Wigan extended their Championship lead to six points with a deserved victory over Leeds at Elland Road.
After a subdued opening 45 minutes, Wigan exploded into life only 39 seconds into the second half.
Jason Roberts slipped the ball to Alan Mahon, who rifled his shot into the top left corner from the edge of the box.
And six minutes later, another Roberts pass sent Jimmy Bullard clear and he took advantage as Gary Kelly backed off to slot past an exposed Neil Sullivan.
Leeds boss Kevin Blackwell
"I thought we got caught out with lack of experience on two or three occasions. But apart from that, you wouldn't have been able to say who was top and who was near the bottom of the table.
"It's frustrating for the kids but I'm proud that we put up a good show.
"There are a lot of youngsters there and there were no inexperienced players in the Wigan side and I think at times it showed."
Wigan boss Paul Jewell
"We were better than Leeds in the whole match but in the first half I thought we were anxious at times.
"I thought at times we over-indulged but to keep them at bay so comfortably is a testament to the team.
It's a great strike from Mahon and the second goal, Jason's held it up well and we had two against one. We kept our shape well and on the day we were too good for Leeds."
