A late drop goal from Zak Hardaker helped Wigan move to within two points of third-placed Hull FC following a 15-14 victory.
The Black and Whites had come from 14-6 behind to level the game, only for Hardaker to win the match with nine minutes remaining.
Hull had gone ahead through two Marc Sneyd penalty goals before Liam Marshall’s first – a penalty try, put Wigan ahead.
Furter penalty goals saw Wigan 10-6 ahead at half-time, but Marshall’s second gave Wigan a strong eight-point lead.
However, Scott Taylor barged over, Sneyd converted and kicked another penalty goal to bring the game level, before Hardaker’s winning moment.
