Gary Mackay-Steven’s penalty was enough to give Aberdeen all three points against Dundee at Dens Park.
Dundee’s Josh Meekings failed to connect with a cross when he had the goal gaping, while Aberdeen’s Bruce Anderson volleyed off the crossbar.
Genseric Kusunga conceded the spot-kick when Dominic Ball’s header hit his arm, and Mackay-Steven sent Dundee goalkeeper Jack Hamilton the wrong way.
The hosts had chances and Adil Nabi forced a fine save from inside the box.
Neil McCann’s side put plenty into the game, but it is two defeats out of two for them so far in the Premiership, while Aberdeen earned their first league win after last week’s home draw with Rangers.
