In Swalec Division Two East, the top three all maintained their 100-per-cent start to the season while the bottom three all continued their winless start.
First up, Tredegar recorded a 57-13 triumph over Llantwit Farde. Tom McPhearson, Craig Lloyd and Ronnie Kymes all scored twice while Anthony Simmons and Rhys Hallett crashed over for one apiece. The bonus-point win means the league leaders have now secured 25 of 25 available league points.
Mountain Ash also continued their winning run but were unable to secure the bonus-point in a 29-11 win over Penarth. Dean Phillips and Craig Evans both touched down while Josh Lewis was in imperious form with a 19-point haul.
Then Llantrisant completed the streak with a 39-7 victory over Penalta at Cefn Mably, Matthew Griffiths, Martyn Griffiths and Owen Osbourne among the scorers.
But it was Rhydyfelin that stole the show in the division, with an 11-try thumping of Caerphilly.
The Cheesemen could do nothing to stop a rampant Rhydyfelin outfit that blew the visitors away.
Liam Watton raced away for a hat-trick, Kieron Phillips and Dylan Hughes both grabbed two, while Scott Pritchard, Kirk Richards, Rhys Godwin, Damien Spencer, Dylan Phillips and Dave Gratton all touched down once.
Abergavenny’s Howard Davies was the story of Division Three East. The 49-year-old prop answered an SOS to turn out for his local club after three years out of the game. His loyalty to the shirt was rewarded with a try in a 37-14 bonus-point win over Croesyceiliog.
Davies was joined on the scoreboard by centre Jack Flower, wing Andy Watson with two and fullback Ryan Williams.

In a mid-table battle, Newport HSOB beat Pill Harriers 30-28 thanks to a last-minute penalty. The hosts had looked destined to fall short after tries from Tom Diggle, Matthew Rees and John Burgess but Will Edwards stepped up in the dying moments to land his third penalty and pinch the win.
In Division Four East, newly-promoted Senghenydd won the bragging rights in a top-of-the-table clash at Chepstow.

Meanwhile, New Tredegar got off the mark to record their first win of the season at Crumlin. Phillip Davies, Dewi Winston, Aled Davies and Colin Jones scored the tries for the visitors and, to their relief, a last-minute Crumlin drop-goal sailed wide of the posts to give them a narrow 31-29 victory.
Ammanford’s 100 per cent start to the season in Two West came crashing down as they travelled to Cwmllynfell.
Wing Trystan Lewis and prop Craig Kelly tries helped Cwm to a 19-10 lead. Ammanford rallied late on but missed a late conversion and the hosts held on to win 19-18.

Crymych are still unbeaten in Three West, but they were pushed all the way by battling Llandeilo.
Wing Guto Griffiths scored the visitors’ only try but they were made to sweat on their 13-12 lead as Llandeilo missed a last-minute penalty that would have stolen the points.
