Ooh we have a foot race here.

Ellis Mee and Owen Watkin are chasing a kick to the Scarlets try line.

Mee gets there first and the danger is over, for now.

Another Scarlets attack thwarted as Ellis Mee has the ball ripped from his possession by Kieran Hardy.

Scarlets are getting plenty of ball, they just don't seem to be clicking today.

Dwayne Peel can't hide his frustration in the stand.

Jake Ball is tough as old boots.

He shakes it off and goes straight back in the scrum.

The Scarlets are varying the point of their attack really well, Ospreys have done well to not let them score this half.

Keelan Giles has been good today mainly with his defensive effort, covering across and working the backfield.

Jake Ball looks in pain here, his knee buckles in the tackle by Ross Moriarty.

Ben Whitehouse blew up straight away and the medics are on.

Keiran Williams and Harri Deaves combine well to win back possession for Ospreys.

Williams with the chop tackle and Deaves straight in for the turnover.

That's two great takes in the air by Jack Walsh.

Scarlets are going to have to improve their kicking game if they're to put the Ospreys full-back under pressure.

It's a scrappy start to the half, with both sides making unforced errors.

Both sides have made half-time changes

Henry Thomas and Jarrod Taylor are on for Scarlets, while Rhys Davies is on for Ospreys.

Dan Edwards gets us back under way at Parc y Scarlets.

There's 40 minutes to decide who takes the west Wales bragging rights.

The Scarlets have played the better rugby in the first-half, just a couple of lapses in concentration have let them down.

The Ospreys came back into the game and almost took it over in the last 15 minutes.

Scarlets will be wondering how they are trailing at half-time here in Llanelli after they have been more dominant, especially early on.

But Ospreys have been more clinical in attack and they have been resolute in defence.

Scarlets end the half on the attack, but Ryan Elias loses the ball forward and the whistle goes.

Both sides head for the warmth of the tunnel.

Harri Deaves has just given Welsh rugby a reminder of what a fine prospect he is.

The Ospreys flanker evades several tacklers before he is brought down.

Great response from the Scarlets. Superb play by Ellis Mee to pick off Keelan Giles, that was really composed play by the Scarlets.
