Alun Wyn Jones hits a hole in midfield and hands on to Dan Biggar who runs in from 30 metres to give the Ospreys a dream start to the second half. The conversion is a formality.

And after not giving away a penalty within kicking distance in the first half Blues' Sam Warburton is pinged at a ruck, but Dan Biggar misses the target.

Glasgow's 31-13 win at Connacht is bad news for the Ospreys too. It lifts Glasgow to the top of the Pro12 table and makes it tougher for the Welsh region to finish in the top two.

But the Ospreys have to win this game first, of course.

Whether you're a Blues, Ospreys, Dragons or Scarlets fan - what do you think of Judgement Day III so far?

Ah, here they are. Perhaps they had a bit of a dressing down at the interval!

The teams are back out for the second half. Wee the Cardiff Blues are anyway, there's no sign of the Ospreys.

"There were a lot of mistakes out there in the early stages but the teams got better as the half went on.

"In the front row it's nice to see Nicky Smith back, the two hookers are matching up well, the two sevens - Justin Tuipuric is having a good game.

"I've been really impressed with Rhys Patchell in attack in the first half."

Nice beard, by the way, Mr Gatland!

"It was a fantastic opening 20 minutes of discipline and control from the Blues.

"We talk about set-piece control, well the Blues were dominant in the scrum as well as the line out, with Alun Wyn Jones caught out twice.

"Tommy Isaacs was really aware of what Ospreys were trying to do and made some great stops.

"Great work from the Blues, now they just need more of the same."

Look at those penalty statistics. That's great discipline by the Blues.

"What a great try from Dan Evans.

"He just brushed Joaquin Tuculet out the way, and what a breath that will be for all those wondering who the next Gethin Jenkins will be.

"Lots of praise to Dan Biggar, but it's always the way isn't it, the full-backs taking all the glory after someone else's hard work!"

Well that was not in the script. Blues have played really well and taken advantage of Ospreys errors, which have not been rare.

Their discipline was key as well, with Ospreys not having a single kick at goal apart from Biggar's conversion of Evans' try.

The Blues will be disappointed not to be further ahead.

Dan Biggar gets an accidental boot in the face from his Wales captain Sam Warburton who apologises quickly. THey are the best of friends really - even when they are playing for opposing teams.

Dan Evans crosses after outstanding work by Dan Biggar up the middle. Biggar converts brilliantly from the touchline.

Blues captain Gethin Jenkins returns to the fray after having running repairs to his fingers.

The Blues blow a golden chance as Rhys Patchell makes good ground but Tom Isaac and Joaquin Tuculet make a hash of things with the line at their mercy.

"Warburton appears to have taken over as skipper in Jenkins' absence, he was the one that pointed to the posts for the penalty.

"It's a great kick there, you wouldn't expect Anscombe to miss that one, and rightly so. Blues are leading 9-0 here."

Cardiff Blues' bright start has perked up their large contingent of fans, who might not have been brimming with confidence ahead of this match.

A crowd of what appears to be at least 50,000 is significantly bigger - and louder - than those the two previous Judgement Days have attracted.

And if the Blues can keep this up against the play-off chasing Ospreys, expect the Millennium Stadium roof to start wobbling.

More Blues pressure yields a third penalty for Gareth Anscombe. This is not what the experts were predicting.

Gethin Jenkins is off the field with a hand injury, so Sam Hobbs comes on as a temporary sub.

Garyn Smith is bundled into touch a yard short by Dan Biggar as the Blues go close to scoring the opening try of the game. You can't take your eyes off it.
