Derek McInnes reckons Kilmarnock showed they have what it takes to compete in the Premiership as they put St Johnstone to the sword.
A Dan Armstrong double with goals either side of half-time ensured it was the Ayrshire side celebrating, despite a nervy end when Theo Bair scored a stoppage-time consolation.
The result means Killie leapfrogged Ross County into 10th place, leaving themselves just three points behind St Johnstone in ninth.
