Cardiff Blues A suffered a tough defeat at the Brewery Field on Friday night as Gethin Jenkins and T Rhys Thomas gave a number of U18s a chance to experience senior rugby.
Theo Bevacqua, Ethan Lloyd, Mason Grady, Jacob Beetham, Rhys Anstey and Theo Cabango all either started or came off the bench, while players from the Championship and BUCS Super Rugby also got the opportunity to play at a higher level.
There was also a group of Cardiff Blues Senior Academy players and it was one of those who opened the scoring in Bridgend as Teddy Williams pushed over from close range after a period of dominance from the away side.
Unfortunately that would be the last points the visitors scored, as the Ospreys Development side took control of the game, but not without a fight.
Two tries and a penalty for the home side gave them a 5-15 half-time lead as Cardiff Blues stayed in the game thanks to some strong breakdown work from back-rowers James Botham and Tim Grey in particular.
Unfortunately discipline was the issue for the away side in the second half, as Ospreys fly-half Josh Thomas was able to kick three penalties to extend the lead, before a late try from Travis Huntley wrapped up the win.
A disappointing scoreline for the young Cardiff Blues team but plenty of opportunities for a number of exciting future stars, as well as giving club players from around the region valuable experience of professional rugby.
Next week sees Gethin Jenkins and T Rhys Thomas take their side on the road for the final time of this Celtic Cup campaign as they travel to Cork and Irish Independent Park for a game against Munster on Friday night.
