Airdrie United leapfrogged their hosts with a win over Peterhead with Allan Russell scoring the decisive goal.
The goal came in the 36th minute when Paul Lovering swept over a cross from the left wing and Russell met it to head into the bottom corner.
Peterhead will feel they were worth a point as they created plenty of chances but failed to capitalise.
Substitute Martin Bavidge broke clear in the 63rd minute but the shot flashed past the right-hand post.
