Here goes Thomas Young. It's breathless stuff.

Yes, Cameron Anderson would have been fuming if that try wasn't given because he was completely unmarked for a walk-in.

What a fantastic game we have here but Cardiff can feel aggrieved, I don't think he got it down.
Bit of white line fever from Oscar Beard it was a bit of greedy from him.
Oscar Beard try, Marcus Smith con
Well he's given it.
It looked like Mason Grady had pulled off an amazing tackle to deny the Quins centre but referee Frank Murphy says he got it down.
I have to say, that was a VERY marginal call.

Mason Grady with a massive last ditch tackle there.
I think Oscar Beard has lost it, that for Harlequins will be really painful, with a man outside that was a walk in!
Cardiff 15-21 Harlequins
Well what did I say, has Oscar Beard touched down?
Mason Grady got across with the last-ditch tackle.
This is a big call. If Quins have got a fourth, that's a bonus and at least a 11-point lead.

Two minutes remaining but the way this game is going, you wouldn't bet against another try.

It all began with Nick David the Harlequins winger picks out Willis Halaholo, steps him and is through.
Tinus de Beer makes another last ditch tackle but Danny Care puts the ball in behind Cardiff and it was only a matter of time before Harlequins scored.
Will Evans try, Marcus Smith con
Quins take the lead for the first time.
It all started from Tyrone Green winning the aerial battle for a high kick.
Will Collier went close, the forward took turns to have a go. Cardiff's goal-line defence was actually pretty good but it was relentless.
Cardiff 15-14 Harlequins
I've got to say, it's a fascinating duel between the two number nines Danny Care and Tomos Williams.
Cardiff will REALLY miss the Wales scrum-half when he joins Gloucester next season.
He has been the beating heart of the team this season.

What a game we have here tonight!
Marcus Smith and Danny Care interlinking but what I like about this is the speed of ball.
Cardiff 15-14 Harlequins
Oh what a passage of play. Cardiff putting Quins under all sorts of pressure, the ball is bobbling around but Marcus Smith launches an attack from behind his own posts!
Smith races past three players, Will Evans is on hand but then kicks the ball up field and Tomos Williams recovers.
That could have been try of the season!
Andre Esterhuizen try, Marcus Smith con
Well they were just stopped short but that didn't dent Harlequins' ambition.
Danny Care pulling the strings and centre Esterhuizen rumbles down the left wing to score their second.
Cardiff 15-7 Harlequins
Oh Quins looked odds on to score there from the driving lineout but Jack Walker is held up over the line by Tinus De Beer.
What a save from the fly-half.
Cardiff 15-7 Harlequins
Again Cardiff concede a penalty from the re-start.
It's a real Achilles heel.
Thomas Young try, Tinus De Beer con
He's got a second!
That was all about pace and handling skills. Harry Millard streaks down the right wing, Tomos Williams provides the link and Young - like all good opensides - is on hand to finish from a couple of yards out.
Cardiff 8-7 Harlequins
Fair play this is cracking stuff from both teams on this fast surface.
You attack and we'll attack and let's see who scores the most!

Warren Gatland names his squad on Tuesday but will have to deal with the fallout from this weekend.
Ospreys hooker Dewi Lake suffered a hamstring injury last night against Perpignan.
And Josh Maclead hobbled out of Scarlets loss at Clermont earlier today.
Johnny Williams was sent off in that game so is facing a ban and fly-half Sam Costelow suffered a head injury.
It never rain but pours...
Cardiff 8-7 Harlequins
Cardiff full-back Cam Winnett is off for a head injury assessment.
Ben Thomas is on but that's a blow for Cardiff.
Winnett has been one of their stand-out players so far this season and is being tipped for a place in Warren Gatland's Six Nations squad.

That's a very good turnover from Tinus de Beer especially from a 10 saving the day for Cardiff.
Harlequins are coming into it, doing their patterns and it's all very slick out the back and little touches.
