WING Ewan Rosser scored a double as Dragons Under-18s extended their lead at the top of the Regional Age Grade Championship with a 45-3 victory over the Ospreys.

And a commanding performance in tricky conditions at Aberavon saw them move 14 points ahead of the Scarlets before Tuesday’s clash Ystrad Mynach.

Dragons, captained by Ben Carter, led after six minutes as Rosser, brother of first team speedster Jared, pounced on a loose ball before Ospreys hit back with a penalty from Joe Hawkins.

Fly half Will Reed extended the lead and converted his own score on 19 minutes before wing Morgan Richards went over in the corner. The bonus point was wrapped up flanker Ollie Howard just before half-time.

The flow of points continued as Rosser scored a length of the field interception.

Replacement Carrick McDonagh added a sixth try before centre Lewis Bates cut a fantastic line in the final minute to wrap up the big win.
