Could be the Quins bonus-point try here....

Missed chance for Quins to get their fourth try perhaps as Danny Care's kick over the top runs a bit too long and into the Saracens in-goal area.

The visitors can clear upfield and reset.

Early mark taken by Alex Lewington in the Saracens 22 as Marcus Smith tries to exploit some space in their back field.

We might see a bit more of that if this weather continues.

Here we go again!

Here comes Saracens out of the tunnel ready for the second half.

That's interrupted the latest batch of Ibiza club classics on the PA here sadly.

Have to head off to the bright lights of the West End for more later perhaps.

Quins back out as well now as the rain continues to lash down!

The rain is VERY HEAVY now at The Stoop.

Not an afternoon where I'd want to be out there to be honest.

Let's hope those conditions don't ruin what's been a very enjoyable game so far.

"Harlequins will be delighted with that half-time scoreline - 19-7 up against a Saracens side who are still the reigning champions.

"Marcus Smith running the show for Harlequins in that first 20 minutes was very impressive.

"Saracens showed in that last 10 or 15 minutes that they are not out of this, there is a lot of quality in that side."

Owen Farrell, one of Saracens' greatest ever servants, has spoken to BBC Sport about the disappointment surrounding the salary cap scandal that has rocked his club.

While the fly-half is away preparing for the Six Nations with England, the plight of Sarries has been inescapable.

Manu Vunipola kicks to touch off the back of a Saracens scrum and that is that for the first 40.

But, it's pretty much been all about Harlequins.

Cadan Murley with two of their three tries and they have really put on a show so far.

Let's hope for more of the same after the interval.

Bit of a kicking exchange ensues as the rain keeps coming down.

It ends up in a Saracens line-out just inside their 22.

Almost a second Sarries try as Alex Lewington shows both his speed and vision with a run and then kick over the top.

The bounce not in his favour though as Danny Care can collect close to his try line and kick out of touch.

Sarries miss the chance to capitalise off the next line-out after a knock-on.

Easy now gents!

Chris Robshaw and Callum Hunter-Hill exchange a few words after Robshaw knock-on but then kicks the ball clear downfield before the whistle goes.

Earlier, Aaron Morris found himself picked up by three Sarries players, so they're still fighting (literally and metaphorically) in this one!

The rain is back at The Stoop and there's a break in play as a few bumps and bruises are tended to on both sides.

Let's hope the weather doesn't spoil what's been a free-flowing contest so far.

Just goes to show you can't keep a Saracens side out of a game for long.

But as mentioned, that was their first real chance to get any sort of attack going.

Alex: What does Marcus Smith have to do to get picked by England? Proven operator in the Prem for almost 3 seasons, great skills and vision. Can see him going the way of Cipriani - mercurial talent but not quite right in England’s eyes.

There is no doubt that Smith has shown what he is capable of today.

Sarries look shell-shocked by this display so far.

Absolutely spot on from Hugh Godwin there as Quins have given them no sniff of a chance to get going in attack so far.

"There is certainly no fluke to it. There is not luck in this scoreline because they have created these tries with their own good play and finished them when it has not been easy to do so.

"Saracens haven't had any chances at the other end."
