Blackhawks rout Blues
Chicago Blackhawks kept themselves in touch with top spot in the NHL Western Conference by beating the St Louis Blues 4-0.
The Hawks scored late in each of the first two periods, through Duncan Keith and Andrew Shaw, before Marcus Kruger and Ben Smith wrapped up the win in the third.
St Louis remain four points clear of the Anaheim Ducks and San Jose Sharks at the top of the conference, with Chicago two points further back and holding the fourth seed.
The win took Chicago a point ahead of the Colorado Avalanche, who lost 5-4 in overtime to the Winnipeg Jets.
Having initially come from behind after Ryan O'Reilly's opener, Winnipeg led three times - Andrew Ladd scoring twice - before Colorado's Cody McLeod forced an extra period.
But Blake Wheeler added a winning goal to his two assists as the hosts finally prevailed.
Eddie Lack had a 30-save shut-out and Nicklas Jensen and Alexander Edler scored in quick succession in the third period to give the Vancouver Canucks a 2-0 win over the Nashville Predators.
The Tampa Bay Lightning moved alongside the Montreal Canadiens in second in the Atlantic Division and third in the Eastern Conference play-off standings with a 5-3 win over the Toronto Maple Leafs.
Captain Steven Stamkos scored a hat-trick - with his only three shots - and Radko Gudas and Tyler Johnson also found the net.
