SUNRISE, Fla. -- Erik Karlsson scored the tie-breaking goal in the second period, and Craig Anderson continued his hot goaltending as the Ottawa Senators defeated the Florida Panthers, 3-1, Thursday night at the BB&T Center.
The Senators are 3-0 and have won 11 of their past 12 games against the Panthers.
Florida, meanwhile, has lost three in a row after a season-opening win. The Panthers scored four goals in their first period of the season. But in the 11 periods since, they have scored just two more.
Senators goalie Craig Anderson is now 9-0-1 lifetime against the Panthers. He spent the lockout working on goalie drills with Canucks star Roberto Luongo, and that plan is working so far because Anderson has allowed just two goals in three games.
On the game-winner, Karlsson scored unassisted with 8:28 elapsed in the second period. He beat Jose Theodore high to his stick side.
Theodore, though, kept the score close, blocking a penalty shot by Guilliaume Latendresse with 10:49 left in the game, and the Senators already leading 2-1.
Jason Spezza added an empty-net goal with 1:16 left in the game.
The Panthers scored first, getting a power-play goal from Tomas Fleischmann with 8:24 elapsed in the first period. His slap shot represented his first goal of the season, and the assists went to Brian Campbell and Tomas Kopecky.
The penalty that gave the Panthers the man advantage was whistled against defenseman Sergei Gonchar, for interference.
But just 14 seconds after Fleischmann's goal, he was sent to the penalty box for hooking. The Senators cashed in on the opportunity, scoring on a slap shot by Chris Phillips, assisted by Zach Smith and Marc Methot.
Fleischmann, who played on the Panthers' top line last season with Stephen Weiss and Kris Versteeg, was without both of those forwards on Thursday. Versteeg (hip injury) has yet to play this season, and Weiss (lower-body injury) missed his first game of the year.
Last season, that trio combined to score 70 of the Panthers' 197 goals.
Versteeg is expected to return Saturday against the Flyers. Weiss' status is not yet known.
The Senators entered Thursday well-rested, having not played since Monday's 4-0 win over Florida.
The Panthers, meanwhile, played their third game in four nights.
NOTES: The Senators have received a boost so far this season from young players such as winger Jakob Silfverberg, 22, who was the MVP of the Swedish Elite league last year and got his first NHL goal on Monday against the Panthers. ... Another Senators 22-year-old on the rise is Patrick Wiercioch, a 6-5, 205-pound defenseman with offensive skills. He had two assists in two games entering Thursday. ... Panthers rookie defenseman Michael Caruso has been put on injured reserve with a broken arm, suffered Tuesday against Montreal. ... Florida will travel 25,059 miles in the regular season, the most of any team in the Eastern Conference. ... Ottawa forward Kaspars Daugavins and defenseman Mark Borowiecki were healthy scratches Thursday and have yet to play this season. But coach Paul MacLean said he expects to use them soon. ... The Senators conclude their Florida swing with a game at Tampa Bay on Friday before returning home to play the Penguins on Sunday. Backup goalie Ben Bishop will likely get his first start of the season against Tampa. ... Up next for the Panthers is a home game Saturday against the Flyers.
