"(Ward) was real solid," said Eric Staal. "He's really stepped back into his game and we're going to need him and he helped us get the win."
The Hurricanes tied it 1-1 on their third shot of the second when Drayson Bowman made a cross-ice pass to LaRose, who snapped a shot from the faceoff circle to beat Anderson glove side.
"This was one of those nights (when) you win the game, but lose on the scoreboard," Anderson said. "We outplayed them, but just didn't get the results we were looking for. We deserved a better fate."
The Senators finally solved Ward in the second when Alfredsson gave Ottawa a 2-1 edge at 16:04, roofing a shot from a near-impossible angle that fooled the Carolina goalie.
"I was looking for (Senators forward Mika Zibanejad), but saw he was covered up so thought I'd try a shot," Alfredsson said. "I've tried it a lot of times and it usually doesn't work, but it came off perfect."
Mike Lundin made his debut for the Senators after missing the first 10 games with a broken finger, while fellow defenseman Sergei Gonchar returned to the lineup after missing the last two games with the flu.
