Thame United caused a major upset in the Evo-Stik South East to trip up Beaconsfield Town’s promotion charge.
The mid-table Oxfordshire side came away from Holloways Park with all three points after a dogged display to dig out a 1-0 win.
It was a game that reserved all of its action for a tense second half after a largely uneventful opening 45 minutes.
Thame’s breakthrough came courtesy of Lynton Goss who tucked away the rebound from his missed penalty on 65 minutes.
A trip on Goss in the box after a through ball from Tom Ashworth left the referee with no option but to point to the spot.
Goalkeeper Ravan Constable guessed the right way but could only parry the ball directly back towards Goss who slotted it into an open goal.
The away side finished the stronger as Beaconsfield were reduced to 10 men after Alexander Cathline was given his marching orders for an elbow to the jaw of Adam Morris.
An organised team performance saw out the game to move Thame to 10th in the division on 42 points.
They are nine points off the play-offs with games in hand on most teams.
Thame move on to prepare for the visit of third-bottom Hanwell Town on Saturday.
