Offaly survived Wexford’s brave fightback to win the All-Ireland Intermediate camogie title 2-12 to 2-10 at Croke Park.
The Faithful girls held a commanding nine points lead at half-time, but manager Karen Barnes made the changes that mattered, and her side came roaring back to draw level.
But a late surge carried Offaly through, and they finished with a scoring blitz to secure the Jack McGrath Cup.
Dermody grabbed her first goal in the eighth minute, a rather fortuitous effort, lofted in from long range and deceiving goalkeeper Helena Jacob on its way to the net.
Skipper Michaela Morkan was a dominant figure at centre back, launching a series of attacks as Wexford tried in vain to get some momentum going.
Midway through the half, the Slaneysiders were still looking to open their account, while the Faithful had racked up a 1-5 scoreline.
Two points each from Jean Brady and Siobhan Flannery and a Dermody effort opened out an eight points lead, before Ciaran O’Connor finally got Wexford off the mark in the 16th minute.
Fiona Rochford and Lisa Bolger tagged on points, and with Bolger beginning to look dangerous up front, it looked as if Wexford could turn the tide.
But Dermody cut inside Louise O’Leary to finish to the net from close range in the 29th minute to give Offaly a 2-7 to 0-4 interval lead.
Louise Codd moved to midfield to turn in a sterling second half display for a resurgent Wexford side, and Fiona Rochford’s solo goal on 45 minutes reduced the deficit to four points.
Ciara O’Connor added a superb point, before Rochford blasted home her second goal on 49 minutes to bring the sides level.
Offaly had scored just one point in the opening 20 minutes of the half, a Dermody free, but Joachim Kelly made a raft of substitutions to refresh their challenge, and they finished strongly to fend off the challenge.
Points from Arlene Watkins, Flannery and subs Emma Dunne and Ailsa Hughes saw Offaly over the finish line.
