The gap at the top of the Scottish Premiership is down to four points after Aberdeen drew closer to leaders Celtic with a comfortable 2-0 win at Dundee.
Niall McGinn’s fifth goal of the campaign and an Adam Rooney goal, which took his tally to 11, was enough to give the Dons all three points at Dens Park.
Dons manager Derek McInnes made one change to the side which beat Ross County with Ash Taylor restored to the starting line-up in place of Paul Quinn.
Fit again captain Ryan Jack was named among the substitutes while Dundee manager Paul Hartley named an unchanged 11 following the draw with St Johnstone last week.
The Dons were eager to build on their 3-1 win against Ross County last week and they did just that with two goals in the opening 25 minutes at Dens Park.
Niall McGinn opened the scoring in the 10th minute, capitalising on a clever flick from Ash Taylor from a Jonny Hayes corner, running on to the loose ball before firing past Scott Bain from 14 yards.
It went from bad to worse for the Dark Blues as Kenny McLean robbed Paul McGowan before playing in Hayes and his first time cross was sidefooted home by Adam Rooney.
The lightning start from Aberdeen left Dundee reeling and they struggled to impose themselves in the game as the Dons pushed for a third before the interval but Dundee held out to be only two goals down at the break.
Peter Pawlett replaced the excellent McGinn for the second half and he created a chance for a third when his shot was parried by Bain but McLean scooped the rebound over the bar.
Pawlett also fired wide and saw a shot saved by Bain as the Dons ended the game as they started it, carrying an attacking threat, but they had to settle for their two first half goals.
