The Bray train keeps on running with Marie O'Toole's team now just one game away from ultimate victory following this fantastic win at the Coláiste Eoin gym on Monday.
Bray did not have things their own way with Irish panellist Jason O'Keefe really putting it up to the seasiders in the third quarter.
But, in Andy Bartley, Bray had the man for the occasion, the Bray man putting in a series of crucial rebounds and blocks on the back court to keep out Ballingcollig's big men.
Added to that was the contribution of Lorcan Murphy who, although relatively new to the game, is proving to be one of the most lethal inside players in the country at the moment.
Murphy's athletics background has certainly proved very useful, his take-off from the floor allowing him to record numerous lay-ups during the games.
Added to that was Murphy's terrific ball-to-hand coordination, which allowed him to take a series of outlet passes throughout the game.
Murphy would finish the game on 24 points, and not far behind was Brendan O'Neill, whose terrific display against St Aidans CBS in last month's Eastern Regional league final earned him an Evening Herald Sports Star of the Week Award.
Bray (having led 14-13 at the end of the first), opened up the first big lead of the game early in the second, with a three-point play from Murphy the launchpad for a 12-0 unanswered run.
That was to leave Bray 31-20 up at the midway point, but four baskets from O'Keefe was a reminder that Ballincollig, under Irish under-18 coach, Francis O'Sullivan, were not out of the game yet.
Bray, however, answered the call, with Murphy, Bartley and O'Neill picking off late baskets to re-establish their 11-point lead at the end of the third 46-35. And although O'Keefe and Colin Murray endeavoured to keep the Cork outfit in touch, Bray's possession game allied with some terrific powerplay from Murphy ensured Bray's passage into next Monday's decider.
