A three-goal blitz in 18 second-half minutes gave Clyde a deserved 3-1 victory over struggling Airdrie.
After dominating the opening period, the visitors went behind to an Austin McCann penalty after 36 minutes.
The spot-kick was awarded after David Fernandez - who was later sent-off for two bookable offences - had turned the defence on the halfway line and homed in on goal before being felled by Clyde keeper Bryn Halliwell.
Five minutes after the break, Chris Aitken levelled before Frenchman Frederick Bonniface was quickest to react to a loose ball inside the six yard box to put Clyde ahead.
And the match was all over for the Diamonds when Andy Kane tucked the ball past home goalkeeper Javier Sanchez Broto following good build-up play by Jack Ross.
