Michael Clare and Dai Llewellyn came off the bench to score and help the first team continue their promotion momentum.
Poor winter weather has seen four consecutive games postponed, but after 56 day lay off, the firsts showed little rust with an accomplished win at Abertridwr Park, completing a league double over their hosts.
After a goalless opening hour, striker Clare broke the deadlock with his fourth goal of the season. That looked like it might be enough but Ben Thornton equalised for the home team. However, Ponty would have the final word when Dai Llewellyn rolled back the years with an injury time winner to keep the Black Sheep three points clear of the chasing pack at the top of Division One.
