St Patrick's Academy Dungannon came out on top in a keenly contested quarter-final derby in Maghery.
It was close in the first half, with Liam Gervin and Ryan Devlin supplying Dungannon points and Tom Murphy and Conor McNally on target for Armagh, before Harry Og Conlon scored the Tyrone side's first goal in injury-time.
In the second half, Conlon found the net again and, although James McLaughlin responded for Armagh, it was Dungannon who were the better side, with Gervin netting late on.
