Despite taking an early lead, the Killoe side found themselves trailing to O’Mahony’s by two points at the break.
Ruairi Ó Coileain’s goal in the first half had given his side the lead in the 20th minute. They led by two at the break.
O’Mahony’s put three between them at the start of the second half but then Killoe came back, with Michael Quinn kicking over a fine point in the 35th minute.
Cousins Joe and Sean McCormack (two) hit over points while midfielder Simon Kiernan kicked over two excellent points to put his side ahead by three in the 43rd. ’Mahony’s cut the gap to one in the 52nd minute with points from Shane Gillespie and Ruairi O’Coileain.
Both sides then squandered chances. In stoppage time, Mark Hughes was fouled and Sean McCormack kicked over the free.
O’Mahony’s knew they needed a goal if they were to claim a dramatic win but the Killoe defence were resolute.
O’Mahony’s misery was compounded when Ó Coileain was sent off for striking Hughes.
