Senators fight back to blank Bruins
Robin Lehner turned aside 32 shots for his first career shutout and visiting Ottawa ended a long losing streak against Boston.
Red-hot defenseman Erik Karlsson scored the only goal Lehner would need as the Senators ended a streak of eight consecutive losses to the Bruins and won for the first time in five meetings this season.
Lehner improved to 3-0-0 this season by making 17 saves in the third period to help Ottawa avenge a 5-3 loss to Boston on Saturday and close within a point of the Bruins atop the Northeast Division.
Karlsson, named the league's first star of the week Monday, continued his blistering pace by hammering a slap shot past a screened Tim Thomas on the power play at 14:44 of the opening period.
It was the seventh goal in an eight-game points streak for Karlsson, who also has 11 assists during that span. Jason Spezza assisted to give him 21 points during a 10-game streak.
Despite turning aside 37 shots, Thomas had his six-game winning streak against Ottawa snapped. He had won 14 of his previous 15 decisions against the Senators.
Ottawa's last win in the series was a 2-0 victory in Boston on Nov. 13, 2010.
Lehner, who was called up from Binghamton last week following an injury to starting goaltender Craig Anderson, lost to the Bruins 4-2 on Feb. 18, 2011, in his final start last season.
Newly acquired Bruins Brian Rolston and Mike Mottau played for Boston.
