Sceviour helps Stars past Blues
Colton Sceviour scored the first two goals as the Dallas Stars beat Western Conference leaders the St Louis Blues 4-2.
The Stars, who hammered the Nashville Predators on Friday night, went two up although their lead was reduced to a goal by a brace of Alexander Steen powerplay goals in between Cody Eakin's strike for Dallas.
There would be no way back for the Blues, though, as they suffered their first regulation defeat at home in 10 matches and just their sixth for the season, as Antoine Roussel gave the Stars victory.
Jarome Iginla scored twice as the Boston Bruins beat the Washington Capitals by the same scoreline to clinch the Atlantic Division title.
The Bruins were three goals to the good midway through the second period after Iginla's double in-between Carl Soderberg's powerplay goal, while Patrice Bergeron added a fourth, with Jason Chimera and Evgeny Kuznetsov on target for Washington.
The Colorado Avalanche clinched their first Stanley Cup play-off spot in four years with a 3-2 victory over the San Jose Sharks, who have already qualified.
John Mitchell scored the decisive goal and provided an assist, while Paul Stastny and Cody McLeod also netted for the Avalanche, with strikes from Joe Pavelski and Dan Boyle coming in vain for San Jose.
Montreal and Los Angeles extended their winning streaks, with the Canadiens overcoming the Florida Panthers 4-1 and the Kings beating the Winnipeg Jets 4-2.
Max Pacioretty netted twice after an opener from Thomas Vanek, who also provided an assist, while David Desharnais completed the victory in the final minute to give the Canadiens their fifth successive win, with Brad Boyes' score for Florida merely a consolation.
The Kings went ahead through Trevor Lewis before Anze Kopitar's double put them clear and although Matt Halischuk gave Winnipeg some hope, Tyler Toffoli restored the three-goal cushion, meaning Blake Wheeler's goal counted for little as Los Angeles earned their sixth consecutive win.
Darren Helm's hat-trick sent the Toronto Maple Leafs crashing to their eight defeat in a row as the Detroit Red Wings claimed a 4-2 victory.
Gustav Nyquist also got on the scoreboard for Detroit, while the Leafs equalled their worst run since 1985 despite Cody Franson and Joffrey Lupul finding the net.
Zach Parise scored twice in the third period, in-between Jared Spurgeon's goal as the Minnesota Wild beat the Phoenix Coyotes 3-1, while Luca Sbisa, Matt Beleskey, Saku Koivu, Corey Perry and Mathieu Perreault all netted as the Anaheim Ducks thrashed the Vancouver Canucks 5-1.
Steven Stamkos scored twice, including the winner in overtime, as the Tampa Bay Lightning edged out the Buffalo Sabres 4-3, a powerplay goal in overtime from Ryan Johansen ensured the Columbus Blue Jackets squeaked past the Carolina Hurricanes 3-2, while Frans Nielsen scored in regulation time and added a penalty in the shootout as the New York Islanders dented the New Jersey Devils' play-off hopes with a 2-1 win.
