' second straight win since a three-game slide. Los Angeles (32-22-5) also improved to 3-3 on its seven-game trip as it fights for playoff positioning in the Western Conference.
Last-place Chicago looked awful for most of the night during its ninth loss in 10 games, and Quick turned away a possible comeback early in the third. Anton Forsberg made 29 stops for the Blackhawks (25-27-8), and Patrick Sharp snapped an 11-game scoring drought with his seventh goal of the season.
It was the first game at the United Center since the Blackhawks banned four fans from their home games for directing a racist taunt toward Washington's Devante Smith-Pelly. The team also apologized to the forward and the Capitals.
The Predators recorded two power-play goals and scored on the man advantage in their second straight game after going six games without converting on the power play.
Pekka Rinne made 36 saves to earn his 30th win of the season.
The Predators improved to 12-3-3 in their last 18 games.
