Danny Wilson's side collapsed after looking in control at half-time

The host's 35-10 triumph brought Glasgow's five-match winning run to an end.

Tries from Steff Evans, Scott Williams, Gareth Davies, Sione Kalamafoni and Ryan Conbeer earned the Scarlets their first win in five games in all competitions.

Rhys Patchell, Evans and Sam Costelow also kicked 10 points between them.

All Glasgow could muster was a try from Johnny Matthews and five points from the boot of Duncan Weir.

Glasgow dominated the opening exchanges in Llanelli and led 10-0 through a Matthews try but, as they've shown too often this season, an inability to turn pressure into points returned to haunt them.

Tries either side of the interval put Scarlets in control but Glasgow scrum-half Jamie Dobie looked like he'd put Warriors back in front after nice work from Ollie Smith but referee Chris Busby adjudged Ryan Wilson obstructed opposite number Blade Thomson from making a tackle.

That was as good as it got for Warriors as Scarlets stretched away and round off Glasgow's misery they lost Oli Kebble, Ollie Smith and Cole Forbes to injury and Sam Johnson, Fraser Brown and Jack Dempsey to illness.

Glasgow head coach Danny Wilson: "It wasn't like us. We've gone well recently and it was a second-half collapse.

"It was a mixture of poor execution from us and very good attack from the Scarlets, along with injury and illness with us having to make a whole host of changes.

"The week has led to that a little bit. We thought we were in control of the game at half-time but we didn't get enough points for our pressure.

"We conceded 14 turnovers in the second half as opposed to three in the first half. We'll have to bounce back quickly from that."
