Alloa Athletic 0-1 Dundee
Peter MacDonald's second-half goal gave Dundee victory over Alloa Athletic and moved John Brown's side top of the Scottish Championship.
The visitors made a strong start to the game but Alloa defended well before themselves having a concerted period of pressure.
MacDonald got on the end of Martin Boyle's cross to head home.
Dundee were then reduced to 10 men after Iain Davidson saw red for violent conduct but their lead remained intact.
