United's U23s continued their rise up the Professional Development League with a comprehensive victory over Leeds at Shirecliffe on Friday afternoon.
After a goalless first-half, second-half goals from Tyler Smith, a penalty from Jake Wright and Jordan Hallam were more than enough to complete the double over the Championship outfit.
United had the first chance after what was an scrappy opening 20 minutes, as Wright headed at Peacock-Farrell from Reed's right-wing free-kick.
Gradually, despite Leeds offering a threat on the counter attack, United seized the initiative and forced several corners in quick succession.
The last meaningful action of the first period saw Cummings have an effort at the back post saved on the line from Peacock-Farrell after Hallam's corner wasn't cleared properly.
The second-half saw the Blades start positively and they deservedly took the lead just before the hour. Hallam intercepted a pass in his own half, advanced at the Leeds defence menacingly before slipping in Wright, who unselfishly squared to SMITH to tap home, having drawn Peacock-Farrell out of his goal.
And United quickly doubled their advantage, after the referee Wild adjudged trialist Bainbridge had been upended in the penalty area from Hallam's corner. From the spot, WRIGHT sent Peacock-Farrell the wrong way.
In the next attack, Smith was played in and looked destiny to get his second, only for Peacock-Farrell to deny him with an outstretched leg. The Blades were the dominant force in the game and Cummings should have made it three, but headed straight at Peacock-Farrell with the goal at his mercy.
But with seven minutes remaining, United did make the game safe, as HALLAM got a goal his performance deserved, slotting home confidently and that proved to be the last action of note.
Blades: Eastwood, Charlesworth, Cantrill (Mallon 56), Doherty, Cummings, Bainbridge, T. Smith, Reed, Wright (Parkhouse 86), Johnson (K. Smith 62), Hallam.
