Pat Allan's U19 Reserves had an 82 point victory over arch-rival St Kevins, opening with a five goal first term and finishing the game in the same fashion.
Gus Lachal kicked five and Matt Perrett three, while the Bernies had no answer to the workrate and skills of Jack Christopher.
The Rs sit just behind Old Scotch in second position. The Rs lost narrowly to those Red Men in R1, but given St Kevin's are the third-placed team, there is plenty of confidence that the Red 'n' Blacks can continue their momentum over a long run to the finals.
