In the first ten minutes they could have scored four times but somehow missed the target when in great positions. They hit the bar as well in these attacks.
The first goal came two minutes later when Luke McCowan combined in a fast attack with Tiffoney before passing across goal for Curtis Main to knock home from close in.
Three minutes later Robertson sent a free kick from the left, just outside the penalty area, and Antonio Portales flicked in the second goal. Dundee got their third goal all in five minutes when Tiffoney raced wide and his ball in was knock home by Lyall Cameron.
Dundee kept going and Tiffoney was unlucky when his effort was cleared off the line, Dundee got their fourth goal after 31 minutes when Cameron ran through the middle, took a neat backheel from McCowan and set up Curtis Main to smash in his second of the afternoon. A very well worked goal which must have left Bonnyrigg stunned.
At half time Josh Mulligan came on for Ethan Ingram and his pace, strength and skill gave the beleaguered Bonnyrigg defence yet more problems to cope with.
After 52 minutes a Dee corner on the right was cleared to the left. Tiffoney crossed and Main headed on for Ryan Astley to score from a few yards out.
Half through the second half and Dundee scored a great goal wonderful passing involving McCowan and Cameron, and Lyall Cameron ran on to score the sixth goal.
Dundee kept at it and Main just missed the target and McCowan hit the post. But against the run of play Bonnyrigg scored a goal. It was a bit sloopy one for Dundee to lose.
However they picked it up again and scored number seven when a corner was not cleared and Cameron chipped the ball in for Curtis Main to get his hat-trick.
Dundee kept at it but failed to get goal no 8. It was a wonderful performance and least thy have a goal differnce in the group.
Only down side was the injury to Charlie Reilly who had to go off .
