Glasgow 34 - 20 Scarlets

Another dose of gloom had looked on the cards as Glasgow made a disastrous start but wing Evans lit up Firhill with a marvellous two-try display which propelled them to a crucial bonus point.

Scarlets – determined to make amends for their hammering by Edinburgh last weekend – made a stirring start and capitalised on early pressure by surging in front after only four minutes.

They patiently amassed a series of phases before Lions playmaker Stephen Jones ducked inside Moray Low to reach the line.

Gradually Glasgow battled their way back into the match only to squander a golden opportunity to level matters.

A thrilling dash by Lome Fa'atau and Evans set up full-back Bernie Stortoni 30 metres out but indecision allowed the Scarlets to backtrack and snuff out the danger.

And there was a further blow for the Warriors midway through the half as the visitors grabbed their second touchdown.

Fa'tau was robbed just inside his own half, presenting Mark Jones with a cruise to the line. Stephen Jones added the conversion to stretch the gap to 10.

Dan Parks eased some of the jitters by slotting a simple penalty and that was the cue for Glasgow to move into gear at last.
