Jocelyne Lamoureux-Davidson, Brianna Decker and Kendall Coyne each scored twice to lead the United States to a 7-0 victory over Russia at the world championships on Saturday.
Amanda Kessel also scored and Madeline Rooney stopped all 14 shots she faced to give the U.S. its second shutout in two games. Nicole Hensley had 18 saves in a 2-0 win over Canada in the opener the previous night.
Maria Sorokina finished with 27 saves for Russia (1-1).
The Americans scored in bunches, with two goals in less than a minute in the second period and another two in the final 19 seconds of the game.
Kessel, the sister of Pittsburgh Penguins forward Phil Kessel, and Lamoureux-Davidson combined on an odd-man rush with Kessel pouncing on a rebound to score the first goal of the game. It was Kessel's first goal since a 6-1 win over Sweden in the Sochi Olympic semifinal. She missed over a year and a half of hockey after the Olympics due to a concussion.
