Airdrie survived a last-minute penalty claim as they came from behind for a deserved win over Raith Rovers in the first round of the CIS Insurance Cup.
Rovers' Michael Brown produced a fine diving save from Stephen McKenna's penalty before Armand One broke the deadlock with a 20-yard drive.
But fine passes from Graeme Holmes set Willie McLaren and Bryan Prunty free to round the goalkeeper and score.
However, Airdrie escaped when a hand seemed to be used in the final minute.
