Former Cardiff City youth player Kane Owen fired Penybont FC’s winner in their JD Welsh Cup tie against Undy Athletic.
Defender Owen, 22, kept his cool to scored from a penalty during the last few seconds of the extra 30 minutes.
A few weeks earlier Penybont crushed Undy 8-1 in a league match at the Kymco Stadium, but the visitors were far more competitive in the cup tie.
There were few chances for either teams, although a Marcus Griffiths header just cleared the bar.
The decisive moment during extra time came when a shot struck the arm of an Undy defender and the referee awarded a spot kick.
Owen stepped up, stayed calm and sent Undy’s keeper the wrong way to score.
Penybont’s reward is a home tie against Monmouth Town in the second round.
Former Merthyr Town striker Josh Bull netted Cwmbran Celtic’s winner at Caerau (Ely).
It was the second time in a fortnight the teams had met. Celtic had won the first 5-0, but Caerau manager Nanah Bah had signed five new players and they were far more competitive.
Bull fired the winner when he ran onto a pass down the middle, drew the goalkeeper and scored with a clinical finish.
Llandudno Albion, who play in Welsh Alliance Division One, won 3-2 against four-times Welsh Cup winners Rhyl.

Albion have been handed a trip to Buckley Town in the second round.
