Builth Wells remain top in Division Two West but they will do well to keep looking over their shoulder at ever-improving Bridgend Athletic.
Flanker Andrew Duggan scored the game's only try as Builth made hard work of seeing off struggling Penclawdd, 13-6 at the Groe. And it is just that lack of tries that could undermine their title credentials.
The Bulls have won five from five but only once have secured a bonus point and that means Loughor, 28-23 winners over Ammanford, are just one point behind with a game in hand.
But sat on both their shoulders are Bridgend Athletic who are also unbeaten after easing past Kidwelly 36-13. Athletic are still eight points behind the leaders but with two games in hand and a red hot finisher in their ranks such as Rob Coles, who took his scoring streak to seven tries in three games with another double, they must be taken seriously.
