Mike Richards and James van Riemsdyk also scored for the Flyers, who have won seven of their last eight games.

Van Riemsdyk, the rookie left winger who has at least a point in 12 of his first 15 games, gathered a rebound of Braydon Coburn's shot that caromed off the backboards and backhanded the puck into the net on the power play, giving the Flyers a 3-1 lead with 18 minutes, 13 seconds left.

The Kings made the score 3-2 when Drew Doughty whipped a one-timer past a screened Boucher on the power play with 7:51 remaining.

It marked just the second time this season the Flyers (12-5-1) had won after trailing in a game. The Flyers won despite being outshot, 39-20.

On Tuesday, Flyers coach John Stevens told Boucher he would get his second start of the season last night, but he kept it a secret from reporters.

The reason?

"It was more about the opponent. I didn't want them to know too early," Stevens said before last night's game. "I didn't want them using it as motivation. . . . But we're not playing Boosh because we think it's a lesser opponent; we're playing Boosh because we think Ray [Emery] needs a rest right now. It's a good opportunity to give Boosh a chance to play."

Making his first appearance since looking shaky in a 4-1 loss to San Jose on Oct. 25, Boucher kept the Kings scoreless for the opening 14-plus minutes.

The Kings, aided by strong forechecking, controlled the first period and had an 11-6 edge in shots. Early in the game, Boucher made a nice stop on former Flyer Justin Williams from the right circle, and a few minutes later turned aside Scott Parse's shot from out front.

Boucher was facing a Kings attack that has lost high-scoring left winger Ryan Smyth for four weeks with an upper-body injury. Alexander Frolov replaced Smyth last night and was on the Kings' top line with Anze Kopitar and Williams.

Kopitar, who entered the night leading the NHL with 32 points, blasted a turnaround shot from the slot off the crossbar with 11:30 left in the opening period. A little over four minutes later, after a turnover by Kimmo Timonen, Boucher stopped a blast by ex-Flyer Michal Handzus from the high slot.

But Boucher allowed a soft goal with 5:07 left in the first period. Jarret Stoll, near the corner just outside the goal line by the right boards, fired a shot toward the net that sneaked past Boucher on the near side, giving the Kings a 1-0 lead.

The Kings missed a great chance to increase their lead when Kimmo Timonen (holding) and Darroll Powe (cross-checking) were called for penalties at the same time, giving Los Angeles a five-on-three opportunity with 1:38 left in the opening period.

Brilliant penalty killing by Blair Betts, Mike Richards, Chris Pronger, Ryan Parent and Coburn limited the Kings to one shot in the final 1:38 of the period.

The Flyers killed the remaining 22 seconds of the two-man disadvantage to start the second period, and finally got their offense untracked when Pyorala scored his first NHL goal to tie the score at 1-1 with 12:08 to go in the middle period.

Jonathan Quick stopped Scott Hartnell's shot, but Pyorala, as he was falling to the ice to the right of the goalie, knocked a backhander into the open net. The 28-year-old Finn had scored the game-winner in a shoot-out, but that doesn't count as an official goal.

Pyorala called the goal "a big relief for me. I have had really good scoring chances before. I don't even want to know how many I've had. But I am glad I got this one tonight."

With 1:05 left in the second period, Richards one-timed a Claude Giroux pass past Quick to give the Flyers a 2-1 lead.

Before the contest, Stevens said Boucher - who suffered a groin injury in a scuffling training camp - could play again during the five-game road trip. The trip includes back-to-back games against San Jose tomorrow - Ray Emery will start that one - and Phoenix on Saturday.

"It gives us options moving forward on this trip," Stevens said.
