Blackhawks 2, Flames 0
Nick Leddy and Brent Seabrook scored goals, and the Chicago Blackhawks snapped a season-worst, two-game losing streak, defeating the visiting Calgary Flames 2-0.

Oilers 3, Blues 0
The Oilers scored three times on their first seven shots and got a stellar performance from goalie Nikolai Khabibulin in beating the Blues 3-0, snapping St. Louis' home winning streak at four games and giving Edmonton its first win in four games.
Jordan Eberle scored twice and Taylor Hall knocked in a rebound of a shot by Eberle to give the Oilers only their second win in their last 14 games against the Blues and first since Dec. 11, 2009. Hall also earned assists on both of Eberle's goals.
Khabibulin stopped all 43 St. Louis shots, including a point-blank save on a shot early in the second period by David Perron, which could have tied the game at 1. That save was followed only seconds later by Eberle's second goal of the game, 3:26 into the second period.

Jets 4, Hurricanes 1
Evander Kane was involved in four scoring plays as the Winnipeg Jets created more distance in the Southeast Division standings by using two second-period goals to break a tie and defeat the Carolina Hurricanes 4-1.
Olli Jokinen, Tobias Enstrom, Nik Antropov and Kane scored for division-leading Winnipeg, which built its edge on second-place Carolina to six points in the standings.
Carolina, which has a season-long six-game losing streak, scored first on Jiri Tlusty's first-period goal. But from there, the Hurricanes, who hadn't played since Thursday night, ran short on execution.
Winnipeg goalie Ondrej Pavelec made 38 saves. Kane picked up three assists for the Jets.
