United's Under 23s bounced back from two consecutive defeats with an excellent performance to record a comfortable victory at home to Bolton.
A brace from Oli Greaves and strikes from Conor Washington, the striker getting an hour under his belt at Stocksbridge, and Reece York was enough to see the Blades home in full control of the match.
United were on the front foot from the off in a confident performance and Greaves was a menace from the opening minutes when his floated cross had to be pushed away by James Aspinall.
Keenan Ferguson saw a teasing cross turned behind and Greaves saw another effort saved inside the first five minutes alone before Greaves neatly turned the ball home from a corner to put United in front.
Bolton's best opening came minutes later when Marcus Dewhurst was forced to make a flying save but in reality, that was as close as it came to the points being under threat.
Within 20 minutes it was 2-0 when York did well to intercept Aspinall's poor kick out, slotting in Washington who jinked past his man and fired home with his left foot.
United had their third and Greaves his second after half an hour, the lively forward cutting in from the right and sending an effort low past Aspinall to put the result to bed.
The second half was much quieter with United happy to sit on their lead and Bolton failing to create enough to worry Dewhurst.
A triple sub saw Jean Belehouan, Zak Brunt and Sam Ackroyd all introduced with 25 minutes to go, and it was the latter who did well to set up York for United's fourth.
Some nice play out on the left allowed Ackroyd to find York inside the box, the midfielder firing home with his left foot after Aspinall could only do enough to send the ball onto the far post and in.
It could have been five with 10 minutes to go when Sheppeard took advantage of Aspinall coming out of goal to find Ackroyd, the striker seeing his effort turned in by Belehouan, unfortunately the offside flag denying him a goal.
