Neath players will enjoy the bragging rights in Ospreys training this week after the Welsh All Blacks ran out 29-5 winners over Swansea at the Gnoll.
The hosts dominated throughout and led 19-0 at half-time and despite dreadful conditions which turned the pitch into a mud bath, the sides produced a cracking game. From a break by inside centre Jonathan Spratt, his midfield partner Stephen Thomas crashed over for a try in the opening minutes.
It was one way traffic for Neath as wing Richard Johnston grabbed a try before former Scarlets fly half Gareth Bowen converted both tries as well as kicking five penalties. The Whites had just a second half try by hooker Ashley James to show for their efforts.
