Defenseman Erik Karlsson scored twice in the last 8:48 and the Ottawa Senators beat the Florida Panthers 2-1 on Thursday night.

Former Florida backup Craig Anderson stopped 33 shots and came within 4:13 of his second shutout since being acquired in a trade from Colorado on Feb. 18. Anderson, who has started every game since going to Ottawa, has allowed one goal or fewer in seven of his nine starts.

He outdueled his former goalie partner in Florida, Tomas Vokoun, who stopped 37 shots.

Defenseman Clay Wilson scored for Florida.

Karlsson opened the scoring at 11:12 of the third, taking a loose puck along the boards, skating in on Vokoun and firing a quick shot from a sharp angle. The puck trickled in after getting through between Vokoun's left arm and his body.

With Ottawa on the power play, Karlsson scored again with 5:10 left. He put home a rebound after Vokoun stopped Gonchar's slap shot from the point.

Wilson scored his second goal in the last two games to close the gap to 2-1. He swept the puck past Anderson after Niclas Bergfors' pass toward the net was deflected.

Early in the third period, Ottawa killed a 5-minute Florida power play after Francis Lessard was given a major and game misconduct for leaving his feet and checking Scott Timmins in the head area.

The Senators killed off four power plays in all, extending their streak to 31 consecutive penalty kills.

Ottawa has won all three meetings this season. The Senators won the first one 5-3 on Oct. 28 and took the second 5-1 on Feb. 23 in Anderson's second game with the team.
