It was the Senators’ first victory in five games against the Bruins this season.
The Senators moved one point behind the Northeast Division-leading Bruins, who have played four fewer games. Ottawa won for the sixth time in seven games and sent the Bruins to their fourth loss in six.
The 20-year old Lehner was playing in just his 11th NHL game. He started because regular goalie Craig Anderson is sidelined indefinitely after cutting his hand last week in a kitchen accident.
In San Jose, California, Ryane Clowe scored the lone goal early in the first period and Antti Niemi made it stand up with 26 saves for his fifth shutout as San Jose returned home from a grueling road trip and beat Philadelphia.
The Sharks had gone 2-6-1 on the 17-day trip that knocked them out of first place in the Pacific Division and into a precarious position for a playoff berth.
With little room for error in the final quarter of the season, the Sharks managed to hold on thanks to a strong bounceback performance by Niemi to beat the Flyers for the ninth straight time.
Niemi lost four of five games on the trip and didn’t even make it out of the first period in two of those games. The Sharks allowed 35 goals during the road trip but gave up none to the NHL’s highest-scoring team, surviving a wild scramble in front of the net in the final minute.
In Glendale, Arizona, Mike Smith stopped 39 shots, Ray Whitney scored in the third period and during the shootout, and Phoenix extended its point streak to 12 games by beating NHL-leading Vancouver.
Smith allowed a goal on a carom in the first period, but nothing else. He stopped Alexander Edler and Mason Raymond in the shootout to extend his career-best and franchise-record winning streak to 11 games. Whitney scored in the third period to tie it and Mikkel Boedker sealed Phoenix’s sixth straight win with a nifty move to beat Cory Schneider in the shootout. The Pacific Division-leading Coyotes have won seven straight home games.
In Columbus, Ohio, Henrik Zetterberg scored the go-ahead goal and added an assist, and Joey MacDonald had 28 saves to help Detroit end a three-game slide by beating Columbus.
Johan Franzen had a goal and two assists, Niklas Kronwall and Valtteri Filppula both added a goal and assist, and Jan Mursak also scored for the Red Wings, who are 26-3-2 at home but only 16-16-1 on the road.
MacDonald, 7-1-1 this season playing behind No. 1 goalie Jimmy Howard, made a big stop on Ryan Russell’s short-handed breakaway to keep the game tied at 2 in the third period.
In Washington, Alex Ovechkin scored at 1:35 of overtime after Troy Brouwer tallied twice in the final 3 1/2 minutes of regulation, giving Washington an improbable win over the New York Islanders.
Blanked by Evgeni Nabokov for 56 minutes, the Capitals mounted a stunning rally to win their third straight — their longest streak since an identical run in mid-January.
Brouwer cut the deficit to 2-1 with 3:29 left in regulation, and then, after Capitals coach Dale Hunter pulled goalie Michal Neuvirth, Brouwer deflected a shot by Brooks Laich past Nabokov to tie it with 25.5 seconds to play.
It was the fourth straight road loss for the Islanders, who were 13-1-5 when leading after two periods.
In Raleigh, North Carolina, Bryan Allen scored his first goal of the season on a breakaway coming out of the penalty box, and Carolina held on to beat Nashville.
Nashville’s Gabriel Bourque scored less than a minute later — at 2:16 of the third period — to cut Carolina’s lead to 4-3, but the Predators couldn’t tie it.
Eric Staal and Tim Brent scored power-plays goals in the second period, and Jamie McBain had Carolina’s first goal earlier in the frame.
In Tampa, Florida, Steven Stamkos scored his NHL-leading 44th goal, and Tampa Bay beat slumping Montreal.
Adam Hall also scored for the Lightning, who are 11th in the Eastern Conference and trail eighth-place Washington by five points. Mathieu Garon finished with 23 saves.
David Desharnais scored for the Canadiens, who have lost five in a row and been outscored 16-5 in that stretch.
Tampa Bay went ahead 2-1 when Hall ended his 45-game goal drought, dating to the season opener against Carolina.
In Toronto, Mike Santorelli scored twice for Florida in a road win over Toronto.
Loud chants of “Fire Wilson!” directed at coach Ron Wilson were heard twice during the third period as the Leafs lost for the ninth time in 10 games, including all four on a homestand. Toronto is four points out of a playoff position in the Eastern Conference.
Marcel Goc, Jason Garrison and Stephen Weiss also scored for Florida, which leads the Southeast Division with 72 points. Jose Theodore added 28 saves.
Kings 4 Wild 0: In St. Paul, Minnesota, backup goalie Jonathan Bernier stopped 25 shots for his fifth NHL shutout, and Anze Kopitar scored and added in Los Angeles’ rout of Minnesota.
Justin Williams, Dwight King and Jordan Nolan added goals for Los Angeles, which entered the game having won only one of six. The Kings moved into a tie with Dallas and Colorado for the eighth place in the Western Conference.
