CEFN Druids stunned Cardiff Met in the capital with a 3-1 victory thanks to a brace from Alex Mudimu and one from Neil Ashton.
Mudimu opened the visitors' account on 13 minutes and, although Chris Baker equalised for the Archers, Mudimu got his second just before the hour mark. Ashton completed the scoring before the hosts had Baker red carded in the final minute.
In the Play-Off Conference, Barry Town lead the race for seventh spot after a 2-1 away win at Newtown with goals from Ryan Newman and Kayne McLaggan, either side of one from Nick Rushton. All three goals came within the first 18 minutes and neither side found a way to goal after that.
A 90th-minute Marc Williams goal clinched a 3-2 home win for Llandudno over Carmarthen Town, who had striker Aiden O'Kelly red-carded four minutes earlier. Danny Shaw put the Seasiders in front, but Liam Thomas headed the Old Gold level. The lead was restored by assistant manager Matty Williams, but a Dwayne Coultress goal appeared to have secured a vital point for the struggling visitors until Williams settled the contest.
