Widnes Vikings stormed back to the top of First Utility Super League courtesy of a 36-18 victory away at Huddersfield that condemned the injury-hit Giants to a third consecutive defeat.
After Chris Dean opened the scoring in the 12th minute, former Giant Kevin Brown produced a fine cut-out pass to send Stefan Marsh in and then saw full-back Aaron Murphy spill his up-and-under that allowed Charly Runciman to open up a 16-0 lead.
But the Giants, whose injury problems mounted when Jamie Ellis suffered a shoulder problem, regrouped and crossed through Michael Lawrence, having exchanged neat passes with Jermaine McGillvary, in the 34th minute.
However, Widnes extended their advantage to 22-6 at half-time when Macgraff Leuluai crashed over from close range.
Marsh went in at the corner a minute after the restart and fellow winger Corey Thompson crossed twice, either side of Larne Patrick pulling a try back for the Giants, who had the final say as Jamie Foster converted his own try in the last minute.
The win was Widnes' first away at Huddersfield since the advent of Super League and coach Denis Betts warned the real test will come as they battle to stay top over the next month.
"We've not won here for 20 years and it was a great overall performance," Betts said. "There are things in there we can do better - Joe Mellor was finding ways not to score a try.
"The lads are really made up with the fact we've been away from home three times and we've come out with six points from four games. We would have taken that early in the year.
"This next month the games are going to be coming thick and fast and it will be a real test for us. It becomes a war of attrition and the squad gets tested. It's nice (to be top) at this stage, we've made a really good start but we've got to make sure we get a bit more ruthless."
Poor performance by us today! No excuses at all, poor from the start. Best thing is we get to do something about it next week. #coyg— Leroy Cudjoe (@Elroy_cudj) February 28, 2016
Huddersfield go in search of that elusive first win against bottom-placed Leeds Rhinos, also winless, on Friday.
"Historically that's a top-three game but both teams have copped some injuries and it will be a survival of the fittest," said Giants coach Paul Anderson. "Let's see who can throw out the healthiest team."
Ellis joined the likes of Danny Brough, Eorl Crabtree, Joe Wardle and Kyle Wood on the sidelines.
"Three quarters of our salary cap have watched today," he said. "One or two might have a chance for Friday but we've got to battle on. The key is to stick together. I thought Widnes were very good, we were poor and pretty soft if I'm honest.”
