AN Anthony Gelling try eight minutes from time was enough to give Wigan a nervy victory over Hull KR.
Teenager Joe Burgess was handed his Warriors debut with Man of Steel Sam Tomkins missing due to a virus and put in a solid performance, making a number of good runs and tackles.
With just under quarter of an hour on the clock and the Warriors nudging the Rovers’ line, a well executed left to right move saw Blake Green miss out Darrell Goulding to send Charnley racing in.
Jordan Cox had to leave the field minutes earlier in an oxygen mask after a lengthy stoppage but the away side responded to Wigan’s score almost immediately.
A mix-up at the kick-off saw Wigan concede a drop-out after referee Richard Silverwood had initially given the penalty to Wigan and Eden strode through a gaping hole in the defence after Michael Dobson directed him through with the simplest of short passes.
Wigan wasted opportunities and they were severely punished when Michael Dobson backed himself from 30 metres out to finally get the score the Robins had been probing for.
But a neat Matty Smith kick through the line to Charnley as the half-time hooter sounded gave the jet-heeled winger a space he needed to feed Goulding with the desperately needed points which Charnley improved to draw the sides level.
Five minutes after half time, Lincoln Withers had been sin binned for mucking around at the play the ball when Ryan Hampshire was trying to get on with it and a slick Goulding pass saw Charnley crash over by the corner post with Eden on his back.
The four-point battle was on a knife edge until Gelling took Green’s pass in the 73rd minute to stroll in and Smith banged a drop-goal over for good measure to give breathing space.
But with four minutes to go Evran Tuimavave crashed over and Dobson converted to ensure a cagey last few minutes as Wigan led by five.
But they held on to reclaim their lead at the top of the table at least until Huddersfield face Salford on Sunday.
