Nazem Kadri had a goal and an assist, and Andersson had two assists for the Flames (17-13-7), who lost 2-1 to the Edmonton Oilers on Tuesday. Vladar made 29 saves.
"We hadn't played good the first 40 minutes of the game," Andersson said. "We talked in here that we had to have a good third. We had a couple looks, they had a couple looks, and we managed to get the third one. Then we just battled through the rest of the game, and we managed to get two huge points for the team."
Grubauer made 41 saves, and Jordan Eberle had two assists for the Kraken (18-11-4), who were outshot 44-31 in their second straight loss (0-1-1).
"This team puts a lot of pucks to the net, so we didn't give up a lot of opportunities in the first two periods," Seattle coach Dave Hakstol said. "We gave up a little bit too much in the third. I look at opportunities, we generated a lot of real good opportunities 5-on-5 in the first two periods of the game, the first half of the game in particular. And then in the third period, we gave up a little bit too much again, because we spent too much time in our defensive zone.
"So, I'm not worried about the number of shots. Different teams play different ways. These guys put a lot of pucks to the net from all over the place."
