RGC 1404 opened up a three-point lead at the top of SWALEC Division One East after a crucial 27-13 home win against 13-man Treorchy at Eirias Park.
The bonus-point victory means the north Wales side leapfrog Ystrad Rhondda into pole position having played a game more than their south Wales rivals. Two red cards for the visitors did not overshadow what was a comprehensive win with a late try from Rhodri Evans securing the bonus points for the northerners.
In the only other game in the division to have survived the weather, Gilfach Goch humiliated Tredegar in a 52-0 romp to keep the winless visitors at the bottom of the table.
Elsewhere, in Division Two, Garndiffaith heaped more misery on lowly Tylorstown after claiming a 24-14 bonus-point victory.
