The Florida Panthers continued their remarkable run of form with an 11th-straight win on Thursday, as they overcame the Ottawa Senators 3-2.
Aleksander Barkov scored an important third-period goal, putting the Panthers 3-1 up and out of sight of the Senators, with Milan Michalek's sixth goal of the NHL season proving merely a consolation.
Reilly Smith and Vincent Trocheck both scored their 12th goals of the campaign, before Barkov's third-period goal - which also proved his 12th of the season.
The Philadelphia Flyers won just their second game in five with a tight 4-3 victory over the Minnesota Wild.
The Flyers were looking good midway through the second period when quick goals from Michael Del Zotto and Ryan White put the visitors 3-1 up, but a late equaliser from Minnesota's Zach Parise made it 3-3.
Del Zotto scored his second of the game in overtime to seal the win for the Flyers.
The Washington Capitals stayed clear of the Panthers atop the Eastern Conference with a dominant 4-1 effort against the New York Islanders, while the Dallas Stars overcame the Winnipeg Jets with a 2-1 shoot-out win.
The Toronto Maple Leafs saw their three-match winning streak ended with a 2-1 loss against the Los Angeles Kings, while the Detroit Red Wings defeated the San Jose Sharks 2-1 courtesy of a Justin Abdelkader goal in the third period.
