After a tricky start they lived up to their favourites tag. Four-try Sam Tomkins led the way with a 10-minute hat-trick which took his tally to 21 tries in nine games. David Hodgson had touched down for the Robins before two tries in five minutes from Tomkins put the favourites in front.
Pat Richards, Josh Charnley and Iain Thornley also touched down for Wigan. Craig Hall reduced the arrears with two tries, but a Liam Farrell score ahead of Tomkins' final try secured an impressive win for the Warriors.
For some time, this was not the walkover it was expected to be in the wake of Wigan's 84-6 win on the same ground last month. Rovers were brutal in the opening half-hour and rattled Wigan with a series of booming hits but could not stay the course at that intensity.
That David Hodgson touched down Michael Dobson's early kick only added to Wigan's woes and they would have been in more trouble had Hall shown better composure when clean through. But, after sorting out their system in the wake of Blake Green's withdrawal through injury and, more importantly, their discipline, they got on top thanks to two tries in the five minutes before half-time from Tomkins.
Sam Powell's kick was dropped under no pressure by Omari Caro and, in the subsequent set, Tomkins kicked through and Greg Eden, rather than falling on it, kicked it back up for him and the ball was dotted down.
Richards converted both and Wigan headed to the dressing rooms 12-4 ahead and with a sense they had broken their hosts' spirit. But, if that was not true at the time, it was five minutes after the break.
Typically Tomkins was the man on the spot, claiming his hat-trick next to the sticks after a break and inside ball from Richards, who tagged on an extra two. Then, two minutes later, they swapped roles, with Tomkins kicking through for the waiting Richards.
By the time Josh Charnley scored in the corner - three minutes later - some home fans had rounded on coach Craig Sandercock, whose contract situation is going to be reviewed in the coming weeks. A more primary concern may be a review of their defending as Iain Thornley stripped past two men to go the length of the field for a sixth score.
A response finally arrived when Hall dotted down a loose one following a Charnley knock-on, but Wigan quickly got back into their stride as Liam Farrell pushed his way through with 14 minutes left. It would have been fitting for Tomkins to have the last word and it looked as though he would when he kicked and chased for a fourth, but Hall responded for Rovers to wrap up the scoring with a charge down.
