Wales secure their eighth win in a row & chase Autumn clean sweep
Steve Mafi (39 mins)
Tonga camped a metre or so from the Welsh line, but there's a huddle of bodies between them and a second try.
Wales hold firm as the bruisers in red continue to roll out the back of the ruck and look for an opening.
And they find one! Great pick and go from Steve Mafi, the subtlest hint of a dummy and he crashes over from close range.
Game on.

Vunga Lilo looks to float through a gap in the Welsh defence but is well wrapped up.
Tonga come again, they've got a bit of momentum behind them now and Wales' in-discipline is giving the visitors chances to make ground.
Another penalty, and Kurt Morath sticks it deep into touch.

After Wales storming start things have just gone a bit flat at the Principality Stadium with Tonga enjoying a period of domination.
Wales will need to wrestle back the initiative just before half-time.

Five minutes until the break. Wales started superbly with Tonga down to 14 men, but it's the Pacific Islanders who are finishing the stronger.

Tom Williams does brilliantly there to try and block the touchdown with his head. If only his head was a bigger size. If his head was as big at Richie Rees' that would not have been a try!
Leva Fifita (32 mins)
So the ball does appear to have touched the pad. The on-field decision was 'no try', but it's overturned - try Tonga! Leva Fifita is the man to have rammed it against the post.
Over go the extras. Wales not quite so comfortable anymore...

Sione Vailanu thinks he's down, not quite, but Tonga have a penalty coming... now Leva Fifita reckons he's grounded against the post.
Off to the TMO...
Wales 24-3 Tonga
Head back, arms pumping, away goes Sione Vailanu until he crashes into a dark blue defender - are those shirts dark blue or black? My screen-weary eyes can't tell.
Good spell of pressure for the Tongans. Another scrum five metres from home.

You just feel Tonga need to get something now. They've had a good ten minutes, have applied lots of pressure, but they still have nothing to show for it.

Sam Warburton

Wales are looking to be nice and solid at the scrum. Tonga probably feel they can take a few more risks now.
Wales 24-3 Tonga
Just settling down a little bit this game after a blistering start - we've not had a point for a whole seven minutes.
Here come Tonga, working phase after phase to try and engineer numbers on the left.
Martyn Williams
Former Wales international in the BBC studio
You are always worried before these tricky games, but Wales banished any fears with that electric start. Their attacking play has been so accurate and I've been really impressed. On the other hand, Tonga's discipline is really letting them down.

Tonga are not getting enough of the ball and when they are they are making mistakes, especially at the line-out.
Wales 24-3 Tonga
Tonga think they've executed a nice line-out five metres from the dancefloor, but the throw's not straight and there's exasperation on the face of the visitors' pack.
Good chance wasted.

Tonga need to keep possession and try and settle things down. They are doing things the hard way, going for double top every time.

Seb Davies knocks on. A finger-tipper. That gives Tonga the put-in 10 metres inside the Wales half.
They hit the blindside, but that pass from Siale Piutau is well forward.

Tonga captain Siale Piutau has spent the first quarter remonstrating with Australian referee Nic Berry about a series of decisions he feels have gone against the visitors ranging from yellow cards to a disallowed try. Wales are just going about their business.
Dan Biggar (21 mins)
No mistake from Dan Biggar. He sticks another three on the board as the Welsh lead increases.

Adam Wainwright will be feeling the effects of that one, he just got absolutely smashed!
