Ryan Miller stopped 31 shots and T.J. Oshie and Kevin Shattenkirk scored in a shootout as the Western Conference-leading St Louis Blues beat the Philadelphia Flyers 1-0 on Tuesday.
St Louis have 109 points, one fewer than East leader Boston for the top spot in the NHL.
Miller, who earned his 29th career shutout, made a skate save against Vincent Lecavalier and a glove save on Claude Giroux in the shootout.
San Jose’s Patrick Marleau scored his 32nd goal of the season with 7 minutes, 29 seconds left in the third period to lift the Sharks over Edmonton 5-4.
The Sharks had blown a 3-1 lead and were naught for five on power plays, before Marleau rocketed a shot past Ben Scrivens after the goalie had deflected a one-timer by San Jose’s Brent Burns.
Dan Boyle, Andrew Desjardins and Tommy Wingels also scored for the Sharks, who moved within one point of first-place Anaheim in the Pacific Division. Ryan Nugent-Hopkins had two goals and two assists for Edmonton.
In Buffalo, New York, Tyler Ennis scored twice in the third period and again in the shootout as the Sabres edged the New Jersey Devils 3-2.

The Devils are three points out of the Eastern Conference’s final wild card spot.

With 102 points, Colorado moved three ahead of Chicago for second place in the Central Division.
Tyler Johnson scored the go-ahead goal for Tampa Bay on a short-handed breakaway late in the third period as the Lightning clinched a playoff berth with a 3-1 victory over the Montreal Canadiens.
