Luke O'Neill fired Mansfield to their first away win of the Blue Square Bet Premier season at Stockport.
O'Neill grabbed the solitary goal when he linked up well with Matthew Green before driving a low left foot shot past Matthew Glennon.
That was a rare highlight in a game of few chances which saw Stockport suffer their first defeat of the season.
Before O'Neill's goal Ross Dyer wasted a chance for Mansfield when he headed wide from six yards out.
