Newport Gwent Dragons centre Jack Dixon added to his collection of records on Monday. He already holds the record for the youngest player to appear in a Welsh regional match and has now became the youngest player to play at a Junior World Cup when he started for the Wales Under 20s in Monday’s win over Fiji.
Jack was joined in the starting line-up was fellow Dragon Jonathan Evans but new signing Tom Prydie missed out, despite being originally named on the wing, after being quarantined with illness.
Wales came back after trailing 12-3 at half time to win convincingly by 44-18.
Touchdowns from Daniel Thomas and Eli Walker put Wales in front, before the floodgates opened with scores for Darren Harris, Cory Allen, Matthew Morgan and captain Cory Hill.
Wilson was delighted to avenge Wales' shock 38-24 defeat to the south sea islanders in last year's tournament and hopes his side can build on the performance ahead of their next match against defending champions New Zealand on Friday.
"It's a very pleasing result especially after last year. We were keen to put things right after that," said Wilson.
