Queen of the South opened up a 20-point lead at the top of the Irn-Bru Scottish Second Division with a routine home win against Ayr United.
Daniel Carmichael should have put the hosts ahead in the 21st minute but his right-footed effort flashed wide from six yards out
Christopher Higgins went even closer four minutes later with a header that struck the upright.
The Doonhammers eventually made the breakthrough on the stroke of half time when Carmichael presented Derek Lyle with a simple close-range header.
Carmichael was involved again after half time, this time releasing Gavin Reilly who doubled the hosts' lead with a clinical left-footed strike on the hour mark as Allan Johnston's men made their dominance count.
Honest Men striker Mark Roberts tried an audacious lob six minutes later which drew a save from Lee Robinson but the runaway leaders were able to coast to their 11th win in 12 games.
