WASHINGTON (AP) -Capitals coach Bruce Boudreau saw a troubling trend: His team took too many penalties, and didn't play well when it was a man short.
Alex Ovechkin saw things another way: He thought the officials might have overlooked a call or two that could have gone against the Florida Panthers.
"Sometimes, the referees don't see their penalties," the reigning NHL MVP said. "They see more our penalties."
Either way, the Panthers took advantage of their power-play opportunities Sunday, going 3-for-3 in the first period with goals by Stephen Weiss, Bryan McCabe and Jay Bouwmeester in a 6-2 victory over Ovechkin's Capitals.
"We stunk," Boudreau said. "We got beat to every loose puck. It seemed like they had the puck in the power play for the whole 2 minutes in our zone every time. I can't sugarcoat it, and I can't find excuses for it."
The Panthers turned things around after a 7-2 loss in New Jersey on Saturday, even though they weren't able to properly prepare. Their pregame video session was cut short less than halfway through Sunday because their projector broke.
"We didn't get to go over most of our stuff, including the power play," Panthers coach Peter DeBoer said. "Maybe it's a good thing."
Florida came in having scored on fewer than 15 percent of its man-advantage chances, ranking 26th of 30 NHL teams.
"Maybe that's the secret: We've got to forego the preparation," DeBoer said. "It clicked tonight and hopefully we can continue that."
Michael Frolik, Richard Zednik and Jassen Cullimore also scored for Florida, McCabe finished with three assists, and Weiss had two.
"It was such a boost to our confidence to just get our power play going. It's been so long," McCabe said. "We've been struggling immensely of late."
The Capitals - coming off a rousing overtime victory Saturday at Eastern Conference-leading Boston - heard boos in their building and pulled starting goalie Jose Theodore after falling behind 4-1 in the opening period.
Ovechkin scored his NHL-leading 46th goal with 22 seconds left, and Alexander Semin also had a goal for Washington.
"Lots of mistakes," Ovechkin said.
At Newark, N.J., Martin Brodeur earned his 100th NHL regular-season shutout with a 27-save effort and New Jersey extended its lead in the Atlantic Division to nine points.
The shutout was the second in three games since Brodeur returned Thursday from an elbow injury, and moved him within three of tying Terry Sawchuk's mark of 103. It also was Brodeur's 547th career victory, four shy of Patrick Roy's record.
Brodeur has four shutouts in 13 games this season.
Jamie Langenbrunner, Brian Gionta and Johnny Oduya scored to help the Devils win for the eighth time in 10 games.
The Flyers are 7-3-1 in their last 11 games.
At Calgary, Alberta, Vincent Lecavalier and Martin St. Louis each had two goals and an assist, and Mark Recchi had five assists for Tampa Bay.
Calgary captain Jarome Iginla had two goals and three assists to move into the top spot on the Flames' career scoring list. Iginla reached 400 career goals and has 834 points in 922 games, all with the Flames. He broke the team record of 830 set by Theo Fleury in 791 games.
Evgeny Artyukhin, Steven Stamkos, Ryan Malone and Vaclav Propsal also scored for Tampa Bay. Craig Conroy, Mike Cammalleri, Jamie Lundmark and Todd Bertuzzi added goals for Calgary.
At Dallas, NHL scoring leader Evgeni Malkin had a goal and two assists, Marc-Andre Fleury made 20 saves, and Pittsburgh won its third in a row without injured captain Sidney Crosby.
Malkin assisted on goals by Jordan Staal and Kris Letang, and struck on the power play in the second period. Malkin has 92 points in 64 games.
Miroslav Satan also scored for Pittsburgh, 5-1-1 in its last seven and 2-0 on its five-game trip. The Penguins jumped over Buffalo and Carolina into eighth place in the Eastern Conference.
The Stars lost their season-high fifth straight.
At Chicago, Jonathan Toews, Duncan Keith and Dustin Byfuglien scored for the Blackhawks in the first period, and Antti Niemi made 22 saves in his first NHL start.
Dave Bolland added a power-play goal with 43 seconds left to help the Blackhawks snap an 0-2-1 skid. Chicago has not gone more than three games without a win this season and hasn't dropped more than two straight in regulation.
Anze Kopitar scored for Los Angeles and assisted on Jack Johnson's goal.
At Vancouver, British Columbia, Sami Salo and Ryan Kelser scored power-play goals 1:47 apart late in the first period and early in the second, and Roberto Luongo made 19 saves for his 10th win in his last 11 starts.
Rick Nash, who was in the penalty box for both goals, pulled Columbus within one 6:18 into the third period. Alex Burrows restored the two-goal cushion 5 1/2 minutes later, blasting a 3-on-1 shot over Steve Mason's glove.
The Canucks won for the 10th time in 12 games to firm up their hold on fifth place in the tightly packed Western Conference, moving them four points ahead of the sixth-place Blue Jackets, who have lost three of four.
