TREBANOS kept their 14-point lead at the top of division three south west with an 18-8 win at neighbouring Vardre.
Trebanos's midweek Silver Bowl quarter-final against Ystrad Rhondda that went to extra-time appeared to have taken its toll as they failed to reproduce their best form against second-from-bottom Vardre.
(Trebanos were eliminated from the Silver Ball after extra time finished 24-24 by virtue of being drawn out of the hat as the 'home' side, even though the game was played at neutral Glynneath.)
On Saturday, wing Matthew Edwards scored all their points with two tries, two penalties and a conversion. For Vardre, Jamie Taylor scored a try and Josh Humphreys put over a penalty.
Second-placed Ystalyfera edged to a 21-17 win at Maesteg Celtic.
Centre Ceri Myers and No. 8 Owain Morgan got their tries, with fly-half Gareth James putting over three penalties and a conversion.
And third-placed Mumbles squeezed home 24-20 at home to Bryncoch to leave themselves five points behind Ystalyfera but with three games in hand.
Andrew Littlehales, playing at blindside flanker, scored two tries and centre Lee Rimmell one, with Greg Davies adding three penalties.
Ninth-placed Resolven won 36-26 at home to sixth-placed Morriston.
Fly-half Darren Bowen and hooker Nicky Reed got two tries each for the Neath Valley side, and scrum-half Lloyd Morgan and lock Richard Davies also crossed. Centre Dale Mead converted three of them.
For Morriston, No. 8 James Evans and fly-half Anthony Evans scored tries, the latter converting both and kicking three penalties and a drop- goal, Morriston's first of the season.
Neath Athletic came perilously close to throwing away a 24-0 half-time lead at home to bottom club Aberavon Green Stars before eventually winning 27-21.
The Athletic raced into a big lead after tries by wings Luke Lewis and Luke Thomas, scrum-half George Rees and fly-half Adam Rowland plus two conversions by Rowland. But after the break, with the bonus point in the bag, all they could add was a Rowland penalty as the Stars scored tries via prop Kristian Griffiths and centre Andrew Harris, plus a penalty try, and three conversions by No. 8 Keirion Mattocks.
