Ched Evans hit the only goal as Sheffield United stretched their unbeaten home record to six games with a 1-0 win against Carlisle United.
Blades top scorer Evans struck his seventh goal of the season on 21 minutes, firing into the roof of the net at the far post after Lee Williamson's corner was headed on.
Keeper Adam Collin had already turned a Williamson shot onto the upright.
And Collin then saved Richard Cresswell's poor 70th minute penalty.
The Blades' spot-kick was awarded after Ryan Flynn was fouled in the area by Christian Ribeiro.
The Cumbrians' third league game without a win (and their second without a goal) leaves them 11th in League One, six places - and six points - behind the Blades.
VIEWS FROM THE DRESSING ROOM
Sheffield United boss Danny Wilson told BBC Radio Sheffield:
"It was a great three points. It's always nice to keep a clean sheet and come away with the win.
"It was a hard earned victory for us particularly in the latter stages of the game, when they had nothing to lose.
"But we stood firm and we fully deserved the result."
Carlisle United manager Greg Abbott told BBC Radio Cumbria:
"I have just seen a dressing room that has put in a shift and got nothing for it.
"I have just seen 1,500 fans sing their hearts out and they have gone away with nothing to show for.
"Hopefully they have seen encouragement in the way the players are playing in terms of their determination."
