United States launched their bid for an unprecedented third consecutive world crown with a comfortable win against Women’s World Cup debutants Vietnam in Auckland.

Smith, one of 14 players in the squad appearing at their first World Cup, fired the number one ranked team in the world ahead with a low drilled finish from an angle.

Her second was awarded following a lengthy check by the Video Assistant Referee for an offside before captain Lindsey Horan, after an assist by Smith, swept home the third in the 78th minute.

There was a memorable moment for Vietnam keeper Tran Thi Kim Thanh when she was mobbed by her jubilant team-mates after keeping out Alex Morgan’s penalty which was awarded for a foul on Trinity Rodman.

Vietnam rarely managed to get out of their own half but they worked hard and produced a gritty defensive performance to keep the scoreline respectable.

Bigger tests to come

While this was not the hammering some had predicted in the build-up, the United States did enough to get their campaign off to a winning start.

Four years ago in France they recorded the biggest ever Women’s World Cup win, a 13-0 thrashing of Thailand, in their opening game on the way to winning the tournament.

They carved out enough chances against Vietnam to record another double-digit win and there was a tinge of disappointment from boss Vlatko Andonovski that his side did not make the most of their 28 attempts.

The USA arrived in New Zealand as favourites but tougher tests lie ahead and only after Thursday’s match against the Netherlands in Wellington – a repeat of the 2019 final – will their fans learn more about whether they can make it three World Cups successes in a row.

This was so comfortable that Andonovski sent on 18-year-old Alyssa Thompson for her first taste of the World Cup, while fellow substitute and icon Megan Rapinoe also made her 200th appearance for the Stars and Stripes – 17 years to the weekend she made her debut.

Rapinoe had a chance to mark the milestone with a goal but failed to take her chance, while Rose Lavelle struck the bar in the closing stages.

Women’s World Cup alive with colour

Eden Park was awash with colour as the defending champions launched their bid for a fifth world title.

There was red, white and blue all around the ground as thousands of fans, who had travelled thousands of miles from the United States to be in Auckland, watched their team get off to a solid start in New Zealand’s national stadium.

Chants of “USA, USA, USA,” broke out around the ground at regular intervals, while some supporters came dressed up as the Statue of Liberty. Others wore shirts with ‘Rapinoe’ on the back and one couple even brought their baby to the match.

There was also a good luck message from former US President Barack Obama before the match.

“You represent the best of the best, and I’ll be cheering for you all the way,” he wrote on social media.

Inside the ground there were patches of red as Vietnam’s expat community turned up to watch a moment in their country’s sporting history, with it being the first time the nation had appeared in a Fifa men’s or women’s World Cup.

Vietnam were organised, tenacious and disciplined but they did not test Alyssa Naeher once despite neutrals in the crowd roaring each time their players crossed the halfway line.
