Carmarthen Quins in name but a Scarlets Development XV in reality made up for their defeat at Jersey the previous week to record a three tries to one win in this British and Irish Pool Five Cup game at Parc Y Scarlets.
A strong rally in the last quarter in which they scored three unanswered tries earned them a deserved victory, albeit in a disappointing game.
Fly-half Josh Lewis put the Quins into a 10th minute lead but Albion drew level with an excellent penalty from opposite number Lawrence Rayner.
Lewis restored the home lead with an equally good penalty but the fly half was then yellow carded for a dangerous tackle.
The Albion suffered at the scrum and full back Steff Evans punished them with a close range penalty before wing Jake Hendry took advantage of an overlap to get the visitors the first try of the game, converted by Rayner for a 10-9 interval lead.
Rayner’s second penalty made it 13-9 and with replacement prop James Gibbons shoring up the Albion scrum he soon made it 16-9.
The Quins were surprisingly fragile at the line out and could not find any rhythm in a continually fractured game and had to rely on replacement fly-half Dan Jones to close the gap to four points.
The game at last sparked into life when a great counter attack led by wing Lee Williams and Steff Evans ended with flanker Shaun Jones racing home from 20 metres and a 17-16 lead.
The Quins at last had their bit between the teeth and started to string things together in more confident fashion.
Victory was sealed when a line out drive ended with a try for replacement Gethin Robinson before flanker Will Boyde picked up a loose ball to gallop in, Dan Jones converting.
