Lightning-quick substitute Paul White lit up a drab engage Super League basement battle at the Galpharm Stadium.

There was little to choose between two poor teams until super-sub White entered the action midway through the first half and hit the Vikings with two tries in seven minutes.

The Giants scored again either side of half-time to race into an unassailable 28-4 lead and, although Widnes hit back with three second-half tries, they finished a well beaten side.

The Vikings lost a cutting edge when stand-off Owen Craigie went off injured before half-time but it was their shabby defence that will have most concerned coach Frank Endacott.

They drew first blood on four minutes when loose forward Simon Finnigan took Mark Smith's flat pass from dummy half to slice through a gap in the home defence to touch down.

Steve Rowlands' conversion kick rebounded back off a post, a sure sign that little was to go right for the visitors.

Huddersfield, who had lost their previous three matches, drew level on 11 minutes when impressive hooker Brad Drew kicked to the corner for prop Eorl Crabtree to touch down.

The game was going nowhere until introduction of the pacy White transformed the Giants.

He got on the end of the best move of the match involving full-back Paul Reilly and stand-off Chris Thorman to score with his first touch of the ball on 26 minutes.

He also finished off a break by powerful second rower Stuart Jones six minutes later for his second, fending off some weak tackling in the process, and Reilly maintained his side's momentum with a solo try two minutes before the break.

Thorman, who tormented the Widnes defence with his pinpoint tactical kicking, kicked three of the four conversions to put his side in firm control by the break.

A refreshed Drew, who returned at half-time at the expense of the two-try White, broke clear from his own half and the supporting David March got winger Marcus St Hilaire over for Huddersfield's fifth try.

The Giants looked to have scored again when towering forward Paul Smith stretched out of a two-man tackle but the try was disallowed by the video referee after three minutes of replays.

The let-off seemed to give the visitors encouragement as they struck with two tries in five minutes to give themselves a glimmer hope of getting back in the game.

Finnigan took Hulse's pass to score a carbon copy of his first try on 50 minutes and then centre Aaron Moule beat St Hilaire one-on-one to touch down at the corner.

Moule then added his second on 68 minutes, snaffling possession to break up a dangerous Huddersfield attacking move and showing his pace on a 90-metre sprint to the line.

Rowlands was able to convert just one of his side's four tries and Huddersfield had the final say when St Hilaire followed up March's kick to the corner for his second try, to which Thorman added his fifth goal.
