Great work from Scotland captain Jamie Ritchie as he spots a gap, leans in and steals the ball away from a cluster of red shirts.

Stuart Hogg won't be coming back on after failing his HIA... Blair Kinghorn will have a longer run at full-back than he expected.

Dan Biggar bangs it wide from a central position. A fair way out, but you'd expect him to make that every time.

Scotland are penalised from the scrum again and Dan Biggar will go for the posts.

The competition in the tackle is fierce. Both sides really fancy it.

Wales struggled in the set-piece last week against Ireland and that has continued this weekend with two early lost lineouts.

Captain Ken Owen's first throw was not straight and then they lost another five metres from Scotland's line. They can't afford to keep doing this.

Wales are still knocking at the door, with a scrum within striking distance.

Hang on, they're pinged for offside from the set-piece.

More groans from the visiting support.

How many times did we say this last week?

Every time they were in the 22-yard line they didn't score.

They have to sort out this lineout. It's only six points but Wales need a score.

Scotland repel the lineout impressively, with Richie Gray ripping the ball away. That's cheered like a try by the home crowd.

Penalty for Wales as Finn Russell is gobbled up deep in his own 22. It's kicked into touch.

Lovely timing from Finn Russell as he sends the ball sailing between the posts.

Wales fly-half Dan Biggar was in combative mood before the game in his pre-match press conference.

On the field, he has just given young wing Rio Dyer a stern telling off for a poor pass which put the visitors under pressure and ultimately led to Scotland's second penalty.

Bit of panic there from Rio Dyer. He just chucked it back to Biggar who was expecting Rio to kick.

That's put Wales under real pressure.

Scotland make up ground with a good kick-chase, with four players in blue napping at the heels of Rio Dyer.

Scotland full-back Stuart Hogg has to sprint down the tunnel for some attention as blood leaks from his mouth.

Blair Kinghorn is his replacement.

Richie Gray is having a real renaissance in his career... Graynaissance as it's known in these parts.

He's one of the best athletes I ever played with. He would set amateur rowing records in his time off rugby.

It's great to see him back at this level having been a British and Irish Lion back in 2013.

Now Ben White is steaming forward for the home side after a great steal from Pierre Schoeman. A Welsh hand stops the scrum-half from popping off a pass.

Finn Russell pops over an easy one for the first points of the game.

It's the eyes from Tuipulotu that do Wales.

Superb attacking play from Scotland early on.

Huw Jones breaks into clear open water from a delayed pass by Sione Tuipulotu after a rumbling maul from the Scots.

It's a great break that has Wales scrambling but they hang on, while conceding a penalty for offside.
