Stevie May scored twice on his home debut as Aberdeen edged past a dogged Dundee at Pittodrie.
May headed Greg Tansey’s corner past goalkeeper Scott Bain for his first.
Marcus Haber headed off the crossbar for Dundee before Roarie Deacon equalised when he intercepted Ryan Christie’s poor pass and drilled the ball into the net.
The Dons re-took the lead when Graeme Shinnie’s shot rebounded to May, who rifled in a second.
It means Aberdeen are one of three teams – along with Celtic and St Johnstone – to boast a 100% start to the season.
