SKEWEN could still snatch the division two west title after they produced a fine display to win 29-14 at fourth-placed Trebanos.
Maesteg Quins could have wrapped up the championship on Saturday but they crashed to a 40-10 defeat at Felinfoel, who rose to eighth as a result — and could finish as high as fifth if they win their final game at home to bottom-but-one Aberystwyth next Saturday.
The Quins actually led 10-8 at half-time but their hectic schedule over the past few weeks caught up with them and Felinfoel ran in some fine tries.
Fly-half Aled Roberts, scrum-half Luke Marsh, No. 8 Curtis Morris, wings Elliot Dawe and Jordan Dunne and lock Lawrence Holcombe all crossed, and Roberts landed two penalties and two conversions.
Skewen ran in four tries at Trebanos, two for wing Mark Harvey and one each for centre Cameron Morris and No. 8 Wayne Mitchell. Fly-half Anthony Buselli put over three conversions and a penalty.
Full-back Tom Dew scored the only try for the Swansea Valley side, with Matthew Edwards putting over three penalties.
Skewen trail Maesteg Quins by two points and both have one game each left to play — both away to winless bottom side Aberavon Quins, Maesteg Quins on Wednesday and Skewen next Saturday.
Skewen also play Llandovery in the final of the Brains SA West Wales Cup at Dunvant on Wednesday, May 14 (7pm).
Mumbles finished the season in sixth spot, level with Amman United on 53 points but above them by virtue of having won one game more.

In the other game in two west, Newcastle Emlyn beat visitors Aberavon Quins 38-25.
