United are now nine games unbeaten in the Professional Development League, following Monday's impressive victory over leaders Huddersfield Town at Bramall Lane.
Goals from Ben Whiteman and Harrison McGahey help the Blades end Town's 16-match unbeaten run, as United's youngsters made it nine league matches unbeaten in the process.
United were positive from the first whistle and had a couple of opportunities inside the opening 15 minutes, Wright had a shot saved from Allinson after Horsfall failed to clear his lines, before Whiteman header over from Reed's free-kick.
Given the Blades early dominance, it was no surprise when the hosts eventually made their pressure count. Town failed to deal with McFadzean's deep left-wing cross and after Toner had blocked Adams's effort, McGahey recycled the ball for WHITEMAN to score from 12 yards out.
The home side were clearly in the ascendency and could have made it two when Reed caught Wilkinson in possession high up the field, but the midfielder's shot was blocked by the retreating Senior.
On the half hour both sides had clear sights of goal in quick succession. Firstly, for the visitors, Boyle saw his effort saved by Ramsdale having caught McGahey napping on the halfway line, then at the other end, Wright just failed to connect with a cross from Adams, following a through ball Reed.
As half-time approached the game opened up, Town had appeals for a penalty waved away as they claimed a handball by Kelly, before Adams stung the palms of Allinson, having controlled the ball and hit a goal bound half volley in one movement.
With the final action of the first period,
Huddersfield came within inches of restoring parity with only the crossbar saving the Blades as Holmes left Ramsdale stranded with a dipping long range effort, but the woodwork saved United and Kennedy cleared.
Huddersfield started the second-half brightly, but were almost caught on the break following a corner. Ramsdale fired a kick forward, Adams outmuscled Hanson before teeing up Reed but his tame effort was comfortably saved by Allinson.
Wright who had been limping for much of the first-half eventually admitted defeat and was replaced by youngster Hall and the substitute almost made an immediate impact, shooting narrowly wide after excellent work by the marauding McFadzean.
As the game continued to ebb and flow, the home side could double their lead, but after good work on the left, Hall just failed to connect with the goal at his mercy, but with 17 minutes remaining the hosts did get a second. Kennedy was denied twice by Allinson, but it was third time lucky as MCGAHEY bundled the ball home from close range.
United had wrestled back control of the game and Reed and McFadzean both tried their luck from range as the home side looked for a game clinching third, whilst for the Terriers, Holmes came close again.
But it mattered not as the home side comfortably saw out the remaining minutes without any scares, to net a deserved three points and clean sheet.
