Joy Ralph became the youngest scorer in DLR Waves history as she hit a brace from the bench on her senior debut at the UCD Bowl.
The striker, who turned 16 two weeks ago, put the gloss on a fine performance as Waves blitzed Treaty United 5-0 on the opening day in Belfield.
Fellow debutante Lynn Craven opened the scoring late in the first half before Kerri Letmon and Avril Brierley found the target after the break.
