The Scottish region were seven points down at the break but tries from Stafford McDowell (2), George Horne – who tallied a total of 15 points thanks to his efforts from the tee – Johnny Matthews and Rory Darge ultimately proved decisive.

Scarlets led on several occasions but were hampered by a yellow card for Sam Wainwright in the second half, Steff Evans providing their only try of the game while Sam Costelow kicked 12 points.

Glasgow were excellent during the opening exchanges and opened the scoring when centre McDowell skipped past two defenders and went over on four minutes, scrum-half Horne adding the extras.

Buoyed by their home support, Scarlets grew into the game and eventually notched their first points when Costelow slotted a penalty on 25 minutes.

A second three-pointer from the fly-half reduced the deficit further four minutes later as the hosts began to pile on the pressure, and they would finally notch a try when wing Evans finished off a brilliant move out wide.

Costelow couldn’t convert but he sent Scarlets into the break with a 14-7 lead when he dispatched a third penalty from in front of the posts in the final act of the first half.

But Glasgow were back on the front foot following the restart and crossed for their second try on 43 minutes as the second-row pairing of JP du Preez and Scott Cummings combined before Horne managed to get the ball grounded.

Horne’s conversion levelled the scores and Scarlets were delt a further blow as Sam Wainwright was shown a yellow card for a high tackle on Rory Darge in the build-up to the score.

However, the 14-man Welsh region were back in front moments later as Costelow struck his fourth penalty of the game.

That lead didn’t last long, though, as Glasgow made their numerical advantage count, replacement hooker Matthews powering over at the rear of a maul, Horne adding the extras again.

Despite Scarlets returning to their full complement, Glasgow wrestled further control just before the hour mark as they pounced on a wayward home lineout and flanker Darge eventually forced his way over.

Scarlets threw everything at Glasgow over the remaining minutes but couldn’t convert their late pressure into points, and as their hopes of reaching the final slipped away, McDowell finished off a slick lineout move to compound their misery, Horne converting for a fifth time.
