The United States rallied to beat Sweden 4-3 at the Hockey World Championship on Monday in Cologne, Germany.

Johnny Gaudreau scored twice, J.T. Compher scored the winner and Jimmy Howard stopped 39 shots as the Americans improved to 2-1 after a surprise opening loss to Germany.

Clayton Keller canceled Elias Lindholm's early score on a power play for Sweden, only to see Lindholm score again.

Gaudreau equalized on a breakaway, but Victor Hedman gave Sweden a 3-2 first-period lead. Gaudreau scored on a brilliant team move involving Jack Eichel and Edina's Anders Lee to tie it again.

Compher put the U.S. in front for the first time with 8:13 left to play.

The Americans stand two points behind Russia in Group A. Russia remained undefeated with a 6-3 victory Monday over Germany. Canada also stayed perfect, beating Belarus 6-0 in Paris.
