Bingham on song again with second half winner after Andres put Latics ahead in first half.
WIGAN ATHLETIC UNDER 21s
SHEFFIELD UNITED UNDER 21s
A fifth goal in four games for Rakish Bingham with 13 minutes remaining puts Latics back on winning ways at Robin Park Arena after Aaron Barry tapped home a Blades equaliser early in the second half, following an early Guillermo Andres opener.
Graham Barrow made four changes from last week's 2-1 defeat to Sheffield Wednesday at the DW Stadium, with goal scorer Andres, Josh Sumner, Jesjua Angoy and Under 18 centre back Michael Wilson brought in to start.
Latics made a superb start to the game and the pressure put on Sheffield United's defence in the opening minutes forced two corners and a fourth minute goal.
The chance looked like a lost cause for Spanish striker Andres who was crowded towards the back of the box but as he faked going towards the by-line and cut the ball back onto his left foot, he simply picked his spot in the far top corner and curled the ball past a hapless Martin Dewbury in the visitors' goal.
For the first 45 minutes Latics pressed their opponents when out of possession and when the hosts had the ball they knocked it around with ease until an opening cropped up.
Half chances were created as the game edged towards half time and a single goal lead was always going to be a nervy one.
Despite a solid performance in the first half, the majority of the action came in the second.
Unfortunately for Latics the first piece of action ended up with Sheffield United equalising.
Just four minutes into the second half Elliott Whitehouse whipped a free kick into Latics' area from the right, forcing Marko Marosi to parry the ball on his line and it popped up to Aaron Barry who tucked the ball into the corner from close range.
Marosi brushed himself off after that and turned in an outstanding performance with a stretching save from Jahmal Smith's effort and a brilliant catch from a mid-height Ben Whiteman drive.
The goalkeeping display was just one of many highlights for Latics during the afternoon, with three Under 18 players Luke Ainscough, Joey Johnson and Ryan Meadows coming on in the second half and making their presence known.
Midway through the second half Latics picked their momentum back up and started to flow forward in their usual fashion.
On 67 minutes a foul on Josh Sumner on the edge of the area gave Captain Danny Redmond the perfect chance to equalise and he thought he had done as he curled to ball over the wall only for it to coming crashing down off the cross bar.
When Latics have upped the pressure this season they have generally scored and 10 minutes later in un-typically Latics fashion they found themselves ahead with a route one goal.
The 18-year-old midfielder Meadows continued to show quality as he spotted the run of Bingham down the middle and glided his pass over the defence from deep into his own half sending the striker on his way.
Bingham had two defenders breathing down his neck but remained cool, calm and collected even with Dewbury rushing out of his goal to challenge.
The 19-year-old saw him coming and delicately slide the ball around the keeper and into the bottom corner for 2-1.
With 13 minutes left to defend the narrow lead, it was left to midfielders Meadows and Ainscough to provide moments of inspiration in defence.
First Meadows used his intelligence to head the ball back to his keeper despite being under pressure from a free kick aimed at the back post and then Ainscough made a last ditch tackle inside the area, preventing Otis Khan from advancing on goal.
Latics had to see out four minutes of added time and did so with desire to grab their first league victory since the end of January.
