Scotland ended 22 years of hurt in Cardiff after they thwarted a spectacular Wales fightback to win an extraordinary Guinness Six Nations clash 27-26.

It was Scotland’s first win in the Welsh capital since 2002 – ending a run of 11 successive defeats – to set up a mouth-watering Murrayfield encounter against France next Saturday.

But Wales made them fight every inch of the way after the Scots had breezed into a 27-point lead after 42 minutes, with wing Duhan van der Merwe scoring two tries including a virtuoso long-range effort while prop Pierre Schoeman also touched down.

Captain Finn Russell kicked three conversions and two penalties, but it only told half the story.

Flanker James Botham’s try sparked the Welsh recovery then he was followed over the line by Rio Dyer, Aaron Wainwright and debutant Alex Mann, with Ioan Lloyd kicking three conversions.

Scotland found themselves on the rack after hooker George Turner and centre Sione Tuipulotu were sin-binned during the second period, yet they successfully closed the game out and left Wales wondering what might have been.

Both teams started brightly under the stadium’s closed roof and Scotland struck first when Russell kicked an angled 20-metre penalty, before quick lineout ball gave Tuipulotu a chance that Wales managed to defend.

Wales, though, could not stop wave after wave of attacks that led to the game’s opening try after 11 minutes.

Russell created initial space and after a strong run by wing Kyle Steyn, Scotland’s forwards took over and Schoeman crossed from close range. Russell’s conversion made it 10-0.

Scotland enjoyed scrum and lineout dominance and they controlled the opening quarter, even if Wales established promising attacking positions at times.

Russell extended Scotland’s lead with a second penalty – Wales wing Josh Adams was punished for throwing the ball away and denying Scotland a quick lineout throw – and alarm bells were beginning to ring for Gatland’s team.

Inevitably, Russell was at the heart of everything good about Scotland’s magic and he weaved his magic to devastating effect 10 minutes before half-time.

Scotland set up a strong position inside Wales’ 22 and the rest was all about Russell, who ghosted into space, threw a half-dummy pass, then delivered a try on a plate for Van der Merwe.

There appeared no way back for Wales, with their problems showing no sign of abating as fly-half Sam Costelow went off for a head injury assessment as Scotland led 20-0 at the interval.

It got even worse for Wales just two minutes into the second period when Van der Merwe carved them open from deep to claim a blistering solo touchdown, and Russell’s conversion put further daylight between the teams.

Costelow failed his HIA and Gatland made three half-time changes, sending on scrum-half Tomos Williams, hooker Elliot Dee and prop Keiron Assiratti, and Wales opened their account when Botham crashed over.

Turner was sin-binned for an offence in the build-up to Botham’s try and Wales struck again, this time through Dyer, with Lloyd’s conversion cutting the gap suddenly and unexpectedly to 15 points.

It was panic stations for Scotland when Tuipulotu went into the sin bin and Wales punished them immediately as Wainwright touched down for a third try in 13 minutes, with Lloyd converting.

The capacity crowd could scarcely believe what they were witnessing, but it was Williams’s influence off the bench that proved key as he injected pace and purpose into Wales’ game.

And when Mann claimed a 68th-minute try, again converted by Lloyd, the improbable dream edged closer, with Scotland looking bewildered and devoid of answers.

But they somehow held out, Wales left with the consolation of two losing bonus points.

Aaron Wainwright has handed Welsh rugby a major pre-Six Nations boost by agreeing a new contract with the Dragons.

The Wales back-row forward, who looks set to line up at number eight in next week’s Six Nations clash against Scotland, has agreed what the Dragons described as “a multi-year” deal.

The 26-year-old would undoubtedly have courted considerable interest elsewhere, given his Test experience of 43 caps and outstanding displays during the Rugby World Cup in France.

“Lots of positive conversations have gone on between Dai (Dragons head coach Dai Flanagan), myself and the club,” Wainwright said.

“I am looking forward to the next few years. I love the Dragons, I am a home boy.

“I love turning up to Rodney Parade, seeing fans out on the terraces, and that’s what I want to keep doing, turning up on a Friday, Saturday or Sunday and playing well, trying to make them happy.

“I am happy to have re-signed and I am excited to see what the next few years have to hold.”

Wainwright made his Wales debut in 2018 and he has developed into a player whose consistency of performance is an invaluable commodity for head coach Warren Gatland.

Only six players – and just two forwards – have more caps than him in Wales’ 34-strong Six Nations squad, and he is comfortably the senior back-row figure.

With Taulupe Faletau sidelined for the whole Six Nations, along with flanker and co-captain Jac Morgan, through injury, Wainwright will head up Gatland’s back-row resources.

A move from blindside flanker can be expected, unless Gatland hands uncapped Cardiff number eight Mackenzie Martin an opportunity and leaves Wainwright in the number six shirt.

“It is a fairly young group at the moment. It is definitely exciting, and it is about how we build on that,” Wainwright added.

“When I came in for my first campaign, some of the back rows in the squad – Tips (Justin Tipuric), Lyds (Dan Lydiate), Taulupe (Faletau) – it’s trying to be a figure to them like those boys were to me. I am just trying to be the best role model for them.

“I am not always the loudest of talkers. I hope to do it through my actions.

“We have been pushing each other in training, and everyone has fitted in well really quickly. We’ve only had three days of training, but information is being taken on really quickly.”

Scotland have not beaten Wales in Cardiff since 2002 – current head coach Gregor Townsend was their fly-half that day – losing 11 successive Tests in the Welsh capital.

But they have been strongly backed to end that sequence, particularly given Wales’ inexperience and the absence of players like Faletau, Morgan, Louis Rees-Zammit, Liam Williams and Dan Biggar.

The squad’s cap total is 735, but 438 of those appearances have been made by just seven players – Wainwright, Josh Adams, George North, Gareth Davies, Tomos Williams, Elliot Dee and Adam Beard.

Aaron Wainwright admits Wales will face a team that sets the bar in terms of physicality when they meet World Cup warm-up opponents South Africa on Saturday.

Wales’ final preparation Test promises to be a full-on spectacle at the Principality Stadium, with reigning world champions South Africa parading many of their star names.

Fit-again captain Siya Kolisi returns to the starting line-up after recovering from a serious knee injury, while 390 caps worth of experience up front also includes players such as Steven Kitshoff, Malcolm Marx and Pieter-Steph du Toit.

“We have spoken about physicality all week,” Wales number eight Wainwright said.

“If there is a team you are going to come up against at international level that is going to set the bar physicality-wise it is going to be South Africa.

“We have spoken about what we can bring to them in the physical test.

“Let’s not wait for them to bring the challenge to us. Let’s get off the line and meet them and show what we can do physically.

“I think the past two games we have played against England we have set our mark physicality-wise and it’s about building on that now, taking it into Saturday and then the World Cup.

“It is going to be a big test for us, but we have spoken about that and we know that is coming.”

Wainwright looks like being a key part of Wales’ back-row armoury at the World Cup.

He made his Test debut in 2018 and featured during the following year’s global showpiece tournament in Japan, but he has also experienced time in the wilderness, not being involved for 14 successive Tests before Wales faced France in last season’s Six Nations.

“Going to Japan quite young and experiencing that World Cup, I look back with fond memories, but I probably did not capture it as well as I would have liked to,” he added.

“The training camps I have gone on this time in Switzerland and Turkey I have been able to experience things a lot more, enjoy working hard and being around the boys.

“I played the final game of the Six Nations and loved my opportunity to get back on the pitch and put the red jersey on again.

“You can see the depth we are developing across the back row. Taulupe (Faletau) is out for now, but he is pretty close to returning, which is great for the team and for him.

“For me, it is another chance to put my hand up on the weekend and show what I can do.

“I enjoy my rugby more when I get my hands on the ball and carry. If I can keep doing that, I can keep putting my hands up.”

Wales head coach Warren Gatland’s final 33-strong World Cup squad will be announced on Monday, but a formidable Springboks challenge means that minds cannot be allowed to wander.

“It is going to be in the back of people’s minds, naturally, because it is a World Cup selection,” Wainwright said.

“But is about getting on the pitch and playing as well as you can and letting the rest take care of itself.”
