Ian Thomas-Moore scored a hat-trick as managerless Rotherham thrashed Lincoln.
The Millers were given the lead when Thomas-Moore, the son of ex-boss Ronnie Moore, finished from close range.
Danny Harrison then struck from distance before Thomas-Moore found the top corner and Ryan Taylor thumped in the fourth from inside the box.
Thomas-Moore got his third from the spot as Patrick Kanyuka saw red for a second booking, before Jason Taylor completed the rout from 25 yards.
Rotherham striker Ian Thomas-Moore told BBC Radio Sheffield:
"It has been difficult to say the least, but today it's gone well for me.
"I spoke to him last night (former manager Ronnie Moore) and he said it's guaranteed that you'll win and you'll score the first goal
"It was a big decision for Andy coming in and leaving Alfie (Adam Le Fondre) out."
Lincoln City manager Steve Tilson told BBC Lincolnshire:
"They didn't earn the right to score six goals, we've gifted them four or five. We certainly need to buck our ideas up in the last eight games because that was nowhere near good enough.
"The difference between the sides was that it looked like Rotherham had something to play for and we hadn't, but we're not there yet, not by a long way.
"I've got to get some leaders in for next season, that's for sure, because we are so naive. I'll hold my hands up, I made a couple of changes that maybe I didn't need to, but they're pro footballers and they've got to be able to handle that and as a group of players we weren't good enough."
