Aberdeen moved to within two points of second-placed The Rangers with a game in hand after a comfortable Scottish Premiership win over struggling Dundee.
A-Jay Leitch-Smith had an early opportunity for Dundee, but goalkeeper Freddie Woodman saved well.
The Dons edged in front when goalkeeper Elliot Parish failed to deal with a Ryan Christie cross and Graeme Shinnie finished into the unguarded net.
It was all Aberdeen after the break, but one goal was enough.
The Dons’ ninth straight win over Dundee means they have not lost to the visitors in 11 meetings since November 2014.
