Sophia Smith strikes twice as United States cruises past Vietnam at Women's World Cup

Sophia Smith scored twice for the United States in the opening half and the two-time defending champions kicked off the Women's World Cup with a 3-0 victory over tournament first-timers Vietnam on Saturday.

Lindsey Horan added a goal for the favoured Americans, who have won four World Cups overall and are vying for an unprecedented three-peat in this year's tournament.

Vietnam drew comparisons to Thailand, the team the Americans routed 13-0 in in their 2019 World Cup opening game. But Vietnam was surprisingly resilient, kept the game closer than expected, and goalkeeper Tran Thi Kim Thanh stopped Alex Morgan's first-half penalty attempt.

Morgan was knocked to the field clutching her calf after trying for the rebound off her missed penalty, but she quickly returned. It was just her second penalty miss for the United States.

Smith, one of 14 Americans playing in their first World Cup, showed why she was named both U.S. Soccer's Player of the Year and the National Women's Soccer League MVP last year with her two first-half goals.
