OTTAWA - Sergei Gonchar scored on the power play with 2:30 left in regulation Tuesday as the Ottawa Senators battled back from a sluggish start to defeat the Washington Capitals 3-2.
Jim O'Brien and Milan Michalek also scored for the Senators (4-1-1), who got 31 saves from Craig Anderson.
Troy Brouwer and Matt Hendricks scored for the Capitals (1-4-1). Michal Neuvirth stopped 24 shots in taking the loss for Washington, which blew a 2-0 lead.
The Senators should consider themselves lucky to walk away with the two points after showing little emotion through most of the first two periods.
Gonchar's winner came after Erik Karlsson wove through the Capitals' defence on a man advantage before finding his defence partner, who fired a one-timer that deflected off Hendricks in front and past Neuvirth with Ottawa's Chris Neil screening on the play.
Then with time winding down and Washington pressing for the tie, Anderson made a great save on Alex Ovechkin before robbing Mike Ribeiro from in tight.
Trailing 2-0 late in the second period and looking for a spark, Senators coach Paul MacLean chose to double-shift the one line that showed any jump.
The gamble paid off as O'Brien, who celebrated his 24th birthday, cut the lead in half with 1:23 remaining in the period on a setup from Erik Conda and AHL callup Mika Zibanejad.
The Senators then quickly tied the game at 2:20 of the third. Kyle Turris won a faceoff in the offensive zone and pushed the puck ahead to Michalek, who scooped it passed a surprised Neuvirth.
Playing without Jason Spezza because of an undisclosed upper body injury, the Senators struggled and the Capitals owned much of the momentum in the first period and jumped out to a 2-0 lead.
A turnover by Guillaume Latendresse midway through the period at the Senators' blue-line allowed Wojtek Wolski to jump on the puck and feed Brouwer, who caught Anderson moving the wrong way.
Washington then made it 2-0 as Hendricks tipped Jay Beagle's shot home.
The Senators continued to struggle in the second and seemed incapable of breaking through the Capitals' forecheck as Washington pinned the home side in its own end for nearly two minutes, leading to a chorus of boos from the 19,267 on hand at Scotiabank Place.
The Senators are back in action Wednesday when they host the Montreal Canadiens, while the Capitals head to Toronto to take on the Maple Leafs on Thursday.
