Five-try Blackrock College tore Terenure College apart this afternoon as they impressively moved to the top of the Division One table.
Team captain Shane Byrne and wingers Shane Monahan and David Rowan (3) all crossed the whitewash in a one-sided derby match at Stradbrook.
Hooker Byrne, providing the inspiration for his young team-mates, started the scoring with a pushover try.
Darragh Fitzpatrick, one of the league's form out-halves, flicked a penalty through the posts for 8-0 and 'Rock were beginning to motor.
Terenure, who were edged out 19-16 by Clontarf seven days ago, struggled to cope with the power and pace of the Blackrock backs.
Boyne product Monahan rivals Shane Horgan in physique and he once again proved a difficult man to stop today.
He charged over from just outside the visitors' 22 for a well-worked second try for the home side.
'Rock suffered a blow when they lost first choice full-back Niall Morris to an injury, but his fellow underage international David Madigan was an able replacement.
Losing flanker Jayden Hill to a yellow card did curtail Blackrock's attacks coming up to half-time.
But although David McAllister booted a penalty for 'Nure, Rowan nipped over for his first try to hand 'Rock an 18-3 half-time advantage.
Rowan put his stamp on the game in the second half as he notched another try, close to the hour mark, and got on to a long cut-out pass to complete the rout with his third try.
