Llandudno entertained Cefn Druids at Giant Hospitality Stadium and the hosts started brightly with Aron Hughes and Morgan Owen going close.
The first half ended goalless, but Llandudno were rocked when Joe Carey had to go off injured.
His replacement, Osian Jones, was full of energy and led the line well with Aron Hughes playing just behind him.
Iwan Jones was played through and his cutback picked out Sean Mcaffrey’s run and he slotted home.
Llandudno’s second goal quickly followed after a Mcaffery corner was spilled by goalkeeper Adam Jones and the ball was judged to have crossed the line.
Jones made amends soon after when Morgan Owen went for goal and his shot took a deflection deflected. The effort was superbly tipped round a post.
Druids pushed for a goal, but the Llandudno rear-guard held firm to maintain the clean sheet and progress into the quarter finals where they play Airbus UK Broughton at home.
