Luke McCowan sent an early effort straight at goalkeeper Aidan McAdams and then curled another attempt over the top.

McCowan fired another shot from a tight angle into the side-netting after bursting into the area before McAdams produced a fine save to keep out a Tom Walsh effort on the stroke of half-time.

The opening goal arrived in the 55th minute, Aaron Muirhead laying the ball off for Smith to steer his shot into the net.

And Ayr wrapped up victory three minutes from time as Smith finished off a fine break from Michael Moffat.
