Wales are looking the more likely, running harder and looking fitter.

But that is great work from Jared Payne and Andrew Trimble tag-teaming up on Liam Williams to keep the Wales full-back off the floor and secure the turnover.

Heading for a draw...

"Both sets of players were out on their feet at the end. Wales had a real chance then to win the game.

"If they had kept their shape you could have seen Ireland give away a penalty."

Rhys Priestland back into the pocket... here we go.

Nope. A scuffed effort hooks well wide.

A shake of the head from the replacement fly-half. Perhaps a little premature. Wales could have got a little closer in to make the kick easier for him.

Wales have Ireland penned back deep in their own territory.

Johnny Sexton won't be the matchwinner. He is off and Ian Madigan is on in his place at fly-half for Ireland.

"Before the game there were not many realistic Irish fans confident of winning.

"But they have been the better side for long periods and will be disappointed if they don't get a result here."

Tightrope rugby.

Johnny Sexton wills the ball over the crossbar and his kick has just enough umph to make it.

Scores level. The next points are the killer.

A chance for Ireland to bite straight back as Wales focus wavers and they give away a basic penalty.

"Superb defence from Ireland but they will be raging that they were not able to see it out."

Eight minutes to go and Wales are ahead for the first time in the match.

Priestland's kick is unerring and his team are within sniffing distance. 

Ireland's defence prevails - but then their concentration lets them down straight away.

Jamie Heaslip pilfers the ball to wild cheers. But his exhausted team-mates relax too early and Sam Warburton comes through the middle of half-heated ruck.

Ireland hanging on and that is penalty Wales!

This is bruising.

Proper trench warfare as Welsh runners crash into Ireland defenders again and again.

Twenty-five phases now...

Wales working through the phases.

Fifteen on the clock so far and they are into the Ireland 22 metre.

The ball is slow though and Ireland are well set.

"Wales are frustrating Ireland defensively and a few mistakes are creeping in from Ireland."

Mike McCarthy is off and Donnacha Ryan slots into the Ireland second row.

Ken Owens is on at hooker for Wales with Scott Baldwin making way.

Johnny Sexton like a rat up a drain pipe - disappearing down a gap inside Jonathan Davies and scampering downfield!

Aviva on its feet, Andrew Trimble screaming up on his outside shoulder.

Sexton's pass finds Trimble - but so does Tom James with a terrific covering tackle.

Try-saver.

"I always think Ireland play a large amount of rugby between the 15 and the 22. It's to bring up the full-back but it's such a high-risk strategy and Ireland are just about getting away with it."

Bradley Davies comes on to replace Luke Charteris in the Wales second row.

There are more changes coming as well.
