The game got off to a nervy start with a knock on from the kick-off and then a dropped pass. But once the young Bulls got into their stride there was simply no stopping them.
Price showed off his pace to bag his first try with a 50 metre sprint to the line after a great counterattack from their own 22 by Builth. Outside half Rhys Davies added the extras off the right touchline.
The Athletic hit back with a try of their own from James Puaca and did their best to keep pace with their unbeaten rivals. They created plenty of half-breaks but just weren’t able to turn them into points.
A Davies penalty increased the Builth lead before one of the players of the season for the Bulls, centre Alecs Williams carved his way through the middle to cross for a scintillating try that Davies improved to create a 12 point gap.
From there on the lead continued to build as Price completed his hat-trick to make it 27-5 at the break. The second half started with another brilliant solo effort from Builth, this time No 8 Iwan Coyle displaying a full range of skills.
The seventh try came from replacement wing Morgan Price and Davies ended with three conversions and a penalty to complete the job and put the final seal of approval on a never to be forgotten season at the mid Wales club.
To their credit, Bridgend Athletic had the final word when livewire scrum half Evan Dadamo crossed for a consolation effort.
