Senators 1, Bruins 0
SENATORS 1, BRUINS 0: Robin Lehner turned aside 32 shots for his first career shutout and visiting Ottawa ended a long hex 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 move to 7-1-1 in its last nine and close within a point of the Bruins atop the Northeast Division.
Karlsson, who was 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.
