Aberavon may have won the Welsh National League Division One title for the last two seasons, but they will remain in the division against next season.

The 49-14 win gave Caerphilly an overall aggregate of 66-27 and fly half Luke Richards led the way with 24 points from a try, five conversions and a hat-trick of penalty goals.
Other tries for Caerphilly came from Taunaholo Taufahema, Simon Grainger, Sione Mone Tuipulotu, John Colderley and a penalty try with former Wales full back Matthew Back crossing twice for Aberavon and New Zealander Scott Leighton goaling both tries.
