Ronnie Stam conjured a late equaliser to secure a 1-1 draw for Wigan and leave high-flying neighbours Bolton bitterly frustrated.
When on-loan Benfica forward Rodrigo Moreno, 19, produced a delightful finish to put Owen Coyle's men ahead in the 54th minute, the stage was set for the Trotters to emerge victorious.
Wigan had already lost Tom Cleverley to injury in the 12th minute and goalkeeper Chris Kirkland was carried off on a stretcher shortly after the hour mark. But Stam stabbed home at the far post in the 80th minute to draw Wigan level and earn a booking for his celebrations in front of the visiting supporters.
