HELSINKI (AP) Craig Smith had a hat trick and teenager John Gibson was stellar in net to lead the United States over host Finland 4-1 at the ice hockey world championship on Wednesday.

Gibson, who finished with 31 saves, was a bold choice which paid off for the Americans, who moved above Finland in their group second to Russia.

Though the 19-year-old has primarily played junior league hockey in Canada, he's a three-time world age-group champion. He's won titles in the under-17 classification, under-18, and at this year's juniors in Russia, where he was named the most valuable player and best goalie.

In other matchups, Switzerland won its fourth straight game, beating Slovenia 7-1; Sweden stuffed Norway 5-1; and Germany posted its first win, 2-0 over Austria.
