Justin Richards struck his sixth goal in five matches to give Burton Albion victory over Crewe Alexandra.
Alex keeper Steve Phillips had to be alert early on to make a full-length save from a John McGrath effort.
Burton then made the breakthrough when Richards beat Phillips in the race to Aaron Webster's pass, before finding the net past the covering defenders.
Matt Tootle had the visitors' best chance but he saw his shot saved by the legs of Burton keeper Ross Atkins.
VIEWS FROM THE DRESSING ROOM
Burton manager Paul Peschisolido told BBC Radio Derby:
"All you need to do is beat the opposition by one but I thought we were magnificent today, absolutely magnificent.
"I was pleased we got the clean sheet. The challenge was there for the boys.
"After a lacklustre defending performance against Oxford I could have been rash and taken them all out but I wanted to give them the chance again and they've come up trumps.
"That's how you win games, you keep clean sheets."
Crewe Alexandra manager Dario Gradi told BBC Radio Stoke:
"Steve [Phillips] has apologised but we owe him because he's made some super saves to keep us in it.
"If that incident hadn't have happened, we might have got a good point or even got a win.
"I thought we played better than them in the second half but without creating a lot of chances."
