Scotland 24-25 Wales
Scotland batter away but can't make much ground. Finn Russell grubbers through, and Wales slow it down before kicking the ball back to Scotland.
Wales defending for their lives. Bodies everywhere.
Scotland 24-25 Wales
Great turnover from Justin Tipuric after a really good defensive set.
It's absolutely breathless, as Callum Sheedy gives us all a break by calling a mark.

Quote MessageWhat a brilliant try. There's not too many people who can outpace Stuart Hogg. Rees-Zammit has pace to burn and what a great finish.

Louis Rees-Zammit must think international rugby is easy!
What a brilliant player, and what a brilliant try. Amazing!
Louis Rees-Zammit
A blockbuster score from a phenomenal young talent!
Wales know they have the edge on the outside and are getting width on the ball at any opportunity.
Rees-Zammit receives on the right touchline, kicks over and uses his searing pace to beat everyone to the ball and score. Incredible gas.
Callum Sheedy misses the extras again. A bonus-point score for Wales though!
Scotland 24-20 Wales
Ooft, so close to a Wales try!
A lovely kick through from Callum Sheedy bounces in goal, and Stuart Hogg just manages to beat Louis Rees-Zammit to the ball to prevent a score.
A rollercoaster ride, this one. Oli Kebble and Dave Cherry on for Scotland in the front row.

Quote MessageBrilliant finish by Stuart Hogg. I thought that was just enough to hold him but, but what a finish!

It was just a simple hand-off from Stuart Hogg that allowed him to brush Owen Watkin aside.
That try was far too easy for Scotland.
Stuart Hogg
What a Test match!
Scotland hold the scrum after a few resets, spin it to Hogg who holds off Owen Watkin to wrestle over.
Finn Russell nails the conversion from the touchline. What a response from Scotland.
A long, long way to go, though.

Ross Matthewman: Quite a terrible day for DRS in India, and now TMO in the rugby. Never ever a red card. VAR must be delighted to see their friends getting it so wrong as well.
Scotland 17-20 Wales
Yet another Scotland penalty at the scrum. We must be entering yellow card territory. That's certainly Scotland's hope anyway.
They go for another crack at the scrum. Leon Brown replaces Tomas Francis in the Welsh front row. James Botham on for Aaron Wainwright in the back-row.
Scotland 17-20 Wales
Another penalty Scotland, right in front of the sticks. Wales captain Alun Wyn Jones has been pinged.
They've elected to scrum. Very bold.
Richie Gray has replaced Darcy Graham, by the way. Scotland keeping it eight a-side in the forwards.
Scotland 17-20 Wales
Bold from Scotland to go to the corner here when they got a kickable penalty from a scrum.
They're about 7m from the Welsh line...
Wyn Jones
What a turnaround!!
Wyn Jones barges over from close range and Wales are the ones in control.
That red card has been huge. Callum Sheedy can't convert.
Scotland 17-8 Wales
Have Wales barged their way over?! On field decision is TRY.

Quote MessageThat is an absolutely huge call from the referee, the TMO was trying to push him down the yellow card route and I think it's harsh.

Quote MessageThere's too many different things going on in there. You cannot definitively give that as a red card. I personally think there's too much mitigation and it should be a yellow card.
Scotland 17-15 Wales
A huge moment.
Zander Fagerson has come in from a distance to clear out Wyn Jones, who was trying to win the ball, and makes contact with the Wales prop's head.
It's not as clear cut as Peter O'Mahony's last week. There will be a lot of debate around it.
Scotland 17-15 Wales
The TMO is having a look for some foul play by Scotland prop Zander Fagerson.

That try demonstrated the importance of a strong line-out and maul.
Hopefully that try will spark a Welsh revival.
