Fresh from their stunning second-half fight back - or indeed fight backs - v Australia, USA know they have to hit full throttle from the whistle. With a current points difference of -62 versus Australia's of +73, the Women's Eagles know they need a huge victory against Samoa before hoping England do them a favour later in the day. Full details here.
Despite the scoreline, Samoa did enjoy a strong 10 minutes at the start of the second half v England, and they will be looking to get their big runners in to the game far earlier against USA. A first try of the tournament would be celebrated wildly by a side that sits at No.15 in the world rankings.
Kick-off: 13:30 BST, Saturday, 6 September

USA team:
USA's key player: While there is so much focus on her admirable off-field activity, there is no doubt Ilona Maher has been on a hit on the pitch so far at RWC 2025. Two turnovers in the first 20 minutes v Australia helped set the tone, and so far Maher has not taken a single backwards step. Expect a whole heap more direct running from the star centre.
Samoa team:
Samoa's key player: Harmony Vatau slotted Samoa's only RWC 2025 points so far, v England. But the inside-centre is not only a kicker, with three off-loads and several line-breaks, she is the linchpin of a backline that can dazzle.

What USA said:
USA head coach Sione Fukofuka:
"Our physicality (v Australia) was outstanding; we asked them for it and they stepped up in spades. They dominated collisions, they played a really good platform and obviously created opportunities to score points and took a few of them themselves. They’ve been consistent and we’re really happy with the combination we’ve got out there."
USA captain Kate Zackary:
"Mood's been really good. We adjusted a little bit of our training this week just because Saturday was a huge match, physical match as well.
"So a bit of community engagement on Monday, which lifted spirits, being involved with the local rugby clubs, youth, and some women's teams reinvigorates the ‘why’. You have to remember why we do this: we don't do it for the money, we do it for the passion.
"Tuesday's training was one of our biggest and heaviest combat days. We joke it's the hardest day of the week, because we purposely make it harder than a Saturday. And that put people up for selections.
"Then Thursday was fast and it was furious and it was a really good session.
"We want to empower everyone to showcase their X factor, but it's an 80-minute game and we don't need any heroes. As a team, we need 15 or 23 people collaborating constantly to create opportunities. We're not chasing anything this week and I think that's the biggest message: we're going to be the creators of our own destiny."
What Samoa said:
Samoa head coach Ramsey Tomokin:
"We want the girls to express themselves and show who we really are. We showed last week who we were, but we can show more, and we want to finish strong.
"We understand the equation: USA needs points, and we're going to make that very difficult for them. We're targeting to try and win and get some points, and put pressure on them. They'll be chasing points, and hopefully that will translate into us getting our own points. I sent a message to the Australia camp, saying we're going to do our bit for the region.
"I heard their coach saying they'll stick to the plan and process, and the rest will take care of itself in terms of points, so our plan and process is to do the exact opposite of that. Stretch them out a bit and put them under pressure.
"It's another opportunity to play a tier-one team. We had a good game with them a couple of years ago, and I believe we have the players to match them."
