The Italians stamped their mark on the game with four tries - even when they were a player down in the third quarter.
They sensed early in the second half that if they tire out the Americans, they were in with a chance.
USA started the game strongly, pinning Italy in their half and got on the scoreboard in just the third minute through lock Hallie Taufoou following multiple phases of play as the USA looked to unsettle the Italians through quick phase ball.

The American ball carriers bashed and crashed up the middle but began to tire out as the game wore on.
They did not lack support in the stands and a number of American flags were seen flying on the grandstand and the embankment side as well.
In fact, US players Tess Feury, McKenzie Hawkins, Gabby Cantorna, Carly Waters, and Hope Rogers had a group of hardcore fans in the crowd as their parents have made a trip across the globe to cheer their daughters on.

Tom and Kim Feury, Jay and Kim Hawkins, Valerie Waters, Margherita and Bernie Cantorna, and Chris Waters are excited to see their daughters in action.
The group, who reckons the USA have done amazingly well to make it here, hope the team put in some strong performances.
They tip them for an upset along the way.
"A final against the Black Ferns would be great [...] and anything can happen from there," Tom said.
While the team's supporters, like all spectators, applauded the skills and pace of the game, they must have been bitterly disappointed at the result.

The USA has an impressive track record dating back to 1991 when they were crowned tournament champions, and later runners-up in 1994 and 1998. They made the semifinals at the last event before losing to the Black Ferns.
For Italy, it was just the perfect start to the only match they played in this tournament in Whangārei.
They are physically not as big as the Americans but the Italians' tackle completion was good and they minimised their mistakes after the breather which allowed them to put the opposition under intense pressure at times.

Both teams were guilty of a number of unforced errors but the Italians took their opportunities well in the second half and came away with a good win.
Italy scored at the stroke of halftime through fullback Vittoria Ostuni Minuzzi and led 7-5 at the breather.
A moment no doubt celebrated by the fullback's parents who were in the crowd. Martina Busato and Ostuni Minuzzi, from Padva, made the journey to Whangārei to watch Minuzzi represent the Italian side.

They were with pal Antonio Pasquale, a Russell local since 1995. His early predictions that the Italian side would perform to their best proved true.

Their last try was a pearler. A classic set-piece move. The Italians won their lineout before a brilliant inside pass by their No 10 Veronica Madia to wing Maria Magatti who beat three tacklers down the blindside to score.
The second match is underway with Canada taking an early lead over the lower-ranked Japanese team.
The early advance is a welcome delight to the family of Canadian Rugby team captain Sophie de Goede, who was being proudly cheered on by her family within the crowd.
de Goede was good at many sports growing up, but it was perhaps inevitable that she'd end up playing rugby and captaining her national team.
After all her dad, Hans de Goede, captained Canada in two Rugby World Cups - the first on New Zealand soil in 1987 and the second in 1995.

But rugby also runs through the blood of de Goede's mum, Steph White, who captained the Canadian women's rugby team in two Women's Rugby World Cups in 1991 and 1994.
"Sophie is a great athlete who was good at many sports but we were so pleased she landed with rugby and it's taken her to the highest points in the game, playing here against the best women players there are," White said.
"We're so proud of her."
Hans said his daughter was always hanging around the game as a child.
"And best of all we get to travel around the world to all these amazing places to watch her play."
"I've learned how to do poi, which is brilliant, and the singing and playing with the conch shells is just so haunting and beautiful, I've been blown away by it."
Earlier fans were greeted by the sounds of a kapa haka group performing on the field ahead of the opening game.

The excitement will be further fuelled when celebrated Kiwi artist Ladi6, whose real name is Karoline Tamati, lights up the stage later in the afternoon.
The world cup kicked off in full last night at Eden Park in Auckland where the Black Ferns and Australia put on a nail-biting show.

While the Ferns' 41-17 win over Australia is impressive on paper, it was a tale of pure grit as the team had to fight back from 17-0 in Australia's favour.
Although showers doused the district earlier this morning, the MetService weather forecast wouldn't dampen the spirits of rugby fans visiting the district.
MetService meteorologist Dan Corrigan said the light showers, warm temperatures, and a gentle breeze were in store for rugby fans and players this afternoon.

Adding to the promising day is the potential for fans to enjoy a feast of international food available in the Festival Zone in the events centre.
While most of the action is on the field there is plenty of entertainment off-field in the Fan Zone to keep the kids happy.
Scott and Kate Davies, from Taurikura in Whangarei Heads, checked out the Fan Zone with their daughters Riley, 5, and Aria, 2, during the half-time break in the opening match.

Scott said having the world cup in Whangārei was brilliant for the city.
"For rugby and sport in general, but particularly women's sport it's great to have an event like this here. Hopefully it will inspire the next generation of players."
People could also enjoy the feast of delicious international food available in the Festival Zone and in the concourse. Free water is available at the fountains in the concourse.
