Sheffield United's Under 23s fought back twice in the second half from going a goal down to earn a last-gasp point to end 2019.
Jake Young's 93rd minute curling effort was the least the Blades deserved for their efforts after going down to 10 men and having three debutants at said level on the pitch at the end of the game.
The first half was a more than quiet affair as neither side really did a huge amount to test the other team's goalkeeper, but 16-year-old Theo Williams was lively down the right on his Under 23s debut.
Just as it looked like the game would go in at the break all square, the visitors capitalised, nicking the ball back in midfield, breaking with pace and while it looked as though George Broadbent may have done enough to clear an effort from Baningime off the line after Michael Verrips got a hand to it, the linesman flagged to signal a goal.
The Blades forced a half chance immediately after when Jean Belehouan bundled an effort into the arms of the goalkeeper from a set-piece, the centre-back withdrawn at half-time through injury and replaced by second Under 23s debutant Harvey Cullinan.
If it was the last kick of the game that saved them a point, it was one of the first of the second half that sparked the match into life.
Tashae Andall-Gibbons closed down the Wigan goalkeeper and did enough to ensure the clearance was smashed against his leg, the ball fortuitously rolling into the back of the net to make it 1-1.
But Wigan were back ahead almost as soon as United had got themselves back into it. Wigan capitalised on another bit of loose defending and this time it was Adeeko who slammed home a cross from close range.
Verrips pulled off an outstanding save moments later to keep the Blades in the game and as the hosts looked for a late equaliser, third debutant Ryan Viggars was sent on up front alongside Young.
The task was made harder with five minutes to go when Harrison Foulstone saw red for bringing down a Wigan attacker on the edge of the box, though it appeared there were defenders covering.
Young had a big chance before the game moved into stoppage time when he headed Williams's cross just wide when he should have scored, but he made up for it with literally the final kick as he cut inside and unleashed an unstoppable curling effort to steal a point at the death for the Blades.
