Osian Williams has had a good game tonight, he's done the important work that he needed too.

This is tense as we enter the closing stages, and the greasy ball is causing some problems.

Cardiff will have a scrum just outside their 22 and will need a clean exit.

Scarlets will look to put the pressure on against the head and then chase down Taine Basham if he runs it out.

Cardiff are driving line-out specialists.

Scarlets' defence wasn't tight enough there and Evan Lloyd broke off the side.

Three tries out of four from their driving line-out positions.

Botham and then Basham with charges into the 22. Evan Lloyd reaches for the line but knocks on.

Back for a Cardiff penalty against Tristan Davies for offside. They kick to the corner.

Scarlets with a chance in the 22 but the greasy ball is knocked on.

Cardiff bang clear and then Blair Murray drills one. It's out on the full.

Big momentum swing after the ball lands on the line (clearly, despite some home howls towards the officials!).

Big defensive set from Scarlets, which earns a roar of approval from the home fans.

Ellis Mee with a good spot, blitzes and a wins a penalty.

Heading into the final quarter.

Johan Mulder is more than happy to go to his kicking game, his kicking is very good.

Will the rain impact tactics? Looks like it with Cardiff getting some joy from box kicking.

It was a lovely sunny day but the rain is now absolutely hammering down in Llanelli as we have a break in play while Mason Grady gets a cut treated.

He'll go off to get that sorted. That's another rejig with scrum-half Ellis Bevan on for the wing.

Ryan Elias and Will Evans come off for Scarlets, John McKee and Alex Groves on.

Cardiff are putting the Scarlets under pressure but they just seem to be kicking the last ball away when they don't need to.

They've let the Scarlets off the hook a few times, keep the ball and keep putting the pressure on.

Another unplanned replacement for Cardiff with Cam Winnett forced off after a bump.

Harri Millard on for him, with Jacob Beetham moving to full-back.

Cardiff have had most of the possession and have controlled things so far in the second half but they haven't converted it into points and the Scarlets take the lead.

Cardiff probe away without luck and the attack ends with Le Roux Malan kicking a grubber dead.

They finally turn to their bench with flanker James Botham on along with hooker Evan Lloyd, prop Rhys Barratt and fly-half Jarrod Evans.

Will the playmaker make a big impact after his return from Harlequins?

Josh McNally is pinged for offside and that soft penalty gives Hawkins an early chance from the tee.

No mistake and Scarlets are in front.

Should Cardiff have opted for a three-pointer?

Eddie James has been superb tonight.

His tackling, his running with the ball, his footwork, he's had a superb game.

Gareth Anscombe was signed to rival Sam Costelow and Carwyn Leggatt-Jones for the 10 jersey.

They are both injured, so it is Wales centre Joe Hawkins covering fly-half and he is introduced for the new boy.

Four replacements by the Scarlets already.

Cardiff get a line-out wrong for the first time.

Knocked on, much to the delight of feisty 20-year-old Scarlets lock Will Evans.

That leads to Adam Jones giving a chat to both captains, and then penalising Cardiff for "escalating it".

Ferocious defence by Scarlets on their line to prevent Cardiff from going over.

The visitors were playing with penalty advantage.

It's right in front of the posts but Cardiff go for the corner. That's the modern approach...

Wonderful improvisation by Cardiff fly-half Callum Sheedy, who heads a loose ball forward to keep his side on the attack.

That will be clipped up for social media, no doubt.
