Cardiff 15-26 Ospreys
Cardiff aren't going to take this lying down.

They will come again.

I think it's important now for the Ospreys to have a spell in possession, they use the phases and breakdowns well, I just want to see a bit more in the transition.
That's a great gain from the Ospreys, Dan Edwards did brilliantly there to get away.

Clinical from the Ospreys, lovely play sneaking around the back.
It was fast, it was urgent, it meant that that Cardiff got caught far too compact.
Dan Edwards has been fantastic today, another great pass.
Cardiff 15-26 Ospreys
Ospreys have their bonus-point try, they now have 15 minutes to hold onto the lead and they are in the play-offs.
Who'd have thought this at the start of the day?
Luke Morgan, con Dan Edwards
Morgan Morris picks up off the back of the scrum and a long pass from Dan Edwards puts Luke Morgan in at the corner.
Cardiff 15-19 Ospreys
Ospreys blew their first attempt at a five metre scrum, but they'll have another crack at it as they come back for the penalty.
Ben Thomas has been told to have a word with his Cardiff forwards, the next infringement will likely be a card.
Cardiff 15-19 Ospreys
Ben Donnell is back on, Cardiff have managed that yellow card very well.
Ben Thomas
It's another Cardiff penalty on the Ospreys 10 metre line.
Ben Thomas has the distance, but not the direction.
He used every second of the shot clock there.

Cameron Winnett is such a busy player, he's so happy to step in as a first receiver.
It was his inside line then which he ran to give Cardiff that burst, he's so important to this Cardiff team.
Cardiff 15-19 Ospreys
Cameron Winnett has had a great game, he's been pulling the strings from full-back.
But he's been limping around in the past few minutes, Warren Gatland must be having kittens!
Hopefully he'll run it off.
Ben Thomas
Cardiff have a chance to reduce the deficit to just three points.
Ben Thomas curls it in from the right-hand side.
Cardiff 12-19 Ospreys

Great from the Ospreys just grinding out the phases, the pressure finally paid.
This next 10 minutes is critical for the Ospreys, Ben Donnell in the bin, it's exciting.
Cardiff 12-19 Ospreys
A further blow for Cardiff as Ben Donnell is shown a yellow card in the build-up play for a professional foul.
Can Ospreys capitalise on the extra man?
Nicky Smith, con Dan Edwards
Ospreys aren't fussed about the sentiments of departing players - they have the play-offs to chase.
Nicky Smith is over for his second of the night.
Cardiff 12-12 Ospreys
A warm applause also for Rhys Carre who signs off his Cardiff career.
He's off to Saracens this summer.
Cardiff 12-12 Ospreys
Willis Halaholo is on for his final Cardiff appearance.
A great servant and a fan favourite.

Superb turnover there from James Botham, he got in there early and stopped the Ospreys 10 metres out from the Cardiff try line.
That could be an important moment come full time.
Cardiff 12-12 Ospreys
Ospreys get their chance, but Reuben Morgan Williams is isolated and it's a superb turnover from James Botham 10 metres from his own line.

Sean Holley

I think the Ospreys will get to four tries, the main question is how many will Cardiff score.
This next 20 minutes is so important, the Ospreys need to create some separation between themselves and Cardiff.
Cardiff 12-12 Ospreys
Cardiff looking the most threatening in these early stages of the second half.
They're looking to play the ball from everywhere!
