And the chance goes begging.

Marnus van der Merwe peels off the drive but is stopped short of the line, pinged for holding on, and that is that for the first half.

Immediate response from Scarlets and now they have a penalty 20 metres out.

Carwyn Leggat-Jones duly puts his side in the corner and although the drive comes up short, another home infringement follows.

Another lineout, another chance. Big moment this...

Benetton are grinding Scarlets down here and scrum-half Andy Uren, well known in England from his decade at Bristol, is pulling the strings.

After what seems like endless hit-ups from the pack, another penalty comes and this time, Rhyno Smith declines the three points in favour of a close range line-out.

Munster have done well to work themselves back into the game and flanker Sean Edogbo is popping up all over the place with some big carries.

Glasgow have a strong wind at their backs and will want to add to their lead before they turn into it in the second half.

First chance for Macs Page to attack out wide but his attempted chip and chase drifts out on the full.

The youngster may have been better served taking the contact there.

Moments later, Jac Davies is hammered back as he takes a high ball and it's another Benetton penalty.

Well this is rare - a game where both sides seem intent on taking every three points going. Hope for the purists yet.

Again Scarlets look to compete at the breakdown but again, it's untidy and Mr. Brace hands Rhyno Smith a simple chance in front of the posts.

The Rhyno duly obliges.

This time Benetton get the scrum penalty despite a retreating pack. Referee Andrew Brace spotted something in the Scarlets shove there and wasn't happy.

Nicolas Roger Farias boots his side up to the 22 and one again, Scarlets have some defensive work to do.

This time, no mistake from Rhyno Smith and after enjoying 75 per cent of the possession so far, Benetton are level.

More Benetton pressure with a series of carries before Marnus van der Merwe thinks he's won a turnover.

Instead, the South African hooker is pinged for going off his feet and the hosts have a chance from 25 metres.

Argentina sevens star Ignacio Mendy breaks a tackle and kicks ahead but Jac Davies is there to cover.

The full-back then so nearly cuts free in his own 22 but is tap tackled then forced into touch.

Fortune so nearly favoured the brave there.

Great work from Scarlets!

Benetton lock Giulio Marini takes clean lineout ball and a forward drive follows.

But the visitors repel it, legally, and win the turnover. Of course, players then celebrate like they've just been presented with the William Webb Ellis trophy but such is the modern way.

Gareth Davies won't thank his forwards for that one.

From a defensive line-out, the ball is messily tapped back to him.

Davies collects the hospital pass and clears in a hurry but from the pressure that follows, Benetton have a penalty and go to the corner.

First URC start, first kick nailed for Carwyn Leggatt-Jones.

He can thank his front row for that one. They gave the visiting pack a shunt at the scrum and the pressure yielded the penalty.

Scrum penalty for Scarlets and the easiest of three points on offer.

And now a chance for Scarlets.

This time it's a sloppy play from the Benetton pack and in possession in their own 22, the ball goes forward.

From the scrum, Fletcher Anderson picks up and carries powerfully towards the post and then.......guess what, there's a knock-on at the breakdown.
