Blues South under 16s maintained their push for a place in the final of the WRU Age Grade Championship with a bonus point victory over the Dragons at Taffs Well.
With four of the six sides still in with a chance of reaching the final, the South were in desperate need of a four-try success over a Dragons side who, along with North Wales, have no chance of escaping the pool.
And they achieved that with aplomb, winning 34-8 to secure maximum points.
Centre Ceiron Driscoll set the trend with an early try and with Rhys Patchell converting and adding two penalties, the South were soon 13 points to the good.
Full back Corey Allen added a second try and Reuben Tucker a third before JB Bruziller sealed the bonus with a fourth after the interval.
Patchell finished with 14 points whilst for the Dragons, Daniel Hall crossed for a try that Rhys Stevens improved.
