KRIS Leek led the way with a brace as Goytre set-up a Gwent derby against Cwmbran Celtic in the fourth round of the Welsh Cup with a 4-2 victory over Caernarfon Town.
The Huws Gray Alliance Canaries controlled the first half but, despite creating a number of chances, they were unable to break the deadlock at Plough Road.
And Iwan Williams' men paid the price when the Welsh League Division One leaders grabbed the tie by the scruff of the neck with four goals in a 23-minute spell after the break.
Josh Jones made the breakthrough with a 54th-minute strike and before the hour Leek had doubled the home tally.
Leek struck again on 74 minutes and Calum Miles added another after 77.
Caernarfon bagged two quick consolation goals through Jamie Breese and Jamie McDaid on 78 and 83 minutes respectively, but the Alliance side made the long journey home disappointed.
