Nazem Kadri scored twice, Mikael Backlund had a goal and an assist, and Dan Vladar made 30 saves for the Flames (41-27-14), who ended the season on a four-game winning streak and eight-game point streak (6-0-2).
Despite the late push, the Flames were eliminated from Stanley Cup Playoff contention on Tuesday when the Minnesota Wild and St. Louis Blues secured the two wild-card spots from the Western Conference.
“It’s just a little bit unfortunate that we’re done now,” Flames coach Ryan Huska said. “You know, 96 points usually gets you in [the playoffs], and unfortunately for us this year it didn’t.”
Taylor Ward scored in his NHL debut for the Kings (48-25-9), who will host the Edmonton Oilers in Game 1 of their Western Conference First Round series Monday (10 p.m. ET; ESPN2, SN, TVAS 2, FDSNW). David Rittich made 24 saves.
The game was originally scheduled to be played on Jan. 8 but was postponed because of wildfires that devastated the greater Los Angeles area.
Kadri gave the Flames a 1-0 lead at 2:15 of the second period when he looped around the right side of the net to beat Rittich to the short side.
