Builth Wells remain top in Division Two West but they will do well to keep looking over their shoulder at ever-improving Bridgend Athletic.

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.
