Jenny Potter scored three goals to set an Olympic record with her second straight hat trick, captain Natalie Darwitz had five points and the United States routed Russia 13-0 Tuesday in a preliminary-round women's game at the Winter Games in Vancouver.
Twins Monique and Jocelyne Lamoureux also were among 10 goal-scorers for the Americans, who followed up their 12-1 opening win over China on Sunday by routing the defenseless Russians, scoring seven power-play goals and leading 12-0 after two periods.
Jessie Vetter made seven saves for the Americans, who dialed back their attack in the final 20 minutes, taking just two shots in the third.
"All we were trying to do was keep everyone involved and playing," said four-time Olympian Angela Ruggiero, who scored her second goal of the Games. "We still had things we could work on while still respecting our opponent."
The Russians filled the penalty box while trying to keep up with the Americans, and the U.S. kept turning the penalties into power-play goals -- many scored before the penalized player could get comfortable in the penalty box.
The Americans scored five times in the first period and added seven more in the second against Russia's two backups. Anna Prugova stopped 16 shots before Mariya Onolbaeva took over late in the second period with the U.S. up 10-0.
The United States has outscored its two opponents 25-1 in two games. Canada has a 28-1 differential. The two powers in women's hockey are on pace to meet in the gold medal game for the third time in the four Olympiads since the sport was added in 1998.
The Americans scored just 2:19 in when Monique Lamoureux fired a low shot through her twin sister's screen in front for her first goal of the Olympics. Potter then scored a brilliant shorthanded goal, nimbly slipping the puck between defenseman Alena Khomich's legs and breaking in alone on Prugova.
Darwitz's power-play slap shot put the Americans up 9-0 before the midway point of the second period. After Darwitz's shorthanded goal 3:10 later, Prugova was replaced by Onolbaeva -- and Potter finished off her hat trick just 46 seconds later.
The Americans played without forward Erika Lawler, who bruised her ankle in a tumble into the boards Sunday against China. Coach Mark Johnson
expects Lawler to play on Thursday against Finland.
