Early drama in the second half as Samson Lee is sent to the bin for dragging his boot along Danny Care's face.

And that try brings a half to a close. A shock is on the cards here, Harlequins will have to up their game a good bit if they are to go on and win this game. Scarlets are in scintillating form and are dominating this game. Check back with us in 10 minutes for the second half.

What a player!

Try Scarlets! Wow what a brilliant try from inside centre Scott Williams. He gets the ball around 60 metres out and breaks through 2 Quinns players, throws one dummy, goes another 10 metres and throws another dummy, he then uses great pace to get to the line on what is the try of the round so far. Brilliant effort. Conversion sails over from Rhys Priestland and Scarlets lead 20-10.

great play!

Brilliant

Great score.

Try Harlequins! Nick Evans chips through a ball and it gets a favourable bounce and falls into Nick Easter hands, he manages to offload and find Mike Brown who manages to get through 2 defenders and score. Conversion is good from Evans so score is now 13-10 to Scarlets.

Harlequins go close through Tom Williams but he is pushed out into touch.

Scarlets go over again but it's held up. Harlequins all over the place at the moment.
