Nade on target for Dee
Christian Nade scored his first goal for the Dundee as the leaders beat struggling Morton 2-0.
The hosts drew first blood in the 13th minute when forward Nade got on the end of Martin Boyle's cross to head in.
Dundee continued to ask questions of the league's basement club in the first half, but they could not find a way past Derek Gaston.
However, Peter MacDonald doubled the Dark Blues' lead four minutes before the end when he drilled the ball past Gaston from the middle of the box.
