Loui Eriksson added an insurance goal into an empty Finnish net with 2.6 seconds remaining in the third.
With the win, Sweden (2-0-0) has a firm hold on the top seed in Group B while Finland (0-2-0) is in tough to advance to the semifinals.
Lundqvist, who missed Sweden’s first game of the tournament on Sunday due to an illness, struggled in pre-tournament competition posting a 4.49 goals-against average and a .778 save percentage in two appearances. The 34-year-old was pulled from last Wednesday’s game against Team Europe after allowing five goals on 22 shots in a 6-2 loss.
Finland’s Mikael Granlund had two excellent chances to tie the game just past the midway mark of the third, but Lundqvist got his right pad on the first shot and Granlund put his rebound off the post.
Things got physical in the third as Finland’s Sami Lepisto caught Sweden’s Mikael Backlund with a questionable, high hit just inside’s Swedish blue line with a little over nine minutes to play. Lepisto was assessed a minor penalty for roughing, while Backlund received treatment on the Swedish bench but stayed in the game.
Sweden nearly added to its lead with eight minutes remaining in the third, but Eriksson put Henrik Sedin‘s feed right into the pads of Rask.
Sweden led 1-0 after two periods on Stralman’s goal. The Tampa Bay Lightning defenceman put a backhand feed from Henrik Sedin past Rask at 9:57 of the middle period.
Finland’s Patrik Laine had an excellent chance to tie the game 1-1 in the final minute of the second, but Lundqvist was able to get his glove on Laine’s one-timer with 40 seconds remaining in the frame.
The two teams played to a scoreless first period with Finland out-shooting Sweden 11-8.
Sweden concludes the preliminary round on Wednesday against Team North America while Finland meets Russia on Thursday.
