Andy Moore and Shane Williams crossed for superb second-half tries as Neath defeated Swansea for their first win at St Helens in six seasons.

Steve Winn notched a late try for the Whites to ensure a grandstand finish to the Celtic League encounter, but Neath were able to hold on.

The match came to life just past the hour when scrum-half Moore swooped for his touchdown after excellent work from Sean Marsden, Dave Tiueti and Leigh Jarvis.

The Welsh All Blacks then struck again when Williams dabbed down a sublime kick over the top from Moore to celebrate his 100th Neath appearance in style.

Jarvis converted both tries and his kicking was to prove a telling factor.

Throwing caution to the wind in the final stages, with Kevin Morgan standing out, Swansea hit back after Arwel Thomas put Winn over.

But the centre's score was too little, too late despite a conversion from Thomas.

Until the late flurry of action, the match had been a mediocre affair.

Neath's Shaun O'Connor claimed the only points of the first half with a drop goal, but skill levels were generally low.

O'Connor also converted a penalty and Swansea's Gavin Henson was successful with three kicks.

Countless passes hit the ground and the kicking on both sides was often aimless.

Swansea's cause was not helped when they had skipper Scott Gibbs sin-binned for what the referee saw as illegal use of the boot at a ruck.

But the match was in the balance until Neath coach Lyn Jones tilted proceedings his side's way with second-half substitutions, one of which brought on the impressive Hywel Jenkins.
