Former Wales coach on BBC Radio Wales
Very much game on and that's credit to Wales there, it was about building pressure and taking advantage there.
The props were titanic last season and they've got to make sure they're using them.

If I was Hannah Jones I'd be asking when there will be a yellow card here after those penalties over the last five minutes.
Sisilia Tuipulotu try, Keira Bevan
It had to come and it's in the familiar shape of Tuipulotu.
Fellow prop Gwenllian Pyrs went had the first go from a tap penalty,, but really she was just teeing it up for Tuipulotu to barge over from close range.
She scored four tries last season and is off the mark again in the first game.
Sisilia Tuipulotu scores try from close range to bring the score to 13-17 to Scotland.

Kelsey Jones came within inches of a score.
Scotland hold out but it's another penalty and captain Rachel Malcolm is getting a warning from the referee.
Wales 6-17 Scotland
Wales within touching distance of the Scottish line.

However penalties adding up here and Wales edging up field.
They need a score.
Wales 6-17 Scotland
Scotland have ben so mush more effective with the ball and have made almost 300 metres so far - more than double Wales' 122.
Says it all really.
Wales 6-17 Scotland
I think they were listening Chris.
Carys Cox on for teenager Nel Metcalfe.
Wales certainly need something.

Chris Horsman
Former Wales coach on BBC Radio Wales
There's no fluidity about what Wales are doing, it's all a bit paint by numbers.
It's very predictable, coming round the corner, there's no deception in it.
They're not dictating the pace, Scotland are as and when they need to.

Great kick by Lisa Thomson here, Scotland are winning that kick battle.
The 50-22 really rewards good tactical kicking.
Wales 6-17 Scotland
Scotland are really growing in confidence.
Meryl Smith shows a clean pair of heels to run out of defence.
Wales kick it back but centre Lisa Thomson pings a 50-22.
Scotland on song here.
Wales 6-17 Scotland
There's a small but very noisy enclave of Scotland fans over the other side - they've loving this, and why not.

Absolutely superb play, it was Evie Gallagher's work off the floor that set that up.
Emma Orr realises that the Welsh defence are pushed up and she goes round on the edge of them and sets up the two on one.
Rhona Lloyd did well there, little hurdle at the end, super try.
Rhona Lloyd try, Helen Nelson con
Evie Gallagher wins a turnover and Scotland are clinical with the quick ball.
Emma Orr fends off Nel Matcalfe to release Lloyd and the sevens flyer is clear - and even hurdles the desperate flying tackle of Jazz Joyce her GB teammate.
Nelson has really got her kicking boots on, another wonderful conversion from the touchline.

Wales 6-10 Scotland
Scotland were out-muscled by Wales last year but there's absolutely no sign of that here today.
Even scrum-half Mattinson is weighing in, snagging Wales number eight Bethan Lewis early to prevent any attack.

Elinor Snowsill
Former Wales fly-half on BBC Radio Wales
It's a real fine line between being really brave and going for the five metres out to give your forward the best chance to drive over but it's also weighing up the momentum of the game.
How many times have you managed to go into the opposition 22 in the last five minutes and do you need to go for a safer kick?
Wales 6-10 Scotland
Scotland have never won in Cardiff... just saying.
Wales 6-10 Scotland
Well Caryl, she just tried to with a cross-field kick but she's also having to manage the wind and puts one straight out into touch.

Caryl James
Former Wales wing on BBC Radio Cymru
The Scottish backs are shining and they're looking like a dangerous team.
Wales can have success in the set plays and if Lleucu George can play in the correct areas of the pitch, we can enjoy a lot of variation.

That's the sort of immediate impact you want from a replacement as Georgia Evans stops the Scottish lineout and wins the turnover.
Evans will be out to prove a point after missing out on a start.
