We're seeing some replays of the Adams try that show it should not have stood.
Jonathan Davies' pass to the winger was forward.
It was a fantastic dancing finish from Adams but the Scots will be pretty angry that hasn't been spotted.
Have a look for yourselves...

Quote MessageScotland will be disappointed with the scores they conceded, especially as they looked dangerous when they got into the Welsh 22.

Quote MessageWarren Gatland will be very happy that. Pretty much every time Wales have got into the Scottish half, they have come away with something.
Scotland escape as Gareth Davies knocks the ball forward from that scrum. Wales are in command at the break, though - they've been very impressive.
Tries from Josh Adams and Jonathan Davies and a Gareth Anscombe penalty have put the Grand Slam-chasers in pole position. Their play has been too powerful and too canny for Scotland to handle.
Gregor Townsend's men have had their moments in the Welsh 22 but they have only two Finn Russell penalties to show for their efforts.
They've also lost two backs to injury in Tommy Seymour and Blair Kinghorn and are now playing fly-half Adam Hastings at full-back. Expect the Welsh kickers to put him and fellow rookie Darcy Graham under plenty pressure with high balls in the second half.

Oh dear, Scotland make a mess of the line-out right on their own line and Ali Price gets swamped and marched back over his own line.
Scrum-five, Welsh put-in, big chance for a third try.

Woah, it's thumped back off the post. Wales regather and here they come again!
Chaos in the Scottish 22 as Wales chuck it wide and Adams scampers for the corner, but a gang of home defenders bundle him out at the corner.
Adam Hastings and Allan Dell were the tacklers and Hastings has taken a dunt...thankfully, mercifully for Scotland, he has not been forced off.

The line-out is scrappy as the tap-back flies behind Gareth Davies, but Wales stay calm and regroup and they win a penalty for Jamie Ritchie going too far beyond the ball as he tries to burgle it from a ruck.
It looks a pretty harsh call on the Scotland flanker but it's given Anscombe the chance to stretch the Welsh lead to 12.

Quote MessageWales are controlling the pace of the game and Scotland have to get up off the line quicker in defence.

This looks ominous for Scotland. They win a penalty and a brilliant Anscombe kick takes play up to within five metres of the Scottish try-line.
Big chance for Wales to go further ahead...
Scotland 6-15 Wales
Alun Wyn Jones is having a whale of a game. The wily Welsh captain has been everywhere in the opening half, making a few telling carries and delivering a couple of cracking little off-loads.
The big fella stoops brilliantly to pick an Anscombe off-load off his bootlaces and powers through the Scottish line again.
Wales have a tight grip on this game.

It has been a trait of Wales during the Six Nations that their attacking build-up has been methodical until they break down the opposition.
That was the perfect example and Jonathan Davies was the beneficiary.

Quote MessageWhat was very clever was they constantly kept the Scottish defence guessing, then there were fantastic skill-sets from Jonathan Davies stepping through.

Quote MessageSheer quality. Wales go through 23 phases and every man knew what he was doing. It's a great line by Hadleigh Parkes and it's a brilliantly worked try. That control is the difference between the two sides.
Scotland 6-15 Wales
Blair Kinghorn can't continue. This is an astonishing spate of first-half injuries.
Having already brought on Byron McGuigan for Tommy Seymour, Gregor Townsend has to introduce his back-up fly-half Adam Hastings to play full-back.
He's played a bit of rugby there but certainly not at this level...
Jonathan Davies
Ruthless. Utterly ruthless. This is the rugby of champions.
Wales are patient and powerful. They rack up well over 20 phases in the Scottish 22, everyone knows their jobs and executes them to perfection.
Hadleigh Parkes twice cuts searing out-to-in lines that puncture the Scottish fringe defence, before the ball is spread wide for Jonathan Davies to dummy and power over.
Gareth Anscombe can't quite convert but Wales are looking very good.
Scotland 6-10 Wales
After that Kinghorn knock-on, Wales win a penalty at the scrummage for a WP Nel binding infringement.
They kick down int o the Scottish 22 and assemble their bruisers for a raid on the try-line.

I can't remember seeing so many injuries so early in a Test match - even in today's ultra-brutal era of rugby.
Blair Kinghorn gets clattered and spills the ball forward as her arcs his way into the Scottish attacking line. He needs some treatment and looks less than comfortable hirpling back into position.
Scotland have used their back-three replacement in Byron McGuigan and could do without any further damage to personnel.
