Backlund then scored into an empty net at 19:52 for the 4-2 final.
After a scoreless first period in which Calgary outshot Seattle 18-6, Stephenson gave the Kraken a 1-0 lead at 7:52 of the second period, extending his goal streak to three games.
While cutting towards the net through the left circle, Stephenson took a pass from Eeli Tolvanen on his backhand before tucking a forehand shot just inside the far post by the outstretched left leg of Wolf.
Backlund tied it 1-1 at 10:20, driving hard to the net before a shot by Andersson deflected off his skate and past Daccord.
“We weren’t happy being down,” Backlund said. “You can tell the guys were feeling good and playing well and we were believing that we were going to come back and win.”
Kakko put the Kraken ahead 2-1 at 17:16 with a power-play goal, redirecting a pass from Ryker Evans.
“In the end, you’ve got to find a way,” Kakko said. “These are the games you’ve just got to win. We were winning and, like I said, you’ve got to find a way.”
NOTES: Andersson recorded his second three-assist game of the season, having also accomplished the feat in a 5-2 win at the Vancouver Canucks on Nov. 23. Mark Giordano is the only Flames defenseman with more three-assist games in a season in the past 30 years (three times in 2018-19). … Stephenson extended his point streak to seven games (four goals, three assists).
