Bonnyrigg Rose kept a third consecutive clean sheet following 1-0 and 3 -0 wins over Newtongrange and Penicuik.
These were powerful wins by Robbie Horn’s men as they continue the defence of their 2015-16 Super League title.
In inflicting Broughty’s first defeat of the season, Rose hit their 10th goal from four league games ahead of last night’s (Wednesday) rearranged match against Camelon.
Bonnyrigg were 4-0 ahead with three-quarters of the match played but missed later chances to add more.
It did take the Rose some 31 minutes to open the scoring during a strong and determined overall display, when a Lewis Turner corner was headed home by Kieran McGachie.
It was the only goal of that first half, but with only seven minutes played in the second half, the home side doubled their advantage when a right-wing cross to the far post found Dean Hoskins whose fine volley hitting the Broughty net.
On the hour, it was 3-0 as the visiting Trialist goalkeeper made something of a hash of trying to save a Donaldson header ten yards out and it landed in the Athletic net.
Strong Rose play and good football ensured the Rose victory, and they made it 4-0 in 66 minutes with Ruaridh Donaldson the provider for Fraser McLaren, whose header nestled in the Broughty net as the home fans celebrated.
There was news of comebacks by injured Ewan Moyes and Wayne McIntosh who hoped to feature in the visit to Camelon.
But there were more injuries suffered as Rose finished with 10 men. Alex King, who came on for Lewis Turner (back injury), in the 50th minute was himself injured and taken off for treatment.
