Wales claimed the inaugural Doddie Weir Cup with a 21-10 win as Scotland's miserable run in Cardiff continued.

Wales have triumphed in the last 10 games against Scotland in Cardiff, a winning streak going back to 2002.

Tries from George North and Jonathan Davies were complemented by 11 points from the boot of Leigh Halfpenny.

Scotland responded with a try from captain Stuart McInally, but were left to rue poor midfield defence and discipline.

Centre Huw Jones was exposed as his two missed tackles cost Scotland tries as Wales won six successive games for the first time since 2012.

Warren Gatland's side have won 11 out of the last 12 matches against Scotland as Wales secured an opening autumn international victory for the first time in 16 years.

It was an ideal warm-up for Wales before their attempt to defeat Australia next Saturday after 13 successive losses against the Wallabies.

Scotland's poor away form continued as they struggled to break down Wales' dynamic defence typified by man-of-the-match Justin Tipuric and Dan Lydiate.

This was despite the home side being reduced to 14 men late on through Elliot Dee's yellow card.

Gregor Townsend's men will be on more familiar territory next week when they host Fiji at Murrayfield.

Doddie's Day

The fixture had raised eyebrows when it was announced because Wales usually play a southern hemisphere superpower for a fourth international that falls outside World Rugby's international window.

This was only the second time in 124 meetings Wales and Scotland have played each other outside of the Five or Six Nations.

The previous occasion was a World Cup warm-up in 2003 when Wales won a match that saved Steve Hansen's career there.

Wales and Scotland were competing for the Doddie Weir Cup with the former Scotland and Lions second-row suffering from motor neurone disease.

Controversy had developed after it was revealed originally none of the expected £3m gate receipts were going directly to the foundation.

The Welsh and Scottish Rugby Unions eventually announced they were donating a six-figure after bowing to public pressure.

That ensured the match was all about Weir and he received a warm ovation before kick-off when he brought the cup into the arena, accompanied by his family.

Tens in focus

Uncapped wing Luke Morgan making his Wales debut and the focus on the two 10s were some of the pre-match talking points.

Gareth Anscombe impressed for the hosts while Adam Hastings, son of Scotland great Gavin, was winning only his fourth cap.

It was an inauspicious start for the Scotland fly-half as he missed his first penalty kick to touch in the opening exchanges.

Wales opened the scoring in the fifth minute with a Halfpenny kick after hooker Ken Owens won the penalty at a ruck.

Halfpenny continued to mercilessly punish the visitors and Hastings replied after a scrum penalty.

North star

There was no stopping North as he powered over for a 34th Test that try took him to third in Wales all-time try scoring list above Ieuan Evans with Shane Williams (58) and Gareth Thomas (40) in his sights. Halfpenny missed the conversion.

Scotland responded quickly with a try for McInally from a driving maul, which Hastings converted as Wales led 14-10 at the interval.

The hosts struck with their first meaningful attack of the first-half as centre Davies marked his return after year out of international rugby through injury in style.

Architect Anscombe provided the creative spark with a delicate delayed pass, but it was left to Davies to dismissively swat hapless opposite number Jones aside to sprint away and Halfpenny converted.

Scotland rallied through inspirational flanker Hamish Watson, and continually tested Wales with their driving line-out, but were denied after lock Jonny Gray was penalised for a double movement while crossing the hosts' line.

More Scottish pressure resulted in Raynal handing replacement hooker Dee a yellow card before Scotland were again denied by the TMO after replacement Peter Horne failed to ground a chip kick, summing up Scotland's day.

Wales coach Warren Gatland said: "We were a bit rusty at times. For long periods of the game we were pretty comfortable without the ball and defended well.

"We scored some nice tries and will be better for that. Scotland put us under a lot of pressure."
