With the stadium officially opened by First Minister Rhodri Morgan, the game was only three minutes old before the first try was scored. Centre Jonathan Davies kicked deep into Barbarians territory which saw winger Matthew Jacobs collect and dive over in Brain Carney's tackle. Ceiron Thomas added the conversion to give the home side an early 7-0 lead.
The Barbarians, with 10 different nationalites in their line-up, weren't afraid to throw the ball round with Cardiff Blues full-back Ben Blair showing quick feet in one burst but he was left clutching thin air on 14 minutes when Davies was put into a gap by fellow centre Gavin Evans and the big midfielder side-stepped Blair to race clear to give Thomas an easy conversion for the Scarlets to extend their lead to 14-0.
Davies was to the fore again six minutes later when he weighed up the options in front of him before off-loading a perfect pass to the flying full back Morgan Stoddart who raced clear without having a hand placed on him. Again Thomas added the conversion to take the score to 21-0.
The Barbarians eventually got on the score sheet in the 37th minute after the invitational side went through the phases. The ball was flung wide to Irish winger Carney who went over in Jacobs tackle.
But the Scarelets finished on a high note in the first half when Stoddart burst clear to scorch over for his second try to send the home side into the tunnel with a comfortable 26-5 lead at the break.
Davies, who was a proving a constant menace, showed his power when setting up next try. The 'Pembrey Powerhouse' Phil John, who had only been on the park a matter of seconds, collected his pass and trumbled within touching distance of the try-line before setting up a ruck. Scrum-half Martin Roberts then darted from the base to scoot over to gift wrap another Thomas conversion.
The game then went through a scrappy period before the Scarlets scored their sixth try after Darren Daniel broke through the Baa-Baas defence to send Gavin Evans clear. With Thomas adding another conversion, the Scarlets held a healthy 40-5 lead.
The Barbarians then hit a purple patch with three tries in quick succession to Blair, Jeremy Staunton and Thomas de Vedia but it wasn't enough as the Scarlets fans began to celebrate their official opening in style.
