Four quickfire goals just after the hour mark lifted Pinchbeck United above Langtoft United into fifth place in the Peterborough & District League’s Premier Division.
The Vikings were left feeling shell-shocked after allowing a game they were in control of to rapidly get away from them.
They had been leading 1-0, and missed chances to make it 2-0, before the points were torn from their grip.
Langtoft took the lead through Josh Hales’ penalty in the first half. Having been tripped inside the area, the forward picked himself up and sent the spot-kick down the middle of the goal.
Tony Wooding wasted a chance to double the lead, Dan Evans’ penalty appeal was turned down and Hales’ effort was cleared off the line.
Pinchbeck hit back to win 4-1 through Tom Gosling, Oliver Maltby, player-boss Ian Dunn and fellow substitute Ashley Murrell.
Langtoft manager Phil Gadsby said: “I’m a bit shell-shocked as to how we managed to lose a game we were in control of for 60 minutes.
“That is the most disappointed I’ve been in my team since I took over as manager. We completely changed our style of play for some reason and it cost us.
“I think naivety is probably the best way to describe it, and too many people went hiding when they needed to stand up and be counted.”
Crowland Town are back at the foot of the table after a 1-1 draw with Holbeach United Reserves.
