Just six days after sacking manager Brian Laws, Scunthorpe surged into the Sky Bet League Two play-off places with a thumping 4-0 win at nine-man Rochdale.
Defender Niall Canavan scored five minutes before half-time and the remaining goals came in the final quarter-hour.
Sam Winnall to made it 2-0 from the spot, and Jimmy Spencer and David Syers added to the home side's misery following two red cards.
Caretaker boss Russ Wilcox has claimed he is "capable" of doing the job on a permanent basis and backed up his statement with a second consecutive win, following Saturday's 2-1 success over Portsmouth.
Scunthorpe chairman Peter Swann has dismissed rumours David O'Leary is in the running for the vacant manager's job at Glanford Park.
The Iron sacked Brian Laws last week following a five-game winless run, but responded under caretaker-bosses Russ Wilcox and Tony Daws with victory at Portsmouth on Saturday.
Swann and the board hope to draw up a short-list of candidates to succeed Laws this week.
"A big thank you to Russ and Tony for stepping in and steadying things, it can never be easy when a manager goes especially when you've worked with them for 14 years, so the professionalism shown towards the situation is warmly applauded,"
Swann told the club's official website. "With regards to the manager's position, I find myself once again repeating the fact that David O'Leary is not in contention, has not applied and has never met me.
"Please do not waste your money, if you're having a little gamble on the outcome, the bookies are the only winners.
"Applications are still coming in and we will begin looking at a shortlist over the coming week and I must say we have a lot to discuss as a board, so please give us time and we will find the best candidate for the job."
Scunthorpe United have sacked manager Brian Laws following last night's 2-1 home defeat to Grimsby Town in the FA Cup. Laws returned to Glanford Park last October for a second spell at the club. In his 52 games in charge since his comeback the Iron have won 17, drawn 14 and lost 21.
The club are currently 12th in League 2, but just 2 points off a play-off place. However last night's defeat to North Lincolnshire rivals Grimsby had the home fans chanting "you're getting sacked in the morning" and that appears to have sealed his fate.
Scunthorpe United registered their first home win since September with a 2-1 win against fellow League 1 strugglers Portsmouth. Akpo Sodje got both goals to lift the Iron out of the relegation zone.
Meanwhile Conference North side Gainsborough Trinity made it into thelast 4 of the FA Trophy with a 2-0 win over Barrow. They join Grimsby in the semis and possibly FC Halifax Town, who play Dartford in their quarter final replay tomorrow night.
