Barry Town AFC moved to within three points of the leaders after a 3-2 victory over Cwmbran Town FC.
However, the Seasiders needed a last-minute goal from striker Jamie Moralee to claim the points after Cwmbran's Gareth Wharton had brought the visitors level on the hour-mark.
Barry had gone ahead through Jamie Jenkins' strike shortly before half-time but Cwmbran levelled immediately through a Jon French own goal. Wharton then scored at both ends before Moralee's late clincher. The win edged Barry a step closer to their ninth Welsh Premiership title in ten seasons.
