Wrexham will fly the flag alone for North Wales in the Welsh Cup semi-finals following a comfortable win at the LHP Stadium.
The second-place Adran Premier side took an early lead against their Adran South hosts, Faye Knox breaking through on 13 minutes, heading in from an Ava Suckley assist.
Katie Barker was next on the scoresheet on 35 with her 19th goal in all competitions this campaign.
Suckley then deservedly found the target in the 45th minute with a wonderful chip over the keeper, Phoebe Davies assisting.
The outstanding Suckley made it a brace midway through the second half, Mariam Mahmood involved in the build up and Knox reached 13 goals in 15 outings for the side with a powerfully-struck late fifth.
Super Suckley provided the second assist to add to her pair of goals.
Adran Premier giants Swansea proved far too strong for their North Wales visitors, who would have lost by a bigger margin but for some fine stops from goalkeeper Meg Robinson.
First-half goals from Jessica Williams and Maisie Miller put the home side in control of the tie, and a brace from Taite Trivett after the break, a Jess Mills own goal and a further strike from Maddy Murray sealed the result.
Swans were on top from the start and after 10 minutes Aimee Deacon was through, but Llandudno’s Robinson produced a superb save to turn the effort around the post for a corner.
The two home goals came, but it would have been more had Robinson not done really well to keep out a free kick.
After the torunaround, the lead increased to 4-0 before the Adran North visitors went close, Erin Doran’s first-time effort met by a sharp reflex save from the Swansea goalkeeper to preserve the clean sheet.
Two more home net-finders followed, but Robinson was again in fine form to keep out a powerful Emily Richards shot.
