Ryan Turner, Ross Powell, Kevin Ellis, Chris Owen and Chris Jones all crossed as the home side romped to a bonus point.
BP Llandarcy and Kidwelly are battling it out for the second promotion spot, with just one point separating them after the weekend's results.

Newcastle Emlyn are just a point away from sealing the Division Three West championship after a narrow win over strugglers Cardigan.

Crymych kept up the pressure on second-placed Llandeilo with a 35-25 win at Haverfordwest. Tries by Gut Griffiths, Kenneth James, Rhodri Davies and a double by Gareth Davies means Crymych can still clinch promotion if Llandeilo slip up.

Tondu are still in with a shout, as they lie two points behind after drubbing Brynamman. Doubles for wing Craig Fox and flanker Andrew Evans helped them to a seven-try, 45-10 win.
