THE great entertainers of British rugby sailed into the PRO14 final with a thrilling first half performance to have the game won by the interval.
Scarlets weren't quite as breathtaking as they were in their memorable European Cup win at Bath back in January but still scored three tries to further their quest of retaining the PRO14 title.
Head coach Wayne Pivac said: “We knew we had to start well to keep the crowd quiet and we were clinical in taking our chances.“
The first came after only three minutes when the hosts conceded a couple of needless penalties.
Straight from the kickoff Glasgow captain Ryan Wilson set the tone by charging into an opponent to gift the Welsh a platform in the home 22 from which Gareth Davies gave Rhys Patchell the chance to round a defender to score.
A second try soon followed when a powerful run from Scott Williams saw him brush aside weak tackling to provide Gareth Davies with an easy run-in.
At that stage, the visitors looked as if they could score at any time and it came as no surprise when the third and best arrived.
A loose kick from George Horne was collected by Johnny McNicholl before intricate passing from Steff Evans and Gareth Davies resulted in Ricky Evans galloping over.
Glasgow's response was a penalty from Finn Russell so they trailed 21-3 at the interval before Scarlets sealed victory when Ken Owens finished off a driving line-out after Nick Grigg was yellow carded for illegally playing the ball in a ruck.
Grigg returned and Glasgow dominated the final quarter with he and Jonny Gray scoring tries but it was still a miserable night for a team who had collected 49 points from a possible 50 in their home matches in the PRO14 this season.
They lost Stuart Hogg before kick-off with food poisoning and too many of their players were out of sorts with Russell having a particularly disappointing evening on his final start for the region before he joins Racing 92.
Only Fraser Brown and Gray matched the industry of the Scarlets up front with centres Grigg and Sam Johnson causing problems but only when the result wasn't in doubt.
Warriors' head coach, Dave Rennie said: “We didn't fire any shots in the first half and gave away too many penalties so we spent too much time in our half.
“Once we qualified for a home semi-final sometime ago, there hasn't been the same sort of sting to our game.“
Scarlets had that sting with Patchell's lengthy kicking and the flair of Gareth Davies ensuring that the efforts of their dominant pack were rewarded.
Owens and Aaron Shingler excelled and the only blot was the loss of John Barclay, who was helped off with an achilles injury.
The 31-year-old is likely to miss next week's final when Scarlets travel to Dublin where they were trounced 38-16 by Leinster only three weeks ago.
Pivac said: “Leinster are the benchmark and last time it was a tough one to take but we hope for a better display.“
On his last match before departing for France, Russell said: “It's not the way I wanted to go out, but that's sport.“
