Margie Smith's team, which features Silver Bay's Norma O'Leary, scored six points in the first three ends to ease to victory. The Americans play Russia and Hong Kong today.

"You always want to start out with a win, but we still feel really good about our chances this week," O'Leary said in a news release. "Considering that we came out really strong (Saturday) and had a pretty bad fifth end, we wanted to make sure we didn't let our guard down today."
