Caernarfon Town’s Louis Lloyd’s late goal proved the difference as title holders The New Saints were consigned to 2-1 defeat on their full return to Cymru Premier action.
Last weekend Welsh domestic football’s European flagbearers had their game at Briton Ferry Llansawel abandoned because of a waterlogged pitch.
That was TNS’ first attempt at returning to the league since putting up a brave display in a 2-0 defeat at Fiorentina in the Uefa Conference League.
Back at their Park Hall home, Saints went ahead through Leo Smith after 12 minutes.
Zack Clarke’s equaliser ensured the visitors were level by the break and Lloyd broke the deadlock to give his side victory in the 82nd minute.
It was a second successive home defeat for TNS and their third loss of the campaign.
For Caernarfon it was their first win at Park Hall since November 2018.
