Defender Peter Grant headed home the only goal of the game in first-half stoppage time

Morton secured their first win in four matches to climb fourth in the Scottish Championship as Peter Grant's emphatic header was enough to beat Dundee.

Grant met Nicky Cadden's free-kick from the left for his second goal of the season on the stroke of half-time.

Dundee, for whom Graham Dorrans make his debut as a sub, fall to sixth.

James McPake's men created a couple of early chances through Paul McGowan and Declan McDaid, but were unable to build on last week's win over Alloa Athletic.

Morton assistant manager Anton McElhone: "Our team have got a great spirit that they can out-run and out-work the opposition, but they've got quality in there as well.

"The experienced players are leading from the front and helping the young players. At home we're happy, away from home we need a little bit more luck."

Dundee head coach James McPake: "I'm frustrated to lose in that manner. For 44 minutes we handled it and then a moment of madness - a silly free-kick and we lose our man and it costs us three points."
