Andreas Granqvist converted a penalty in the 65th minute to hand Sweden its 1-0 victory over South Korea.
The Sweden captain earned the penalty after the referee made a review of the on-field video and declared a foul.
Sweden takes the second spot in group F behind Mexico who stunned the defending champions Germany last Sunday.
This is the first time that Sweden has won its World Cup opening match since 1958.
Granqvist was honored with the Man of the Match title.
