Hemp was one of six City representatives in the starting XI with captain Steph Houghton, Jill Scott, Georgia Stanway, Keira Walsh and Ellen White also selected, while Ellie Roebuck and Demi Stokes were named on the bench.
Former City ace Carli Lloyd starred to earn victory for the tournament hosts, providing the assist for Christen Press’ opener before sealing the game two minutes later.
The result puts the USA second in the standings – level on points with Spain, who have a Goals Scored advantage following their 3-1 triumph over Japan.
Scott and White were unfortunate not to find the net in Orlando but Hemp earned rave reviews for her impressive performance and was delighted to have achieved her dream of facing the world’s very best on their own backyard.
“It was a really tough match and obviously getting my first start against the best team the world is massive,” she said.
“It’s these games that I want to be playing in, so I loved every minute of it and grew in confidence as the game went on. Now we need to go back to training and recover.
“That’s probably the biggest game I’ve played in, standing out in that national anthem with all the fireworks going off.
“It’s a moment where I was like: ‘Wow, this is what international football is really like.’ I’d love to be in more occasions like that and be one of the stars in the game.”
