HOLDERS The New Saints crushed Gap Connah's Quay 5-0 to set-up a final meeting with Airbus UK Broughton.
In the second of two one-sided semis, Scott Quigley claimed a hat-trick as the Nomads failed to reproduce the form that had seen them twice defeat TNS in league games in recent weeks.
Quigley broke the deadlock following a goalmouth scramble and, a minute later, Matty Williams curled a shot past John Danby into the bottom corner to double the lead.
Five minutes before the break, Jamie Mullan scored a third when he chipped the ball over the onrushing Danby.
Quigley got his second on the hour from Ryan Brobbel's through ball and claimed his hat-trick when beating two defenders before firing into the top corner.
