Wigan winger Josh Charnley scored two tries to extend his lead at the top of the Stobart Super League chart but earned a rebuke from his coach for failing to kick a goal.
The Warriors outscored Huddersfield by seven tries to two to win 32-12 in tonight's table-topping clash at the Galpharm Stadium and pull two points clear of their hosts.
It was comfortable in the end, with Wigan scoring 20 unanswered points in the last half-hour, with centre George Carmont also scoring two tries, but coach Shaun Wane admitted he was concerned for a time over his team's poor marksmanship.
Charnley, kicking in the absence of the injured Pat Richards, missed all four attempts before handing over the job to Sam Tomkins, who kicked two from three.
"I know Josh is not a normal kicker but he needs to kick them," said Wane. "If Pat Richards plays today, we score another 10 points.
"I was just concerned it was going to cost us. We will always score tries but we need to make sure we kick better than we did today."
Wane was happier with the rest of his team's performance as they avenged their opening-round home defeat by the Giants.
"I thought we scored some great tries," he said. "We had to concentrate on our defence in the first half.
"But to score seven tries against a team like Huddersfield - I'm a great admirer of Nathan Brown and the way he coaches - and to keep them to two, I'm fairly satisfied with that.
"The main thing is we wanted to win game more than them. The character and desire made me very happy."
Huddersfield led 6-0 thanks to winger Jermaine McGillvary's 15th-minute try and they were still in the hunt when full-back Greg Eden touched down early in the second half to make it 12-12.
But they tailed off badly and coach Brown had no complaints over a second consecutive league defeat that casts doubt over their title credentials.
"The opposition were too good for us tonight," he said. "They are a very good team and in a couple of key facets of game were better than us. You've got to take your hat off to the opposition.
"I thought a lot of damage was done in the first half, when their kicking game was very good. They strangled us a bit with their ball control and field position.
"The pleasing thing is we still caused them a lot of trouble with minimum field position and not much possession.
"I thought David Fa'alogo was terrific and Greg Eden was as dangerous as Sam Tomkins in a well-beaten side. He's a wonderfully talented kid and he should take some confidence out of the game."
