Recap

Adam Rooney scored a hat-trick as Aberdeen maintained their unbeaten Premiership start with a comfortable win at home to St Johnstone.

The striker glanced in an early opener and added another header from close range on 18 minutes.

His third goal came from a second-half penalty after Ryan Christie was upended.

Frank Ross hit the post late on as the hosts dominated and the win takes them level on points with leaders Celtic.

This was only Rooney’s third start of the season but that’s no excuse for the St Johnstone seemingly forgetting just how dangerous the most prolific Aberdeen striker of recent times is.
