Nobody on the Anaheim Ducks looks even slightly comfortable these days, and they’ve got no explanations for their collapse.

Bozak scored two goals, Joffrey Lupul had two assists against his former Anaheim teammates, and the Maple Leafs beat the Ducks 5-2 Sunday night for their fourth victory in five games.

Bozak’s third two-goal game of his career was his second in three games. Such are the rewards of skating on the Leafs’ top line with NHL scoring leader Phil Kessel , who had an assist for his 31st point, and Lupul, who’s tied for second in the league with 29 points in his own breakout offensive season.

“I’m comfortable. I think I can play with those guys,” said Bozak, who has stayed on the top line even with Tim Connolly’s return from injury. “We’ve had a ton of injuries, but guys have stepped up and responded really well.”

Bozak and Clarke MacArthur scored 19 seconds apart in the first period for Toronto, which reclaimed first place in the Northeast Division and sent the spiraling Ducks to their seventh consecutive loss with a sturdy, workmanlike performance to finish a mileage-heavy four-game road trip.

Lupul was impressive in his return to Anaheim, which surprisingly dealt him to Toronto nine months ago shortly after he returned from a full year’s absence due to back injuries. Rookie defenseman Jake Gardiner also played more than 25 minutes for the Leafs, who acquired him in the same trade with Anaheim for Beauchemin.

Joey Crabb also scored, Luke Schenn added an empty-netter from in front of his own goal with 12 seconds left, and Jonas Gustavsson made 26 saves in his fourth straight victory for the Maple Leafs during starter James Reimer’s injury absence.

Corey Perry and Francois Beauchemin scored for the Ducks, who have won just twice in 18 games since Oct. 17. Jonas Hiller made 23 saves for the Ducks, who have only 16 points — the NHL’s second-lowest total — despite the presence of a reigning league MVP, an All-Star goalie and a wealth of elite talent.

With former Ducks general manager Brian Burke watching from the visiting executives’ suite and original Ducks coach Ron Wilson behind the Maple Leafs’ bench, Toronto wrapped up its trip with another strong offensive effort in their only Southern California appearance of the season. The Leafs have scored 25 goals in their last five games, getting an early jump in the race for their first playoff spot since 2004.

In St. Paul, Minnesota, Alex Tanguay and Jarome Iginla had third-period goals to pad Calgary’s lead and help stop a three-game losing streak for the Flames.

Matt Giordano, Lee Stempniak and T.J. Brodie scored during a furious first period, and Mikka Kiprusoff steadied himself after the early barrage to make 19 saves for Calgary.

Cal Clutterbuck and Nick Johnson had goals in those first 9 minutes for the Wild, but goalie Niklas Backstrom was pulled for Josh Harding after the Flames took a 3-2 lead.

Backstrom was yanked from a home game for the first time in nearly two years.

In Ottawa, Jason Spezza scored twice, including his 200th regular-season goal, and David Runblad got his first NHL goal to lead Ottawa.

Spezza reached the milestone with his second goal of the game on a power play late in the first period. His first tally 55 seconds in ended a personal 11-game goal drought.

Zack Smith also scored and Craig Anderson made 34 saves for Ottawa, which is on a 4-1-1 run.

Eric Staal and Alexei Ponikarovsky scored in the third as Carolina twice closed to within one. Patrick Dwyer also had a goal for the Hurricanes and Cam Ward made 21 saves.

In Columbus, Ohio, David Backes scored in the third period to lift St. Louis to the win in coach Ken Hitchcock’s first game against his former club.

Kris Russell, traded from Columbus earlier in the month, also scored for St. Louis, which is 7-1-2 since Hitchcock replaced Davis Payne on Nov. 6.

Brian Elliott made 23 saves for the Blues to improve to 10-1-0 this season.

Derek Dorsett scored and Curtis Sanford made 27 saves for Columbus, which had its five-game points streak snapped.
