Jarome Iginla assisted on goals by Tony Amonte and Daymond Langkow, and Kristian Huselius scored on a breakaway in the third period for Calgary. Jamie McLennan made 27 saves in his third start of the season.
It was a well-deserved night off for workhorse Miikka Kiprusoff, who has not allowed more than three goals in any of his last 24 starts since giving up five goals in consecutive road losses against Toronto and Montreal.
Rookie Anze Kopitar had two goals and an assist for Los Angeles and Dustin Brown scored on a power play.
The Kings play five of their next six on the road – including Thursday night at St. Louis when they face former coach Andy Murray for the first time since he replaced Mike Kitchen behind the Blues’ bench on Dec. 11.
Calgary left-wing Alex Tanguay missed his first game of the season because of a charley horse and was replaced by Amonte on the Flames’ top line alongside Iginla and Langkow.
Amonte opened the scoring at 1:24 of the first period when he got the puck from Iginla in the neutral zone and caught Dan Cloutier napping with a seemingly harmless slap shot from just behind the blue-line that deflected off the goalie’s glove. The goal came while Scott Thornton was off for holding Andrew Ference.
Cloutier, the target of boos at Staples Center all season because of his erratic play, was burned again less than three minutes after Amonte’s goal on another long shot by Regehr through a screen as teammate Chuck Kobasew got tied up with Kings defenceman Aaron Miller in front of the crease.
Kopitar twice cut Calgary’s lead to one goal. His first score came just 36 seconds into the second period when his attempted centring pass for Brown caromed into the net off McLennan’s blocker. Kopitar got his 10th of the season at 14:34 of the period, converting Jeff Cowan’s pass from behind the net after Langkow’s 13th goal gave the Flames a 3-1 advantage.
Moss, making his NHL debut after four seasons with the University of Minnesota and almost 1 1/2 seasons with Omaha of the AHL, increased the margin to 4-2 at 17:16 of the second with a redirection of Dustin Boyd’s centring pass. The assist was Boyd’s first point in the NHL.
Notes: Regehr, playing in his 19th NHL game and fifth this season, is the brother of Flames defenceman Robyn Regehr. Robyn was born in Recife, Brazil. Richie was born in Bandung, Indonesia. . . . The Flames, who lost 4-1 at Anaheim on Monday, have played the Ducks and Kings in back-to-back road games on 21 occasions since Anaheim joined the NHL in 1993-94. The only time Calgary left town with a sweep was in February 1994. . . . The Kings have allowed at least one power play goal in 10 straight games since killing off all five Calgary power plays in a 3-1 victory on Nov. 25 at Staples Center. . . . McClennan allowed four goals in each of his other two starts – both on the road, against Columbus (Nov. 3) and Anaheim (Nov. 26).
