Wigan made the short journey to St Helens and prevented their hosts from collecting the League Leaders’ Shield with a brilliant performance to secure a 10-30 victory.
Wigan began the game without Sam Tomkins, who had to withdraw with a knee problem, which game an opportunity to Oliver Partington, who came onto the bench,with Morgan Escaré taking over at fullback.
The Warriors scored three first-half tries, with two from Dan Sarginson and one from John Bateman, with a conversion by George Williams, to take a 0-14 lead.
Saints replied on the stroke of half-time with a brilliant try by Tommy Makinson, who collected a cross field bomb from Danny Richardson to make the half-time score 4-14.
In the second half Wigan extended their lead through Tom Davies, before Makinson added his second and Richardson’s goal made it 10-18.
But then Gildart scored a spectacular long distance try, rounding Ben Barba brilliantly, and Sean O’Loughlin added another when he took a smart dummy-half pass from Sam Powell.
It means that Saints will have to wait another week before picking up the League Leaders’ Shield.
