Zayne Parekh scored the tying goal in the third period for the Flames (30-34-7), who have won a season-high four straight games. Dustin Wolf made 23 saves.
Yegor Sharangovich scored the deciding goal in the fourth round of the shootout when he attempted to make a move to his backhand but instead slid the puck through the legs of Kings goalie Darcy Kuemper.
“I’m sure he fessed up that he didn’t mean to do that,” Huska said. “I think he was trying to pull it to his backhand, but hey, we’ll take it. It’s a big goal.”
Quinton Byfield scored twice for the Kings (28-25-18), who have lost four straight games (0-1-3). Kuemper made 21 saves.
The Kings are three points behind the Nashville Predators for the second wild card into the Stanley Cup Playoffs from the Western Conference. Nashville won 6-3 against the San Jose Sharks on Tuesday.
“We threw one away, in my opinion,” Kings interim coach D.J. Smith said. “We’ve got one more game on this trip (at the Vancouver Canucks on Thursday). We need two points, and the moral victories (don’t) help tonight. We wanted two points.”
Byfield gave the Kings a 1-0 lead at 2:35 of the first period. Byfield dragged his back foot to stay onside, took a pass from Joel Armia and skated around Flames defenseman Hunter Brzustewicz. He then made a move to his backhand and tucked a shot through Wolf’s five-hole.
“He’s played really well,” Smith said of Byfield. “He’s been our best player. He’s scoring. Every night he’s dangerous and he continues to be skating. He’s playing on all sides of the puck, so it’s as good as I’ve seen him play.”
