Wigan Athletic's Development Squad are champions of the Central League after Tuesday afternoon's 2-1 victory at Morecambe.
The Latics youngsters travelled to the Globe Arena needing to match the result of second-placed Rotherham, whom they beat 9-0 at Christopher Park last week.
And they finished the job in style with another three points.
England starlet Joe Gelhardt set them on the way with the 19th-minute opener, pouncing on a loose ball in the home area.
And Charlie Jolley doubled the lead midway through the second period with a calm finish.
A nervy finish was ensured when Ben Hedley pulled one back for Morecambe from the penalty spot with a couple of minutes remaining.
But Latics held on and were able to kick-off the celebrations on the full-time whistle.
