A Scottish Cup tie of no bookings at New Dundas on Saturday saw the Rose hit Montrose Roselea for six to progress to the next round.
The final score could have been more as the Rose led comfortably 5-0 at half time.
With the visiting keeper doing his utmost to keep the score down as the Midlothian men ran riot.
Bonnyrigg outplayed their opponents in that first half netting three goals in the opening ten minutes.
Ewan Moyes started off the goal fest for the home side in just three minutes heading home to make it 1-0.
This was followed just four minutes later when Andrew Kidd’s header also found the Montrose net.
Next a goal from Wayne McIntosh following his run and shot kept the home fans in joyous mood as Bonnyrigg raced into a comfortable three goal lead.
A third headed goal, this time by Kieran McGachie in 29 minutes, raised the Bonnyrigg tally to 4-0.
Before Scott Gray netted number five on 35 minutes via a slight deflection.
In challenging weather conditions Bonnyrigg had ruled for most of the first half with the half time 5-0 scoreline reflecting that.
It was into the second half before a Stephen Greig consolation goal was netted for Montrose Roselea.
Although a mere consolation, the home side would have been disappointed given that it was the first goal Bonnyrigg’s keeper Michael Andrews had conceded since his arrival on September 5.
He did get a big hand to the ball but could not stop it reaching the net.
Motrose Roselea put on a brave face in the circumstances but overall were inferior to Bonnyrigg who just did what they had to do and in the end they could have easily scored more goals in this match.
Goal number six came from substitute Fraser McLaren on for McGachie as the Rose strolled into the third round of the Scottish Cup.
East Super League Bonnyrigg Rose simply had too much for East Premier League Montrose Roselea despite their being just one league between them.
This coming Saturday Bonnyrigg are again at home, to entertain Bo’ness United in the Super League. The BU’s were also at home last Saturday in the Scottish Cup beating Aberdeen East End by 5-0.
