Huddersfield climbed above Warrington in the scramble for top six places, taking control in the second half of an enterprising game with the help of two intercept tries.
Rod Jensen and Kevin Brown were the key architects of the victory, although Warrington did not help themselves by missing all but one of their kicks at goal.
It was the home side, though, who seized the early initiative through Lee Briers' 40-20 kick. From that, Ben Westwood was held up over the line but Henry Fa'afili stole in down the blind side.
The Giants seized their first chance too, with Ryan Hudson darting over and Chris Thorman adding the goal. Hudson's lost ball then gave Warrington the chance to strike back immediately, with Adrian Morley sending Westwood over. But Huddersfield hit the front after 24 minutes, when Morley's knock-on gave them the possession from which Hudson set up Brad Drew.
Thorman landed the conversion, leaving Warrington to draw level before half-time when Kevin Penny touched down.
The Giants regained the lead with an extraordinary try, Jensen intercepting almost on his own line and going the length of the field to score despite Penny's electrifying chase.
Warrington's frustration was underlined when Morley went on report for his third high tackle and Paul Rauhihi was penalised for lifting in the tackle, giving Thorman two extra points.
An altogether less satisfactory try took Huddersfield clear, Drew kicking through and Jamahl Lolesi being credited with the touchdown. The gap was now daunting, but Westwood's strength took him over only for Brown to then pick off Briers' pass and stroll over.
The excellent Westwood completed his hat-trick and landed his side's first goal but it was all too late.Reuse content
