Brian Elliott made 31 saves for his first shutout of the season and Daniel Alfredsson scored as the visiting Ottawa Senators skated to a 2-0 victory over the Boston Bruins on Saturday.
Erik Karlsson added his fourth goal of the season and defenseman Filip Kuba recorded an assist in his first game of the season as the Senators won for the fifth time in six games.
Elliott outdueled Bruins goaltender Tim Thomas, who shut out Ottawa earlier in the season and entered the game with an NHL-best .959 save percentage.
The Senators grabbed the lead at the 9:34 mark in the first when Karlsson took a pass from Chris Kelly and blasted a shot from above the right faceoff circle that beat Thomas between the pads.
Alfredsson got a fortunate bounce on his seventh goal of the season in the third period.
Kuba, who had missed the first 16 games of the season after breaking his leg in training camp, sent a pass around the left boards that caromed to Milan Michalek, who shuffled it to Alfredsson for the goal.
