The crowd are in full voice every time Kayleigh Powell is touching the ball.
She's showing some electric pace and the line breaks are definitely galvanising the fans who sense this one isn't over just yet despite the battle with the clock as well as the Scots.
Wales 19-24 Scotland
Scotland are doing well to keep Wales pushed far back in their own half.
Not where the hosts want to be if they are to turn this score over in the final seconds.

The bench has really made a huge impact and Wales are back in this.

The atmosphere has just lifted.
Excellent from the young scrum half and Williams with a brilliant finish.

That's why she's Kate the Great!
That's the impact Sean Lynn was looking for, Lockwood with the immediate impact and the talent.
Game on!
Williams, con George
Wales 19-24 Scotland
Wales have a lifeline and it's captain Kate Williams who takes the honours.
Seren Lockwood makes the initial linebreak to get Wales right in front of Scotland's posts and Williams takes it herself from close range and dives under.
Wales 12-24 Scotland

Meryl Smith is the embodiment of the values of this team, she sometimes doesn't get the plaudits.
You can see her stretching that defence and with Wales' dominating the middle field is something Scotland needed.
She's a natural ball player, can play in any position you put her in.
Wales 12-24 Scotland
Wales finally get into Scotland's 22 for the first time since early in the half, but Scotland's defence is rock solid and Holland Brogan gets her hands on the ball to take it off Gwen Crabb.

Wales' defensive has been a little bit narrow, and Scott has absolutely exposed that.
This is something they've identified that there is space out there.

Scott with an absolutely outstanding play.
Missed the World Cup through two broken hands!
Lovely release ball by Bogan and Smith with her right book, what a brilliant finish.
The vision for that, brilliant!
Scott, con Nelson
Wales 12-24 Scotland
Scotland stretch their advantage and it's a super individual score from Lucia Scott.
Centre Meryl Smith boots the ball over the top and Scott runs right onto it before stepping inside around Kayleigh Powell to run clear.
Helen Nelson kicks another conversion to make it a 12-point lead with 12 minutes left on the clock.
Wales 12-17 Scotland

Lockwood is an unbelievable player, and is still only young.
She played in the under-18s' last Six Nations then went straight into the World Cup.
Incredible future ahead.

Seren Lockwood enters the field for Wales for the first time in a Six Nations game.
The scrum-half already has a try at this stadium for Cardiff Quins in the 2023 WRU Girls U16 National Plate Final against Gwylliaid Meirionnydd.
Would be a good time for her to grab another at the Principality.
Wales 12-17 Scotland
More changes afoot first for Scotland as prop Leah Bartlett comes off with another debutant Demi Swann on and try-scorer Shona Campbell is replaced by Lucia Scott.
There's also another for Wales as scrum-half Keira Bevan makes way for Seren Lockwood.
Wales 12-17 Scotland
We've just had an update that Bryonie King's card will stay yellow, which means she'll be allowed back on the field once she's sat out her 10 minutes.

Credit to the ref, it was a head contact, acted swiftly and the game plays on.
Wales 12-17 Scotland
With Bryonie King off the field Sean Lynn instantly makes another change.
Kelsey Jones and Sisilia Tuipulotu go off with Molly Reardon and Donna Rose on to totally switch the front row.
Wales 12-17 Scotland
Referee Ella Goldsmith has called on the TMO to check a tackle and Wales are down to 14 with number eight Bryonie King in the bin for a high tackle on her opposite number Emily Coubrough.
There's also a bunker review ongoing to see if it's to be upgraded to a red.
Wales 12-17 Scotland
Scotland are starting to gain the upper hand in this half, building through the phases to pile some pressure onto Wales' defence.
So far they've not found a way through but Wales have been penned back a bit in the past few minutes.
