In only the third ever match between the two clubs, chances were few and far between in a drab first-half, reflecting the previous two encounters which both ended in uninspiring draws. Ayr's Ryan Stevenson came closest in the first half when his free-kick struck the crossbar.
United opened the scoring in the 54th minute when Jerome Vareille's cross was headed home by substitute Paul McLeod and United's top scorer Ryan Stevenson sealed victory with 20 minutes remaining with a traditionally cool finish making it third time lucky for Ayr.
League position kept the two United's of Ayr and Airdrie apart until they did finally find themselves as league buddies in Division Two in season 2007/08.
The two clubs met for the first time at New Broomfield Park on 6th October 2007 where the clubs served up an uninspired 0-0 draw in front of 1,269 people. Airdrie United's first ever visit to Somerset park was on 27th February 2008 when another draw - this time 1-1 was recorded in front of 1,104.
Last night only 737 fans turned up to see Ayr United break this run of draws and record their first ever win against Airdrie United.
