BobDavidson's double preserved Dundee's 100% record as they beat a poor Queen of the South side. Davidson scored from the penalty spot after 13 minutes following Andy Aitken's needless shove on Jan Zemlik. Queens goalkeeper Jamie MacDonald twice denied Scott Robertson and had a tremendous save from a Zemlik effort. Sean O'Connor headed the equaliser from an Eric Paton cross - but, after a Paul Dixon attempt struck a post, Davidson steered home from Gavin Swankie's chip. A great week for the dark blues. They were not at their best yesterday, but last season they would have dropped points. So a good start and sets up the trip to Perth next week. St.Johnstone drew 2-2 and Dunfermline and Livingston both lost yesterday.
