Tomas Vokoun earned his fourth shutout of the season and rookie Evgeny Dadonov had a goal and an assist to lead the Florida Panthers to an easy 5-0 win over the Philadelphia Flyers on Monday night.
Bill Thomas, Shawn Matthias, Mike Santorelli and Dmitry Kulikov also scored for the Panthers, who won for the fifth time in seven games and stopped the NHL's top team.
The Flyers lost in regulation for the first time since being shut out by Boston on Dec. 1, a rare hiccup during a month in which they had secured 15 of a possible 18 points through their previous nine games, streaking to a league-leading 22 wins and 49 points. Philadelphia entered having won seven of eight.
Vokoun's fourth shutout tied him with Carey Price for third in the league, one behind Boston's Tim Thomas and the New York Rangers' Henrik Lundqvist. It was the 42nd shutout of Vokoun's career, and his first against the Flyers in 17 starts.
Vokoun stopped 26 shots. Philadelphia had only 16 shots on goal through the first two periods.
In the team's previous meeting this season, the Flyers cruised to a 5-2 win on Nov. 13, as Mike Richards and Claude Giroux each scored twice and Sergei Bobrovsky stopped 34 shots.
Bobrovsky, a rookie, wasn't anywhere near as effective Monday in just his second start in six games.
The Panthers scored twice in the final 2:33 of the opening period. Thomas scored first at 17:27, when his shot from below the right faceoff circle deflected off the left knee of Oskars Bartulis and over Bobrovsky's shoulder.
Less than 2 minutes later, Dadonov scored on a breakaway, beating Bobrovsky to the left side.
Matthias made it 3-0 in the second period. Marty Reasoner's shot hit the post and bounced to Matthias, who easily flipped it in the net. Bobrovsky's night ended when Sean O'Donnell slipped collecting the puck in his own zone and Steve Bernier made a cross-ice pass to Santorelli, who fired a one-timer past Bobrovsky.
Bobrovsky stopped 18 of 22 shots. Kulikov scored the final goal against Brian Boucher with 8:25 left.
Florida, which has outscored its opponents 11-2 in the past two games, was coming off a 6-2 win over the Buffalo Sabres on Friday.
NOTES: Reasoner has 150 career assists. ... Philadelphia is 38-24-7-1 against the Panthers.
