A Shaun Harrad penalty was the difference as Rotherham defeated Accrington at the Don Valley Stadium.
Rotherham had plenty of early chances as Alex Revell headed just over and Kieron Cadogan had an effort saved with the hosts looking to be on top.
And following Bryan Hughes's foul on Mark Bradley, Harrad stepped up to give the Millers the lead with a penalty.
Stanley came closest when Danny Coid smash his effort over the bar, and the hosts held on for the points.
VIEWS FROM THE DRESSING ROOM
Rotherham United manager Andy Scott tells BBC Radio Sheffield:
"It was a big test for us tonight, because we haven't done too well at home and after the result on Friday everyone was looking at us to see if we could back it up.
"We won the game, got a clean sheet, another solid performance and I don't think they've had a shot on our goal.
"We created a few chances particularly in the first half and their keeper has made a fantastic save in the second half from Shaun [Harrad], so we were comfortable, but when it's 1-0 you're still a bit wary knowing what has happened to us in recent times.
"There's a belief that we can do it. The basis is hard work and organisation and we've said that since the start of the season. I think now it's coming to fruition."
