The Black Ferns are not worrying about rotation.
For the third consecutive test in the Women's Super Series in Canada, they are fielding the same line-up, though wing Renee Wickliffe's inclusion in the team is subject to fitness testing and Janna Vaughan will replace her in the No 11 jersey if required.
Vaughan would be replaced on the bench by Keri Hayden of Manawatu. Should that occur, it would still leave two players - prop Sosoli Talawadua and halfback Arihiana Marino - with no game time on the tour.
The match against the USA in Edmonton this morning follows the Black Ferns' win over world champions England (26-7), and Canada (40-22).
The victory over England was well merited, showcasing some staunch defence and an ability to soak up a heap of pressure from the reigning Women's World Cup holders, though England were very disappointing on attack and the match itself was a turgid spectacle.
Should the veteran 37-year-old halfback Emma Jensen come off the bench, she will draw level with Anna Richards (on 49) as the most capped Black Fern in history.
Head coach for the tour Glenn Moore said the focus for the team is now to finish the job and win the tournament.
"We came here to try and win the three games and that's certainly what we're after and if we get a trophy on the end of that then that's great."
Moore said the atmosphere among the team was very positive and he'd been impressed with the team's work ethic, from players through to management.
"You could start to see that building before we even played a game, to be fair. It's a good environment with a good culture and I think you can see that coming through on the field."
USA, who placed sixth at the 2014 World Cup, losing twice to the Black Ferns, are coming off a 36-28 win over hosts Canada.
The game will be live streamed from 10am.
