Llanelli more than played their part in this Principality Premiership encounter but two late tries off the bench from Wales Under-18 scrum-half Harri Morgan sent them to defeat at the Brewery Field.
The Sospans looked to be on their way to a second victory of the season and first on the road until 17-year-old Harri Morgan, making his senior rugby bow, won it for the Ravens in the last 10 minutes.
Despite falling 10-0 behind inside the opening 10 minutes Llanelli ended the opening half firmly in the ascendency.
Fly-half Cai Evans – son of former Wales, British and Irish Lions and Llanelli wing Ieuan – booted the Ravens into a fifth minute lead with a penalty.
It was the hosts who then got the first try of the afternoon on nine minutes when full-back Tyler Williams finished off a nice Dylan Moss-led breakaway down the right with Evans making light work of a tricky conversion out wide. Moss was also making his first start for the Ravens.
Ioan Hughes got Llanelli on the scoreboard in the 22nd minute with a penalty and they were level nine minutes later when full-back Tom Rogers dived over with Hughes adding the easy extras to make it 10-10.
The visitors then went in front on 36 minutes when a rolling maul was driven over by hooker Taylor Davies and, although the conversion was missed, they led 15-10 at the turnaround.
Evans, another Wales U18 star, landed a penalty 10 minutes after the re-start while replacement Billy McBryde landed one from long range three minutes later.
The turning point came on 70 minutes when replacement Morgan was sent clear by Rhodri Apsee and he raced away to score with Evans once again taking care of the extras.
Morgan was over again before the end, with Evans converting.
Bridgend 27-18 Llanelli
