The hosts took the lead on the quarter mark though a well-taken Reece Hales finish.
However, in a hectic 20 minute spell at the end of the first half, Blues somehow found themselves 3-1 behind.
But after regrouping at the break, Blues dominated the second-half and pulled a goal back after 67 minutes courtesy of Kwadno Asamoah’s miss-hit effort.
The same player then secured a share of the points for his side with a 94th minute overhead kick that found the back of the net.
Academy coach Steve Spooner felt it was one of his side’s best attacking displays of the season, although he was disappointed with the way they gifted Wigan three goals.
“Some of our football was excellent,” said Spooner.
“After taking the lead through Reece, some of our defending was suicidal and we allowed them to score three goals which they didn’t really have to work too hard for.
“We came back into in at 3-2, before Wigan had another great chance, which was well-saved by Callum Preston. Then in the 94th minute we scored the equaliser, which was no less than we deserved. It was a great ending but I would have been disappointed if we’d come away with nothing.
“For long periods of the game that was the best we had played attacking-wise this season and I lost count of the amount of chances we had. Overall I was very buoyed by the performance, but it was disappointing to concede three goals.”
