St Brendan’s had 22 points to spare over Hamilton High School in this desperately one-sided Group C fixture at Aghabullogue, with Mark Hartnett and Donnchadh O’Sullivan raising green flags for the winners.
David Shaw and Dara Moynihan were also heavily influential in front of goal in this 2-24 to 0-8 rout.
Coláíste Chríost Rí were also untroubled in maintaining their unbeaten form in Group B. The Cork City outfit overcame last year’s finalists, Clonmel High School, by 2-9 to 0-5 at Cappoquin. The Tipperary school could manage only the solitary point in the opening half, a 26th-minute Jamie Roche free.
They trailed by 0-7 to 0-1 at the break and were left chasing a lost cause when Coláíste Chríost Rí inside forwards Mark Cronin and Cillian Myers Murray both found the net in the second period.
The winning full-forward line was to have a major say, with Cronin (1-4), Murray (1-3), and Mark Brosnan (0-2) supplying their 2-9 total.
In the other Group B fixture, Mercy Mounthawk crushed Clonakilty Community College to 3-16 to 0-8 to progress to the quarter-finals.
In Group A, St Francis College, Rochestown edged out Coláiste na Sceilge by the minimum at Lewis Road. James Holland goaled early for Rochestown, but the Kerry outfit hit back with goals from Luke O’Shea and John Murphy to level matters at the break, 2-3 to 1-6.
Holland and Liam Grainger were to the fore in the second period in helping Roco across the line.
The eight quarter-finalists are Tralee CBS, St Francis College, Rochestown, Coláíste Chríost Rí, Mercy Mounthawk, St Brendan’s, Killarney, IS Killorglin, St Flannan’s and Pobalscoil Chorca Dhuibhne.
