Damian Reeves' second-half strike gave Altrincham a famous FA Cup victory as they picked up a 1-0 win over League One side Barnsley at Moss Lane.
The striker's goal came minutes after the interval for the National League side with both teams having first-half penalty appeals turned down.
Barnsley dominated the game in large spells but were made to pay for missing numerous gilt-edged chances.
In what proved to be their first meeting, both sides shared early chances in a combative opening 45 minutes.
In the 18th minute Ryan Crowther's cross struck Marc Roberts on the arm but the referee took no interest as appeals were waved away.
Barnsley had their own claim turned down eight minutes later when a challenge on Sam Winnall was deemed fair.
Winnall had another chance with two minutes remaining in the first half but saw his effort well saved by Tim Deasy.
Altrincham were ahead in the 47th minute when Adam Davies could only palm Crowther's drive into the path of the oncoming Reeves.
Barnsley went on to dominate possession, with substitutes Lloyd Isgrove, Conor Wilkinson and Conor Hourihane all coming close to scoring.
But, despite extended pressure on their goal, Lee Sinnott's men were resilient and held out for the win.
