Chris Porter's late header sent Sheffield United into the npower League One play-off final after a tense 1-0 semi-final victory over Stevenage.
After a goalless first leg and a similarly even first 85 minutes at Bramall Lane, extra-time looked on the cards until Porter popped up at the back post to nod Matt Lowton's pinpoint cross past Chris Day.
It sent the home fans wild and was a moment of personal glory for Porter, who had struggled in a lone role up front.
The win was nothing less than United deserved, though, as they were the dominant force throughout and it should have been a more resounding victory, but Ryan Flynn, Lee Williamson and Stephen Quinn were all denied.
As it was, Porter's goal was enough to secure passage to Wembley where Danny Wilson's side will meet either Huddersfield or MK Dons, who play the second leg of their semi-final on Tuesday night.
