United's youngsters made it two wins in a week, with a deserved Yorkshire derby victory over Leeds United at the Steel Phalt Academy on Saturday.
Goals from Brodie Litchfield and Joseph Cummings settled the contest in United's favours, four days after the Blades had safely progressed to the second round of the FA Youth Cup.
The Blades started positively with Mallon and Smith combining well on a number of occasions down the left, but unfortunately the hosts failed to make that dominance count in the opening exchanges.
On the half hour, Leeds should have been in front, but for the brilliance of Ramsdale, who saved his third penalty of the week, having saved two in the FA Youth Cup shootout victory over Bradford City, after Adebowale had been penalised for a mistimed tackle.
Within five minutes, United had made the most of that let off, as LITCHFIELD lost his marker to convert from Hallam's inviting centre to send the Blades into the break with a one-goal advantage.
The home side replicated the positive start of the first period and were rewarded further on the hour when CUMMINGS headed home superbly from Gordon's pinpoint cross from the right.
Leeds threw caution to the wind in a bid to mount a revival, but in truth the Blades comfortably saw the game out and could have won by a greater margin had substitute Tyler Smith scored from Burton's ball into the box.
But the victory saw the Blades record a fifth home win from six outings at Shirecliffe.
Blades: Ramsdale, Charlesworth, Semple, Adebowale, Cummings, K. Smith (Maw 66), Gilmour, Gordon, Mallon, Hallam (T. Smith 71), Litchfield (Burton 79).
Unused: Perryman, Ford.
