Wow, a third scrum and third penalty for Wales.

Thomas Clarkson is getting a tough time from Nicky Smith on his Test debut.

He needs to be careful he doesn't get a card here.

Ireland are running through the phases here and are looking pretty comfortable.

James Lowe almost finds half a gap but Ellis Mee just does enough.

Wales are being pinned back.

Wales have played far more creatively than we've seen in the first two games.

That's what happens when you've got a fly-half playing at fly-half. Wales are being patient and they're keeping their sense, but they need to be able to recycle these phases.

Ireland make a mess of a long lineout throw that was intended for Robbie Henshaw.

But from the resulting scrum, they have conceded a second penalty.

Ireland not getting the best from their set-piece.

You're seeing an energy to Wales' attack.

They probably look better than they have done in the opening two games.

Daf Jenkins and Elliot Dee are penalised for a tip tackle on Tadhg Beirne and Ireland are able to kick themselves up field.

That was needless from Wales.

An early blow for Wales.

What will that do to their already-shattered confidence?

Taulupe Faletau has a crack to try and lift spirits.

Max Llewellyn has already had a few carries.

John Barclay
Former Scotland captain on BBC One

The try comes from an exceptional carry from Joe McCarthy. Wales haven't done a lot wrong but that's why Ireland are so good.

Just relentlessness and ruthless efficiency to everything they do.

Jonathan Davies
Former Wales international on BBC One

It just shows the difference, Ireland's speed of the ruck play is phenomenal.

It's so difficult to get back onside.

How exciting is this? The two scrum-halves today, Jamison Gibson-Park and Tomos Williams, along with Antoine Dupont are in the top three nines in the world.

These two have got to be the front runners for going on that British and Irish Lions tour in the summer.

What an opportunity for these two to challenge each other on the biggest stage.

Gary Ringrose puts in a wonderful 50-22 and Ireland are back up field.

Early chance for the visitors.

Jonathan Davies
Former Wales international on BBC One

Wales have done quite well in the set piece, the scrums and lineouts went well.

You have to get the basics right just to get any level of competition.

Two new front-rows go head to head and Wales get the penalty.

That's about the only area that has done well so far this Six Nations for Wales.

Sam Prendergast sends up a high one and Wales full-back Blair Murray fumbles so it's a scrum just inside the Welsh half.

Sam Warburton
Former Wales captain on BBC One

Wales have got to make Ireland uncomfortable from minute one.

You have to be aggressive and relentless and put them under pressure immediately and let them know they're playing in Cardiff.

English referee Christophe Ridley blows his whistle and Sam Predergast gets us under way here inside the Principality Stadium.

Ireland second row Tadhg Beirne, speaking on BBC One:

"[The focus] has been on ourselves. This group wants to continue to get better. There's been a focus on Wales and what they're going to bring as well.

"We haven't had the best success here over the years so we want to put that right today."

On what Wales will bring...

"A lot of passion, we don't really know. They'll change their system up a bit no doubt. They've got nothing to lose today They can go out and express themselves."

Seven changes for Ireland...

"With the way we've trained over the past two weeks, it's looked fairly good and we'll hopefully show that on the field today."

I asked you earlier how many Triple Crowns have previously been won by Ireland.

The answer was B) 13.

Get it right?
