Dan Biggar is a little optimistic with his diagonal kick looking for Liam Williams. Too cute.

But Wales claim it at the line-out and can counter now, Tomos Williams, to Biggar and then Williams again, before the red shirts scramble back.

The hosts bring in Steff Evans on the other flank, and keep it moving through hands, only for Wyn Jones to knock on.

It'll be brought back for a penalty - off-the-ball hit on Aaron Wainwright.

Burrowing through is the right word, he was like a caterpillar there.

But there is just a tiny knock-on, I think that is a little unlucky there, Dan Biggar has got away with one there, they had to give it a forensic examination.

Nope.

No luck for Tonga. There was a knock on somewhere beneath those bodies.

Welsh scrum five metres out it is.

Tonga gain some good ground for the first time in this Test, ruck after ruck drawing in Welsh defenders five metres from their own line.

Then they whip it right, with Alaska Taufa cutting inside and taking it at pace on a nice line. Siale Piutau picks up out the back of the ruck and dives in between a huddle of bodies to ground.

This is going to the TMO....

A fine start for Jonah Holmes, his handling has been good and it was a key contribution for the third try. Wales are rampant.

Well we wondered whether a much-changed Wales would make a slow start but there has been nothing of the kind. Three well-worked tries against a stunned Tongan side culminating in a brilliant finish by Liam Williams. Superb stuff.

But Dan Biggar sticks his crossfield kick straight into touch, first blemish on his card today.

The improvement in that area has been good for rugby and that is an exceptional bit of play. It is brilliant support play and beautiful give and take. A great try.

Well, Wales stick two early tries on the board but are pulled up for a bit of ill-discipline in their own half and that gives Sonatane Takulua a chance to get Tonga off the mark.

No mistake, splitting the sticks. Electric start at the Principality.

That was a fantastic tackle from Owen Watkin, you see him do that all the time for the Ospreys. It is such an easy way to turnover possession

Richie Rees

It is another bright bit of play from Adam Wainwright, but it all comes from that turnover. What a start for Wales, they are so full of confidence.

And among all that there was a sin-bin for Tonga's Leva Fifita... the Pacific Islanders are a man, and seven points, down.

A really good trundle from Wales and a great start for them, but I feel for Seb Davies because that looked like it was going to be his try.

Wales get an early penalty and stick it deep into touch to tee up a line-out. Catch and drive. Good early pressure from the hosts.

The 'Sipi Tau' was well greeted at the Principality Stadium. Silence when the Tongans were laying down the challenge to the Wales and applause when they had finished. Samoa in red which is strange. Here we go.

Here we go.

Dan Biggar gets this one under way...
