USA are making good ground in the England half through their forwards but Abbie Scott and Justine Lucas do well to disrupt the rolling maul and Deven Owsiany just can't get the ball out.

England back in possession as Amber Reed,now at fly-half, punts the ball down field.

USA are flinging the ball about in the backs as Naya Tapper takes the long way round, but Alev Kelter is shoved into touch.

Time for change.

Katy Mclean, Vickii Cornborough, Sarah Bern and Marlie Packer all take their places on the bench.

Rochelle Clark, Justine Lucas, Rachael Burford and Harriet Millar-Mills come on to the field for England.

I was mid-way through a post before that try, about to apologise to you for billing this as a close clash.

England have been utterly dominant in attack but they're still partial to a leaky try or two in defence.

USA are not going down without a fight as they push England way back into their own half.

Safe hands from the women in white at the line-out though, their set-piece has been very tight so far.

England have another penalty - USA captain Tiffany Faaee pulled for collapsing the maul.

I suspect England won't go for the sticks here, they'll want more.

Yep, Katy Mclean goes to the corner and USA will do well to defend another driving maul here...

Middleton will be satisfied with the kicking in this game, it's been much better from England.

Emily Scarratt has been more clinical from the tee and Katy Mclean, back in the fly-half jersey, has controlled the game in the backs.

And just as I say that, the forwards put their hands up and turn the ball over at the breakdown.

Praise all round then.

The players are back out in the sunshine and England are 40 minutes away from a place in the semi-finals.

Just a reminder, New Zealand are already there.

We're back underway in Dublin...

Another 40 minutes to come as England look to hold off USA and book their place in the semis, but the fun doesn't stop there.

Oh no, two more live games for you to follow.

Wales play Hong Kong at 17:15 BST before hosts Ireland face France at 19:45 BST for a place in the semi-finals.

Hours and hours of rugby left yet!

The first ever Women's Rugby World Cup was held in Cardiff in 1991.

But it wasn't without it's challenges.

The organising committee, consisting of two trailblazing women, found they had no money and no support from the rugby authorities.

And when the tournament finally got off the ground, teams turned up in Wales in severe financial difficulty.

The Russians came without any money, and were forced to sell vodka on the steps of the town hall.

But the local community came to their rescue and from small beginnings, women's rugby got off the ground.

Maggie Alphonsi, a 2014 World Cup winner with England, has been to Cardiff to meet the two women behind the first ever tournament.

You can watch the full interview here.

England may be on top in this one, but in the first ever Women's Rugby World Cup, they were beaten by USA in the final.

The year? 1991.

Here's how that tournament came about...

In case you're just joining us, England lead by five tries to one at half-time.

Emily Scarratt's try, a penalty try, two from Marlie Packer and Katy Mclean's score on the half-time whistle gave England a healthy lead at the break with USA crossing just once through Kate Zackary.

I said this could be a classic...but USA are being outclassed so far.

England kick the ball out from the restart, they've had enough and off they trot for half-time.

That has to be their best half of rugby so far this tournament and they've got one foot in the semi-finals.

England are looking to hit straight back but USA have stepped up their defence and Danielle Waterman is ushered into touch.

USA take a quick line-out, they're playing with greater intensity now, but that's a loose pass out wide to Naya Tapper and the move breaks down.

That's a poor clearance from Katy Mclean as her kick misses touch and is collected by Cheta Emba.

USA are inside England's 22 and looking dangerous.

Wing Kristen Thomas powers towards the line put a brilliant effort from at least three England players holds her up on the line.

But they'll come again, England's defence being tested here...

Half an hour played and England lead by 28 points.

But USA, who are yet to grace the world champion's 22, are back to full compliment.

Head coach Pete Steinberg likened this game to the US revolution.

They'll need a mighty revolution to come back from this...
