Kilmarnock picked up a vital win on the road tonight meaning they require just one point at home to Ross County to stay up on survival Sunday.
A Kyle Vassell double before Innes Cameron's late strike ensured it was a comfortable 3-0 win away to Dundee United.
Had St Johnstone held on to their two-goal lead in Dingwall the Ayrshire side would already be safe, but a fightback from the Staggies ensures it goes down to the wire on Sunday at Rugby Park.
