OTTAWA - Craig Anderson made 42 saves and Erik Karlsson and Erik Condra scored goals just under two minutes apart in the second period Tuesday as the Ottawa Senators defeated the Buffalo Sabres 2-0.
Anderson, who picked up his second shutout of the season, was especially sharp in the third period with the Sabres pressing for the tie as the Senators (7-4-2) snapped a mini two-game slide.
Ryan Miller made 29 saves in taking the loss for Buffalo (5-8-1).
Scoreless after the first period, the Senators had a number of great chances in the second but couldn't beat Miller until Karlsson moved in shorthanded and blasted a shot just over the Buffalo goalie's left pad at 15:20.
Condra then doubled the Ottawa just 1:54 later off, banging home a loose puck off a scramble in front Miller's goal.
Daniel Alfredsson had a great chance to open the scoring for the Senators on the power play prior to the two-goal barrage, but the Ottawa captain's one-timer missed the net with Miller at his mercy.
Buffalo had a chance to get back in the game midway though the third when Ottawa's Jim O'Brien went off for holding and Kyle Turris was whistled for high sticking to set up a two-man advantage for 14 seconds. But Anderson and the Senators penalty killers did the job against a Sabres power play that finished the night 0-for-4.
Ottawa's Jakob Silfverberg had a chance to stretch the Senators' lead to three on a power play later in the period, but Miller sprawled to make a diving save at the side of the Buffalo net.
The Sabres held a 13-7 shot advantage in the first period but couldn't solve Anderson.
Despite the win, Ottawa finished the night a disappointing 0-for-8 on the power play.
