Tondu extended their unbeaten run at the top of Division 1 West with a 30-13 win at Glynneath in a rain-drenched weekend of rugby.

The bottom-of-the-table clash between Aberavon Quins and Skewen was postponed due to a waterlogged pitch, but there were victories for Loughor away to Ammanford and a narrow win for Kenfig Hill at home to strugglers Carmarthen Athletic.
Waunarlwydd's comprehensive 42-17 at home to Llangennech ensured they remained hot on the heels of second-placed Cwmllynfell, whose match against Kidwelly fell foul to the weather.
In Division 2, Builth Wells extended their lead at the league's summit to three points following a 15-3 win at home to Aberystwyth.
