New Newport Gwent Dragons signing Tom Prydie scored 5 tries on his debut for Wales Under 20s as they romped to a 119-7 win over Japan at St Helens last night.
Wales thrilled an enthusiastic home crowd with a confidence boosting display of end to end rugby from the start.
Coach Danny Wilson said: "I am delighted by the way we stuck to our game plan and kept our shape. It was a clinical performance with some great tries which proved the level of potency we have in our backs.
"To be fair to Japan they never gave up and provided us with the sort of workout we needed leading into a tough Junior World Championship group."
Wales face Fiji in their opening game on 4 June in a group which also features holders New Zealand and Samoa.
