Team USA takes on Vietnam to kick off World Cup

Overnight, the U.S. Women's National Soccer team kicking off their quest for a third straight World Cup championship with a win against Vietnam. ABC's Maggie Rilley is in Auckland with all the highlights. Maggie, good morning. Hey, morning. Yeah, what a win for Team USA. We were there. It was an absolutely packed stadium. We met so many fans that traveled all the way halfway around the world to be here from the U.S. We saw huge crowds of fans there for Vietnam. We also heard quite a few Kiwi accents because, guys, you know what? When the U.S. Women's team shows up, everyone comes out to witness their greatness. The two-dime defending World Cup champs, Team USA, launching their quest for the three-peat tonight. The red, white, and blue dominating an overmatched Vietnam team, 3-0. In her World Cup debut, 22-year-old Colorado native Sophia Smith whipping the ball past Vietnam's goalie in the 14th minute. The number 11 announcing her arrival on the biggest stage of them all in spectacular fashion. You had told us that you were here just to get a job done, and I feel like, girl, today, you out there, you got that job done. It has to be an extra boost of confidence going to the rest of the World Cup. Oh, yeah, it's always good to start off on a good note, and feeling confident, feeling good as a team. That's what we want going into, you know, these next few games, but especially the next one. We know it's not going to be easy, so it's a good place to start. The U.S. women controlling possession over a scrappy Vietnam team. The Asian nation making its first-ever World Cup appearance. But the Americans missed several chances to score even more goals, including this attempted penalty kick by star striker Alex Morgan. With so much at stake for the U.S., the mood was sometimes tense in a packed Eden Park Stadium. But the crowd erupted when two-time World Cup winner Megan Rapinoe came in as a substitute in the second half. This was the soccer legend's 200th appearance for the U.S. team. It's very special being able to play in a World Cup. It's very special knowing this will be my last with this incredible team. And, guys, with those two goals, Sophia Smith became the first U.S. women's team player ever to score multiple goals in her U.S. World Cup debut, just an incredible thing to witness, guys.
