Aberdeen stretched their unbeaten league run to 13 league matches and increased the pressure on champions Celtic with a composed and comfortable win at home to toothless St Mirren.
Adam Rooney was the difference maker for the Dons, netting on 21 minutes after a sustained spell of pressure, and then again just two minutes after the interval.
Victory was earned at a canter for the Dons who were easily able to draw the sting from St Mirren’s occasional attacks with ease while always looking capable of scoring more.
The third goal came on 65 minutes, as simple as they come when Niall McGinn’s deep corner from the left was met by the unmarked Mark Reynolds who powered in a header past goalkeeper Mark Ridgers.
Ole football at the end of the Dons, who travel to Celtic on Sunday for a match which will define the season.
