Dundee started well and they looked good going forward, Paul McMullen fired wide of the goal and any Rovers attacks were blocked by Cammy Kerr and Charlie Adam.
Dundee took the lead half way through the half, a delightful 40 yard pass from Adam found Jordan McGhee in the box to place a precise volley across Jamie MacDonald and into the net. It was a superb goal from the dark blues.
Dundee got lucky when Rovers scored just before half-time and it was ruled out for off side, it should have been a goal.
Second half and Dundee doubled their lead when again Charlie Adam played a superb ball to the on running Jordan McGhee who finished well.
Dundee were in total control and they were able to make changes to the team, and it paid off Adam found Max Anderson wide and he played in Osman Sow who scored the third goal to seal a vital first leg win.
Dundee now play Rovers again at Dens on Saturday, I'm sure they will prepare right and treat the game in the right manner.
