Paddy Reading struck a stunning late winner as Ayr United gained a storming Ayrshire derby win to drive a hole in the title hopes of their bitter rivals.
The full-back crashed home a low half-volley following a period of constant pressure as United gained a deserved three points for a brilliant second-half show.
And it piles more pressure on Kilmarnock, now five points behind leaders Arbroath, as their stuttering bid to return to the Premiership at the first attempt took another hit.
