It's the forwards winning the collisions for Wales in Scotland's 22.

But despite Wales' strong attacking position, it's Scotland who come away with the penalty as Will Rowlands is off his feet.

Wales win a shortened line-out and Gareth Davies opts for the box-kick.

The hosts are immediately awarded a penalty as hooker Fraser Brown obstructs Liam Williams in the chase.

That's the first scrum where Wales have been in the ascendancy.

A tap on the head for Wyn Jones.

Scarlets prop Wyn Jones replaces Rhys Carre and wins a penalty with his first scrum.

It's a similar story to the first half so far - plenty of territory and possession for Scotland who fail to capitalise on opportunities.

Wales win the defensive scrum in their own 22 and Jonathan Davies clears it.

Adam Hastings slides through the Welsh defence and Scotland are looking lively but once again they are held up and concede a second maul turnover within two minutes.

That's 11 turnovers for Scotland so far.

That was a great maul from Scotland but they wait until referee Andrew Brace says 'use it' and they lose momentum by the time Ali Price gets it to Darcy Graham.

Fair play to the Welsh defence for the turnover.

Scotland looked to be gaining momentum with the driving maul but Wales absorb the attack and win a turnover.

Adam Hastings is receiving attention from the Scottish medical team on his shoulder after a tackle on Owen Watkin.

He stays on but Wales will surely be testing him soon.

There are questions over Dan Biggar's fitness as he's substituted after two minutes by Rhys Patchell.

Both sides have now lost their starting fly-half to injury.

Owen Watkin grubbers into touch and Scotland are under pressure in their own 22 with the line-out

Sublime take under the high-ball from Leigh Halfpenny and Wales are on the attack early in this second half.

For all the possession and territory that they've had, how dominant they've been, Scotland only got two penalties to show for it which isn't a lot.

It doesn't boost your confidence massively.

Dan Biggar gets us going for the second half.

I think Scotland will be a little bit disappointed but I think they'll be happy that they managed to claw those three points back.

Lots to talk about in that Welsh dressing room.

They've got to improve on quite a few factors of their play to come out and really give a good impression in this second half.

Scotland need more in attack from the guy in the 12 jersey, It can't all be about defence.

For years in the Six Nations Scotland have conceded too many points, but you can't overcompensate for that.

I think James Lang is a very negative selection, I'm not convinced.

I am struggling to recall when conditions have so much dictated a half of international rugby with the wind dominating proceedings.

If we were at the Principality Stadium, the roof would be on and it would not be an issue. But we are not.

Scotland have dominated territory and possession but somehow Wales lead by a point.

A Wales side who have been penalised at the breakdown but kept out the Scottish attack.
