Mike Richards had a goal and an assist for the Los Angeles Kings, who spoiled Mike Cammalleri's anticipated return to the Flames with a 4-1 victory over Calgary on Saturday night.
The victory, which snapped the Flames' eight-game, home-winning streak, gave Darryl Sutter bragging rights over brother Brent in their first meeting as NHL head coaches.
Matt Greene, Anze Kopitar and Dustin Brown into an empty net also scored for Los Angeles (22-15-8), which kicked off a three-game road trip.
Cammalleri had his 10th goal of the season in his first game back with the Flames (21-20-5) since being reacquired in a trade with Montreal on Thursday.
It was Calgary's first regulation loss to Los Angeles at home since Dec. 21, 2005 (10-1-1).
Darryl Sutter, who stepped down as Flames general manager in December 2010, is 7-1-4 since replacing Terry Murray as Kings coach on Dec. 17. He had taken over as Calgary coach during the 2002-03 campaign and added the GM title the following season.
