CBC Monkstown and Wesley College will meet in the Leinster Schools Vinnie Murray Senior Cup final at Donnybrook next week after both secured facile victories yesterday.
Gormanston began brightly against Wesley with Tom Downs crossing, but their lead was short-lived as Gary Howe scored the first of the Dublin school's 10 tries in a 67-14 rout.
Back-row David Moran and centre Adam Culbert each bagged a brace for Wesley, who progressed to the final in some style.
Monkstown were equally impressive in booking their place in the final as they raced into 21-0 lead over Tullow Community School inside the opening 10 minutes.
James Reynolds converted eight of Monkstown's nine tries as part of a 21-point personal haul in a 61-7 success, while centre Darragh Forster, wing Conor Newman and prop Max Read all registered tries for the victors.
Tullow remained dogged and scrum-half Dave Tobin scored a hard-earned try, which Padraig Roche converted.
Meanwhile, Bandon Grammar School produced an amazing comeback to beat visitors Castletroy College 24-17 in the opening round of the Clayton Hotel Munster Schools Senior Cup.
The Limerick school moved into a 17-7 lead in the second half, but they wouldn't score again while Bandon ran in three tries to snatch victory.
