The Iron's youth team defeated their Grimsby Town counterparts 4-0 on Saturday.United were away for the second time in a week when they travelled to the Cheapside training ground of Grimsby Town.
The Mariners could have opened the scoring on four minutes when Iron goalkeeper Ben Ledger miskicked his clearance straight to the home team's striker but Ledger made amends by making the save.
Leslie Sackey was through on nine minutes but the Town goalkeeper beat him to the ball to clear the danger.
United should have taken the lead on 12 minutes when Jack Dyche's shot was deflected into the path of Sackey but his effort was scrambled off the line and behind for a corner.
Shortly after, Dyche was threatening again but lost possession when he cut back inside to shoot.
The Iron made the breakthrough, which had looked like it was coming, and it was Dyche on 25 minutes who fired the visitors in front after good work from Sackey.
On the half hour mark Ledger had to make a point blank save after a free kick was deflected into the path of a Mariners player.
Eight minutes before half-time and the Iron extended their lead as they went 2-0 up with some excellent play. It was Dyche who slotted home after Sackey had split the Mariners defence with an excellent throughball.
On 39 minutes, Sackey made it 3-0 when a James Dean-Atkinson corner was turned home, and the frontman scored his third goal in two games.
On 49 minutes, the Iron put the game beyond doubt when they made it 4-0. An excellent diagonal ball from Watkiss found Sami Ebraheem who drove into the Grimsby penalty area before picking out Dyche who made no mistake to notch his third goal of the game.
After the match, academy manager Tony Daws said: "As a team, our boys were excellent. We were a threat every time that we attacked but for me the most pleasing thing was that we kept a clean sheet and this is what we have worked hard to earn all week. Well done to the lads."
