Greg Wilkinson only touched the ball once in the Conference North play-off final but it was a touch that broke Guiseley hearts.
The Altrincham substitute had not been on the Moss Lane pitch more than 60 seconds when he scored in the final minute of extra-time to give his side a 2-1 victory.
And it was a goal that sent the Guiseley players – and their promotion hopes – crashing to the ground.
“As an instant cruel moment – when you see the ball rolling into the net – I have never had anything like that,” said Lions boss Mark Bower.
“It was – as a one off moment – as cruel as it gets, but we have to use that to bounce back. We have to remember the remarkable run of form we have been on to get into this position and we have to use the disappointment, the hurt and the pain.
“There are lads in the changing rooms who can’t get their kit off, can’t get in the shower because a whole season’s work has gone in injury-time of extra-time of the last game of the season.
“Everyone gets knocked down and the best ones get up.
“The game looked to be dying and heading for penalties and maybe we have switched off.
“There were two minutes to add on and we were encouraging the lads to see it through – unfortunately we have not managed to do that.”
Dangerman Damian Reeves hit the bar after just six minutes of the first half but Guiseley – beaten just once in the previous 20 games – finished the opening period of the game strongly with Alex Johnson firing narrowly over from 12 yards and Jake Lawlor having a header cleared off the line by former Lion James Walshaw.
A Danny Ellis effort early in the second half – from an Andy Holdsworth free kick – was well saved by home keeper Stuart Coburn.
But Altrincham broke the deadlock after 50 minutes when Walshaw was given the chance to lay the ball into the path of James Lawrie and he guided it home from eight yards.
Danny Forrest was thrown into the action and almost made an instant impact with a side-footed effort that went narrowly wide.
And he bagged a deserved equaliser with 21 minutes remaining as he guided the ball into the net after Lawlor had got his head to another Holdsworth delivery.
Chances were at a premium after that – Potts was denied for Guiseley and Steven Drench saved from Shaun Densmore – and the game went into extra-time. It was typically cagey, although Kyle Perry’s long-range effort did scrape the top of the Guiseley crossbar on its was over.
Then, with the penalty shoot-out looking inevitable, Drench came out to block Perry only for the ball to land at the feet of Wilkinson and he did the rest.
It was a crushing blow for everyone connected with the club, including the 794 away fans in a crowd of 4,632.
But Bower admitted he had felt worse when his side suffered a fifth successive league defeat on the same ground back in October.
“I think that was lower given that we seemed like we didn’t know where we were going,” he said.
“I am proud of the efforts that went in on Saturday and proud of the efforts of the last few months that got us into that position.
“I know we have decent foundation in place to go again next year. We were stood on this pitch in October having just been beaten 4-1 and were third bottom in the league. To get to where we got to is an achievement and the group of players in the changing room have done remarkably well to get us to this point.
“It’s difficult to know what to say to them. They are on the floor.
“You can only thank them for their efforts, it’s been fantastic.
