Blues North under 16s warmed up for this month's WRU Regional Championship final against the Ospreys with a 35-20 victory over the Dragons at Abercynon.
Having swept through the pool stages of this season's competition without defeat, the North struck another blow for the region with five tries and 10 points from the boot of outstanding outside half Ian Smerdon.
Smerdon, James Woods and Lloyd Peart out the hosts into a 25-5 lead with Dean Gunter and Chris Phillips adding second half triws to secure another bonus point victory.
The Dragons helped themselves to first half tries from Jack Flower and Chris Attwell with Craig Howell and Chris Moseley scoring after the interval.
In the other game, Blues South gained an honourable draw, 17-17, against the Scarlets at Narberth. Steffan Phillips and Rhys Gingell crossed for tries for the home region with James Stephenson adding two conversion and a penalty for good measure.
However, Blues South who are rooted to the foot of the table, grabbed a share thanks to tries from Dan Fish and Ed Doe plus two conversions and a penalty from Loren Quick.
