Last year's beaten finalists Wigan were stunned when Jack opened the scoring just before half-time, thumping in Luke Varney's cross.

And Maynard rounded off the win when he converted another Varney cross in the 90th minute.

Paul Scharner and Emile Heskey failed to convert Wigan's best chances.

The Latics, with five changes to the side that drew 2-2 at Everton at the weekend, shaded the opening period.

But they were generally restricted to long-range efforts and never convinced in their search for an equaliser after the interval.

However, Alex goalkeeper Ben Williams made some fine saves when called upon - particularly when he tipped Heskey's late effort round the post.

Earlier, Scharner had headed straight at Williams when he could have done better.
