With both schools having beaten Coláiste Iosaef of Kilmallock, progression to the last 16 was assured but this game was to determine the pairings in the knockout stages.
Doon started well, with William Barry their main scorer as they built a 0-8 to 0-3 half-time lead, with Jack Ryan and goalkeeper Ryan Heneghan also impressing.
However, six consecutive points from Christians, with Eoin McCarthy, Mark Walsh and Tommy O’Connell all scoring, put them in front in the final quarter. Doon didn’t panic though, Barry scoring twice, and while Christians pulled a point back, Barry’s 65 clinched victory.
At Goatenbridge, Lismore’s Blackwater CS beat CBS HS Clonmel by 5-10 to 0-11. Gavin Dalton scored three goals for Blackwater while Tom Barron got 1-8, Darragh Buckley 1-1 and Ben O’Brien a point.
Meanwhile in the Corn Uí Mhuirí (U18½AFC), Pobalscoil Sliabh Luachra were 3-11 to 1-14 winners against St Flannan’s College in Mick Neville Park in Rathkeale, coming from four points down at half-time.
Flannan’s were 0-11 to 1-4 in front at the break, Michael Mahoney with the goal for the Rathmore school, but further goals by Ian Roche and Brian Friel helped to turn the game their way in the second half. Friel was heavily among the points while Jack Cremin excelled in defence, and a win against Skibbereen CS will secure a quarter-final place.
