TORONTO -- The Florida Panthers are starting to make steady progress in the Eastern Conference.
The Panthers won their fourth straight and sixth in their past seven games.
With the victory, Florida moved within six points of Toronto in the Eastern Conference.
"We're looking for progress," coach Peter Horachek said. "We're looking for consistency in our play."
Mason Raymond scored for Toronto, which lost for the fifth time in their past six games.
The Maple Leafs, who played Monday night in Pittsburgh, did not want to use fatigue as an excuse.
"There's never an excuse: Injuries, tired," goaltender James Reimer said. "Those are all excuses. They're useless."
Raymond said that he and his teammates "simply got embarrassed."
The Leafs committed turnovers that led to all three Panthers goals and were never really able to keep up.
"I echo those remarks as something that we cannot be proud of our performance tonight," coach Randy Carlyle said.
"We just didn't play well enough. That's the bottom line," Leafs captain Dion Phaneuf said. "We take pride in being a team that doesn't get outworked. Tonight we were outworked."
Center Nazem Kadri was the first Leafs player to make a costly error. He lost the puck at the Panthers blue line. And seconds later, Fleischmann had a jump on Carl Gunnarsson and beat Reimer to make it 1-0 just 3:29 in.
Sloppy play continued, but it didn't hurt the Leafs again until a poor defensive-zone shift in the second. Defenseman Jake Gardiner put the puck right on Bergenheim's stick, but Reimer made a stop to keep the threat at bay.
When the Leafs couldn't clear it, Bergenheim got it back in front and scored 5:54 into the second.
"We had clear-cut possession of the puck, won a faceoff, it goes back to (Gardiner), they end up with a breakaway out of it," Carlyle said. "It's pretty hard to defend a player in that position, and I told him so. You've got to expect to have a higher level of execution than that in that situation."
Phaneuf's turnover contributed to the Panthers' third goal. Boyes poked the puck away from Phaneuf and scored seconds later on his own rebound thanks to some help from Bergenheim in front.
"I made some mistakes tonight that are unacceptable," Phaneuf said. "Take responsibility for it."
The Leafs cut it to 3-1 not long after on their most opportunistic play of the game. Center Peter Holland, filling in amid injuries to Dave Bolland and Tyler Bozak, held onto the puck long enough to get some traffic in front, and Raymond tipped the puck past Clemmensen 3:43 into the third.
"I thought we got a little life after that," Raymond said. "We played some better hockey then."
Carlyle didn't like the lack of second opportunities.
"I classified our game as we tried to plan shinny against an NHL hockey club tonight," he said.
Clemmensen made 28 saves for the victory.
The veteran goalie acknowledged, as did Horachek and other Panthers players, that the Leafs were tired.
But it was incumbent on the visitors to take advantage of that.
"We were hoping to have a little bit more energy than they had," Clemmensen said. "Fortunately for us, we kept them off the board until the third period. That, in turn, kept the crowd out of it. That was big."
This was their third victory in the past two weeks against a team being featured on HBO's "24/7" program. Florida beat the Detroit Red Wings on Dec. 7 and Dec. 10.
The Leafs are looking to get things going in the right direction.
"Everyone is trying to turn it around," center Jay McClement said. "It seems like we need all of us to step up and take the reins and change things. But it seems like we're waiting too long to do that."
Center Trevor Smith broke a bone in his right hand when blocking a shot from the Panthers' Shawn Matthias in the third period, Carlyle said. Smith has four goals and five assists in 24 games this season. ... Last year's Calder Trophy winner, Jonathan Huberdeau, missed his second straight game with a foot injury. Horachek said he could have played and is hopefully on target to be in the lineup Thursday when Florida visits the Ottawa Senators.
