Super League leaders Warrington's 100% winning start came to an end as they were edged out by second-placed Wigan in a derby classic at the Halliwell Jones Stadium.
First-half tries from Jake Wardle and Brad O'Neill earned the Warriors a 10-0 lead.
Warrington hit back with a converted try from Wigan old boy Matty Nicholson.
But Harry Smith closed the door with an early second-half penalty before taking his team out of reach with a drop goal.
Warrington had two second-half tries chalked off, the second of them less than a minute from time when it was controversially ruled that Greg Minikin had lost control of the ball in touching down.
But Wire would still have needed to score again. Second-placed Wigan were worthy winners on the back of their first-half performance, when they wasted several great chances to have built an even bigger lead, largely down to the slippery rain-sodden ball.
