Airdrie clinched the final spot in the Scottish Second Division play-off places despite being held to a goalless draw with champions Cowdenbeath at Central Park.
The Diamonds started the afternoon in fourth ahead of Stenhousemuir on goal difference and only had to match the Warriors' result to stay there.
Airdrie almost took the lead through Kieron Stallard after 22 minutes, but his 20-yard effort hit the crossbar.
Chances were few and far between in the second half as the two sides cancelled each other out, leaving the door open for Stenhousemuir.
But the point proved to be enough for Airdrie who will now face Ayr in the play-off semis, with the Warriors missing out having been defeated 2-1 by Forfar.
