Dark Blues battle back
Goals from Gavin Rae and Ryan Conroy either side of half-time cancelled out an early strike by Andrew Jackson.
The home side stormed into a fifth-minute lead when Jackson slotted in from close range after good work from Paul Di Giacomo.
But just as Morton looked to be heading into the break in the lead, Dundee equalised through midfielder Rae who finished confidently after being set up in the box by Ryan Conroy.
After the restart the away side looked to take the initiative and were duly rewarded when the dangerous Conroy found the net with a sweet left-footed finish from close range with 56 minutes gone.
