Swindon scored a last-gasp winner to see off high-flying Huddersfield 1-0.
Having dominated the game Shaun Morrison popped up to head in Alan Sheehan's corner in stoppage time to win it.
The Robins were the only team in it for the vast majority of the game, but looked like being stifled by Lee Clark's men.
And they could easily have been behind as early as the sixth minute, when after a poor clearance, goalkeeper David Lucas kept out Jordan Rhodes with his legs.
Danny Wilson's Swindon dominated from then on and saw quick-fire chances for Morrison and Kevin Amankwaah come and go in the first half.
Fans were cheering 30 seconds into the second half when Thomas Dossevi's 25-yard effort looked to be heading in but went just wide.
Dossevi and the impressive Vincent Pericard saw their shots blocked as the game entered its final third, while another miss by Pericard was greeted by groans by the Reds' faithful.
But just as time looked to be running out, up rose defender Morrison to head into the bottom corner to raise the roof at the County Ground.
