U.S. routs Switzerland at women's hockey worlds to set up showdown with Canada

The United States warmed up for its group showdown with Canada by blitzing Switzerland 9-0 at the world women's ice hockey championship on Monday.

The U.S. matched Canada with 3-0 records. Their Group A closer on Tuesday, also in Herning, is expected to be a preview of the final on Sunday.

Czechia also improved to 3-0 after dominating winless Germany 6-0 in Group B.

Heise's pair led the U.S. to 4-0 after the first period.

Knight's pair increased her career tally of world championship points to 83, tied for second in tournament history. Hayley Wickenhesier has the record of 86.

Finland got its first win at Japan's expense, 9-3. Viivi Vainikka had two goals and an assist. The win followed losses to Canada and the U.S.
