Staveley Miners Welfare completed a derby double over nine-man Retford United in a fierce encounter at Inkersall Road on Wednesday night.
Two goals from Josh Scully and one from Matt Thorpe secured three points for the home side who also had caretaker manager James Colliver sent off.
The win for Staveley made it three unbeaten and back-to-back victories.
It also meant the Welfare had beaten Retford twice within the space of a month after winning 4-1 away in January.
Colliver opted to make one change from the team that won 5-3 at Liversedge with Wes Hill replacing Pat Lindley.
The Badgers started the game lively in the opening exchanges but it was Staveley who took the lead on 13 minutes.
Winger, Matt Trench, left full-back Gav Cooper in his trail and his cross was only half-cleared to Scully who found the top corner from 25-yards.
Three minutes later, the away side were down to ten men.
Cooper was shown a red card for an off-the-ball incident on Trench, leaving Retford with an uphill task to get back into the game.
It wasn’t long before referee Sam Mulhall was reaching for his back pocket again.
Retford’s Jake Stannard seemed to have a clear path to goal but he was brought down by last-man Colliver and was shown red.
The action-packed first-half showed no signs of settling down and a mistake by Danny Smith allowed Staveley to double their lead on the half-time whistle.
Matt Thorpe took full advantage by rounding goalkeeper Jody Barford to slot home.
The second-half started with a couple of half-chances for Staveley and Thompson was set to pull the trigger at the other but for a great block by Matt Hassett.
On 65 minutes, Retford had a lifeline. Captain Craig Fisher stroked the ball past Tom Turner from ten yards to reduce the deficit.
Retford huffed and puffed for the equaliser but then came the third sending off.
Barford came rushing off his line and brought down Jamie Smith in the penalty box as the visitors were reduced to nine men.
Retford midfielder Tom Dorgan had earlier moved to full-back to cover the red card of Cooper and now he found himself in goal.
Scully scored the penalty to claim his second of the game. Away substitute Jack Booth pulled another back in injury-time but Staveley held on.
