Dundee dropped off the top of the SPFL Championship table after going down 1-0 to Greenock Morton on Saturday in the Cappielow sunshine.
The home side survived long spells of pressure from a Dundee side who passed up golden chances in the second half for Peter MacDonald and Christian Nadé. As the game opened up Morton looked more dangerous and they grabbed the winner after 76 minutes from Dougie Imrie.
