St Mary’s and Peel will clash in next weekend’s Ascot Hotel Junior Cup.
First half goals from Dan Hutton and Jamie Corkill ensured the Saints saw off surprise semi-finalists the Police 2-0.
Peel came from behind at Douglas Road to knock out holders St George’s and set-up a repeat of the 2009 Junior Cup Final.
Stuart Morris had given the Geordies a half-time lead but two goals from Callum Gallagher, the second a penalty, booked the westerners' place in combination football’s end-of-season showpiece, despite finishing the match with 10 men.
