And that brings to a conclusion our coverage from Brighton. A job well done for Samoa.

Next up is Wales v Uruguay at the Millennium Stadium, which you can follow now by clicking here.

We'll see you there!

Victory lifts Samoa above Japan to the top of Pool B. Scotland, who play the Brave Blossoms on Wednesday, are the only team in the group yet to see any 2015 Rugby World Cup action.

United States' AJ MacGinty was successful with his two penalty attempts, but missed both conversion attempts. If he had kicked one of them his side would have earned a losing bonus point.

George Clancy brings to a close this second Pool B match to a close. Tries from Tim Nanai-Williams and Ofisa Treviranus give Samoa victory over the United States.

And, in keeping with the theme of the game, a States forward infringes coming off his feet at the breakdown.

The match is Samoa's.

Samoa have the ball back again though, inside their own half and working through the phases.

They look to wind the clock down.

Samoa gather the restart, but are soon enough penalised for not releasing.

AJ MacGinty boots to touch. The United States have three minutes or so to at least rescue a losing bonus point.

Want to know why the United States are trailing? Well, one of the reasons is the fact they have conceded 11 penalties (red and black circles) compared to only four from Samoa.

The line-out is good, the States are two metres from the line and with a penalty advantage.

Can they make it count? They need to make it count...

We have seen a lot more from the American backs in the second half, even if the scoreboard doesn't reflect it, as Thretton Palamo beats the first tackle and offloads. 

The United States are into the 22 - and win a penalty for a deliberate knock on by Alesana Tuilagi.

This time they head for touch.

United States concede their 11th penalty(!) of the match, which replacement Mike Stanley superbly lands from around 40 metres on the angle. Excellent kick.

That's remarkable from USA wing Takudzwa Ngwenya, who runs fully 40 metres plus unchallenged - but from one side of the pitch to the other, making hardly any ground whatsoever.

Samoa come back through Alesana Tuilagi, who completely piles through a Chris Wyles tackle. The sort of run that has become his brother Manu's trademark, but has always been Alesana's.

That's superb defence from Samoa, as a couple of players halt the progress of Thretton Palamo and manage to hold the American centre up, earning themselves the put-in at a scrum.

"Swing low, sweet chariot" echoes around the Brighton Community Stadium. Can the United States muster a challenge to this Samoan dominance?

They don't James, they really don't.

With 20 minutes left, Samoa's Ofisa Treviranus has already made 13 carries. The most by any player in the first five matches of the World Cup was Schalk Burger's 18 during South Africa's 32-34 defeat by Japan on Saturday.

All the while, Takudzwa Ngwenya has knocked on for the United States so Northampton Saints scrum-half Kahn Fotuali'i will insert at a scrum.

Speaking before the match, Samoa prime minister Tuilaepa Sailele Malielegaoi said his side could go all the way at the World Cup.

"The thing is we should make the quarter-finals,” said Tuilaepa, who is also the president of the Samoa Rugby Union.

Speaking to the Samoa Observer,, external he added: “If we reach the quarter-finals, there is nothing stopping us from the reaching the semi-finals and so forth… you never know, we might get lucky.

“We can never discount that possibility.”

So far, so good today, anyway.

That's a little unlucky from Tim Nanai-Williams, who spilled the ball but then brilliantly recovered to gather before it lands.

At least that's how I saw it - but referee George Clancy decides he knocked it on so the packs will scrum down.
