PYEONGCHANG, Feb. 12 -- An unified Korea team was crushed by Sweden 8-0 on Monday night in women's ice hockey preliminaries at the PyeongChang Olympic Games while the Sochi bronze winner Switzerland beat Asian champion Japan 3-1 to top Group B with two wins.

Eight teams are divided into two groups for competition in PyeongChang. In Group A, defending champion was ranked the first place followed by the Sochi silver medalist United States. Finland came in the third before Olympic Athlete from Russia on goal difference.
