An inspired second-half display earned rampant Widnes only their fourth win of the engage Super League season as Huddersfield collapsed at a sunny Halton Stadium.

After a terrible start to the campaign, Frank Endacott's side have started to show signs of a mid-term renaissance.

And although the Giants came to the north west as one of the form teams in the division, they had no answer to a barrage of powerful, incisive attacks from the Vikings.

The visitors played their part in an entertaining first half, which ended 12-12, but the Vikings dominated a one-sided second period, with hooker Shane Millard at the forefront of all their attacks.

Winger Gray Viane was the tormentor-in-chief for the hosts, grabbing a hat-trick of tries, with further scores coming from Daniel Frame, Simon Finnigan, Millard and substitute Mark Smith.

Huddersfield had started well, however, and the game was only three minutes old when they scored the opening try.

Eorl Crabtree sent Ben Roarty away with what looked like a forward pass inside his own half and the dextrous loose forward fed Paul March to scamper home under the posts.

Michael De Vere converted, then added a penalty to give his side an 8-0 cushion after just six minutes.

There was no let-up in the game's breakneck speed and within minutes, Widnes had reduced the deficit.

Owen Craigie fired a flat pass out to Frame, who skirted one challenge, side-stepped full-back Marcus St Hilaire and raced over with a helping push from team-mate Craigie.

A conversion and penalty - both slotted handsomely over by Stephen Myler - levelled the scores in what was already proving to be a tight contest.

The visitors regained the advantage with the simplest of tries in the 20th minute when Chris Thorman passed short for second-row forward Paul Smith to barge over in the right corner.

But with five minutes left in the half, the first handling error of the game allowed the Vikings to restore parity once again.

Viane picked up a loose ball 15 metres from his own line and with Giants' cover nowhere in sight, the jet-heeled winger raced clear and over.

The second period started scrappily but Widnes soon took control and managed to get their noses in front for the first time in the afternoon in the 48th minute.

Giant prop Julian O'Neill broke through some powder-puff defending and laid off to loose forward Finnigan, who evaded a last-ditch tackle to crash over.

Huddersfield were failing to keep possession and they conceded a fourth try moments later when hooker Millard, who had a tremendous game as always, received replacement Smith's pass to ground.

Both tries were converted, giving the hosts a 12-point lead.

Widnes were unstoppable and after good work by Millard, again, Finnigan and Sala Fa'alogo, Viane went over for his second try of the match.

The wideman completed his hat-trick - and sewed the game up - after the Giants defence was again cut to shreds on the hour before former Wigan forward Smith got amongst the try-scorers with 15 minutes left.
