Scarlets eventually run out of steam and options as Lewis Rawlins spills the ball in a tackle.
Scarlets are carrying the ball into the teeth of the wind and against a gutsy defence. They're over 20 phases now. Who'll crack first?
Gordon Bulloch
Former Scotland international on BBC Radio Wales
"You'd expect the wind to play to Glasgow's advantage in the second half, but Scarlets are making much better use of it."
Pat MacArthur makes way at hooker for Glasgow with Fraser Brown taking over. At the same time James Eddie comes on for Jonny Gray.
Gareth Davies takes over at scrum-half from Aled Davies for Scarlets and Lewis Rawlins comes on for Rob McCusker in the back-row.

Liam Williams is such a classy player and a big loss to the Scarlets. Glasgow back in front but Scarlets are digging in. John Barclay, the Warrior in exile, has a great intensity about him
Glasgow captain Josh Strauss is in the thick of the action as Glasgow hammer away at Scarlets' defence.
Glasgow's starting XV boasted 196 caps between 13 players. Scarlets had nine Test players as they took to the field with 168 Tests under their collective belts.
But Glasgow had 117 caps on the bench to call on, including prop Euan Murray's 62. Once-capped scrum-half Gareth Davies could not compare with that on Scarlets' bench, leaving the overall tally as: Glasgow 313-167 Scarlets.
But will it pay off for the hosts?

Scrum V's pitchside reporter
Phil Steele on Liam Williams' pain: "It looks like it's a right shoulder injury.
"The fact that he's come off and not gone straight down the tunnel is a positive thing.
"Hopefully it's just a stinger."
DTH van der Merwe comes on for Sean Lamont on Glasgow's wing.
Andy Nicol
Former Scotland scrum-half on Scrum V
"That try was all down to number eight Josh Strauss and the amount of yards he made into the Scarlets defence.
"How good has he been tonight? His ball-carrying has been outstanding."
Jordan Williams takes over from Liam Williams at full-back for Scarlets.
Liam Williams goes off with a shoulder injury.
Finn Russell adds the conversion from the left-hand touchline. Great kick in these conditions.
It's been awarded. Peter Murchie did enough to beat the touchline.
Peter Murchie hopes he'll be awarded this one, in the left-hand corner.
Rhys Priestland will be hoping Glasgow scrum-half Niko Matawalu is as lively for Bath as he has been tonight. Matawalu is also joining Bath next season.
