Dragons RFC aces Walker Price (2), Huw Anderson and captain Harri Ackerman all scored as two late tries ensured Wales won a thrilling opening game in the Under-20s Six Nations against Scotland.
Wales outscored their visitors six tries to five in an entertaining 37-29 encounter in Colwyn Bay.
Scotland led through a brace of tries by both Elliot Young and Freddy Douglas, plus a score for Kerr Yule.
But a late yellow card proved costly as Price and Rhodri Lewis wrapped up a bonus-point win for Wales in coach Richard Whiffin's first game in charge.
Price had already scored in the first half while Anderson, Morgan Morse and captain Ackerman also crossed to hand Wales a first success in the competition for two years.
Dragons duo - prop Jordan Morris and lock Nick Thomas - also featured for Wales on a successful opening night.
