Rianna Jarrett’s goal seven minutes from time secured Wexford Youths' spot in the Continetnal Women's National League Cup semi-final.
Niamh Prior had given UCD Waves a first-minute lead in a windswept Jackson Park in the 1-1 draw and the home side had other chances to score theough Emily Cahill, Aine O'Gorman and Julie-Ann Russell.
Wexford captain Kylie Murphy volleyed high and wide on 56 minutes with Ashling Frawley driving the ball at UCD keeper Monica McGuirk five minutes later.
The visitors saved a point late on when Jarrett rose high to fire past McGuirk. The result ensures Will Doyle's side advance to the final four with seven points. UCD must meet Cork City WFC to decide the semi-final line-up as they currently have four points, while City have three.
On Saturday evening, Shelbourne Ladies FC secured top spot in Group B following a 12-1 victory over Castlebar Celtic.
Rebecca Creagh opened the scoring for the Red Pandas after 10 minutes with Jamie Finn and Creagh striking again to make it 3-0. The goals started to flow after that with Noelle Murray netting a hat-trick.
Pearl Slattery, Alex Kavanagh, Siobhan Killenn, Megan Lynch and two more from Murray rounded off the scoring, while Rachel Kearns was on target for Castlebar.
Elsewhere, Lauren Kelly’s third goal of the season secured three points for Peamount United as they overcame Cork City WFC 1-0 at Bishopstown in the Continental Tyres Women’s National League.
Peamount almost found the breakthrough early in the second period when Claire Kinsella got free of her marker, but she failed to convert. It didn't matter though because Kelly tapped in late on to seal the win.
The victory was Peamount’s first away victory this season and sees them remain sixth in the WNL table.
