Goals from Danny Philliskirk and skipper Terry Kennedy helped the Blades to an excellent victory over Birmingham City at Wast Hills on Tuesday afternoon.
Philliskirk opened the scoring early on and despite seeing Papa Bouba Diop equaliser for the hosts who also included Nikola Zigic and Darren Ambrose in their starting XI, Terry Kennedy netted the winner just after the hour mark from a corner.
With the first chance of note United took the lead in the 10th minute when PHILLISKIRK finished smartly from the edge of the area.
The hosts replied with Ambrose coming close to an equaliser on two occasions, before Zigic volleyed over after Henry-Francis had created an opportunity for the Serbian striker.
Kennedy almost deflected another Ambrose effort beyond Willis before making a timely intervention to deny Zigic a clear sight of goal.
Willis was then called upon to deny the powerful Diop, whilst at the other end, with the final action of the first half; Harriott came within a whisker of connecting with Philliskirk's low cross to double United's advantage.
In the 49th minute the home side drew level. DIOP headed home at the back post following Hancox's cross from the left.
Moments later, Henry-Francis took a tumble in the penalty area when contesting for a ball with Willis but the referee rebuffed City's appeals for a spot kick.
Parity wasn't restored for long though as the determined Blades seized the advantage from a set-piece, KENNEDY bundling the ball home from close range.
The visitors defended excellently as the second period progressed and only a shot from Henry-Francis came close to denying them a deserved success.
Blades: Willis, Hodder, T. Williams (Barry 69), Harriott, J. Williams, Kennedy, Tonne, Pemberton, Ironside, Philliskirk, De Girolamo (Smith 81).
