Wales winger Morgan Stoddart marked his first game back from injury with a try in a 24-13 win for Scarlets against Dragons.
Stoddart had been out of the game for 15 months following the broken leg he suffered against England in the summer of 2011. But after being introduced to the fray at the start of the second half he only had to wait half an hour before celebrating a try on his return.
Following a penalty apiece from Steffan Jones and Aled Thomas, Scarlets scored the opening try of the night in controversial fashion.
A Thomas penalty kick from the right hand side appeared to go through the posts but, to the bemusement of the Dragons players, referee Nigel Owens ruled that the kick had narrowly missed the far upright and awarded a try instead once Gareth Maule - alert to the fact the ball was still 'live' - touched the loose ball down in the left hand corner.
Thomas converted and added two further penalties to hand the home side a 16-3 half-time lead.
After a drab, scoreless third quarter, played out in persistent rain, Dragons threatened a mini fightback.
Dan Evans' smart grubber kick on the left hand touchline appeared to be covered by a back-tracking Scott Williams, but the ball escaped from his grasp and Adam Hughes followed up smartly.
His score and the subsequent conversion closed the gap to just three points.
Jonathan Evans's sin-binning on 65 minutes stopped the Dragons' momentum and resulted in three more penalty points for the Scarlets from the boot of replacement Rhys Priestland.
After being brought down just short of the line a minute earlier, winger Stoddart made no mistake in finishing off another attack for what was the most popular score of the evening.
