Terry Gornell scored the winner as Stanley ended the 2014/15 season on a high.
There was little resting on the game between the 17th placed Reds and 21st placed Mansfield but, after a 4-0 defeat at Dagenham last week, boss John Coleman wanted a positive reaction from his side.
The first half was largely one to forget – especially for the Reds who trailed at the break.
Mansfield’s Jamie McGuire had a great chance to open the scoring on 10 minutes when he chipped the ball over keeper Scott Davies – however he only found the side netting.
Junior Brown had another go a minute later for the Stags but this time fired just wide.
From then on neither side created much before Mansfield, who had lost seven out of the previous eight matches, made a rare chance count on 39 minutes. Jamie McGuire got the ball on the edge of the area and he volleyed home his first goal of the campaign.
Stanley did almost equalise on the stroke of half-time from a corner but a Luke Joyce header was kicked off the line.
The Reds came out and meant business after the break and, on 47 minutes, Josh Windass’s initial header was saved before Seamus Conneely followed up and fired home his third goal of the season.
Stanley then upped the pressure with Terry Gornell firing over from 20 yards while Windass got the better of keeper Lenny Pidgeley at the by-line but there was no one to capitalise on his cross.
Windass also came close with a free kick which took a deflection just after the hour.
However, Stanley striker Gornell then raced down the left wing and put the ball past the outrushing Pidgeley to give the Reds the lead on 71 minutes.
Captain Joyce could have finished with a goal but headed over in injury-time.
