Jordan Eberle and Oliver Bjorkstrand also scored for Seattle (29-29-13). Eberle’s goal was the 299th of his career and 17th this season.
Joey Daccord made 13 saves in his third shutout for the Kraken, who went 0-6-2 in the previous eight games — seriously dimming their playoff hopes. Seattle also went 0-6-2 from Nov. 24 to Dec. 10 this season.
The Ducks (24-44-4), already eliminated from playoff contention, lost for the ninth time in 10 games.
Ducks goalie John Gibson stopped 32 shots.
Tolvanan put the Kraken up 1-0 at 7:50 of the first period. Beniers dug out the puck from behind the net and found Tolvanen at the top of the crease, and he scooped it past Gibson.
Eberle scored on the power play at 16:51, firing a shallow shot that deflected off Gibson’s stick and behind him into the other side of the net.
That marked the first time in four games the Kraken managed more than one goal. Their previous multi-goal game was a 6-2 home loss to Buffalo on March 18.
Bjorkstrand scored on a power play at 5:08 of the second. Beniers made it 4-0 at the 15:55 mark.
