Dundee are still winless in 2020.
Despite taking an early lead through Kane Hemmings and playing the last half hour of the match against 10 men, the Dark Blues could only draw with Morton.
That makes it five games without a victory and other results meant they are now out of the play-off places.
Dundee couldn’t have asked for a better start as they were a goal up after just 12 minutes.
Deadline day signing Christophe Berra picked out Hemmings in the box and it was classic number nine play from the Englishman to roll his marker, Sean McGinty, and then lash a finish high past the helpless Danny Rogers.
The equaliser came midway through the first half when Conor Hazard didn’t get a strong enough hand to a deflected Nicky Cadden free-kick and could only put it on a plate for Jim McAlister to tap in the rebound.
There was a big shout for offside against the scorer but the assistant referee kept his flag down and the goal stood.
It then turned into a half of two halves, with the flow of the game changing completely.
Kalvin Orsi won’t score with many overhead kicks but after he did just that the effort was (correctly) chalked off for offside.
The same man missed a great chance seven minutes after the break and in the subsequent goalmouth scramble Jordon Forster nearly scored an own goal.
Just before the hour Morton were reduced to 10 men when Kyle Jacobs got a second yellow card for a crude tackle on Hemmings on the half-way line.
That had an immediate effect on the match, with Jordan McGhee seeing a 20-yard volley tipped over seconds later. From the corner Declan McDaid hit the post and Forster headed the rebound wide.
An Orsi glancing header and a stoppage time deflected Christie Elliott free-kick were the closest the teams came to a late winner and the fact that Dundee didn’t make their numerical advantage count will be a huge source of frustration for their manager.
