Tonna held on to win against Pontardawe in the Boxing Day game at The Gnoll.
Tonna took an early lead when full back Nicky Fisher squeezed in for a try which wing Josh James converted but Pontardawe replied with a try by prop David Morris and the visitors took the lead through a penalty by outside half Steffan Rees.
Pontardawe went further ahead when Rees crossed for a try to make it 15-10 at halftime. Both sides vied for supremacy in an evenly-fought encounter and Tonna took the lead when referee Craig Davies (Briton Ferry) awarded them a penalty try to make it 17-15.
Both sides had chances and Pontardawe missed two late penalties – the second of which rebounded from the left upright – before Tonna cleared their lines
and, when Ponty’s last-gasp move hit the touchline, the final whistle sounded to give Tonna victory..
