Jonathan Awofesobi, the 16-year-old left-back, made his debut for the under-19s as Stags won 1-0 at Stockport in the Youth Alliance Cup on Saturday.
Louie Turner returned in between the sticks for the amber and blue following his work experience loan at Heanor Town.
Sam Collins' side showed grit and determination to see out their cup fixture against the Hatters after taking an early lead courtesy of a goal from striker McKeal Abdullah.
Ten minutes into the game, young Stags' attacker Jakub Kruszynski made a run down the right-wing and managed to pick out his teammate Abdullah at the far post with a cross that was drilled across the area requiring the slightest of touches to break the deadlock.
The hosts' frustrations mounted in the opening stages, leading to several fouls which gave Mansfield a number of opportunities to double the lead.
On the half-hour mark, Abdullah cut onto his left-foot from the right-hand flank and his effort smashed against the post.
The second-half was similar to the first as Mansfield continued to create a number of opportunities.
Stags' first substitution of the game saw a change in the forward line as Louis Bonser replaced Ronnie Kokkinos.
The under-19s caused Stockport problems at corners and the ball fell to Stags' defender Cormac Maher on more than one occasion midway through the second-half but both efforts went wide of Daniel Harrison's post.
Mansfield right-back Taylor Anderson was replaced on 75 minutes by Lewis Warnaby.
Goalscorer McKeal Abdullah was also substituted seven minutes later as forward Noah Aynsley-Johnson came off the bench for the young Stags.
The latter stages of the game saw the visitors win a succession of free-kicks which allowed them to keep control of the match and with five minutes left to play, Kruszynski had a brilliant chance to double Stags' lead.
Substitute Bonser threaded a brilliant ball through the Stockport defence but Kruszynski's powerful effort was saved by the Hatters 'keeper.
