A dead rubber before the game lived up to its pre-match billing - Mullinahone had already won the group and Boherlahan were fighting relegation and the action at New Inn on Saturday evening followed that script.
An under-strength Mullinahone did no more than they had to - their greatest worry will be a straight red card for Keith Mullally late in the game for a pull across a Boherlahan player.
Boherlahan, playing with the backing of a strong breeze, led at the break 1-7 to 0-8, thanks to an injury time goal from their outstanding player on the night, Darragh Hickey.
But they didn’t do well against the elements and five points without reply for Mullinahone in the third quarter turned a two point deficit into a three point lead, 0-13 to 1-7.
It was Hickey who had Boherlahah’s first point of the second half in the 15th minute and they only managed two more, both from Hickey, from there to the end.
With points from Michael Dunne, Cathal Horan, Graham Horan and Niall O’Brien to a Boherlahan reply from Paul Ryan, the South side raced into a 0-4 to 0-1 lead in the first quarter. Five unanswered scores from the Mid men from Laurence Hickey, Darragh Hickey (2), Seamus Leahy and Kieran O’Sullivan made it 0-6 to 0-4 and turned the tide and they should have been farther ahead but for some dreadful shooting.
Mullinahone had regained the lead approaching half time, 0-8 to 0-7, with two super scores from Paul Kelly and one each from Dunne and Shelly to a Boherlahah reply from Aidan Maher.
But Darragh Hickey completed the first half scoring with a brilliant piece of individual play to win possession, break clear of the cover and give Alan Walsh no chance in goal.
But that was as good as it got for Boherlahan/Dualla who will have to up their game if they are to avoid the dreaded drop to intermediate grade.
Three points in the second half from one player was a poor return as Mullinahone used the breeze to their advantage to pick off scores at will.
The continued absence of Eoin Kelly through injury robs Mullinahone of much punch in attack and they were also short Sean Curran and Donal Cody on Saturday but Jack Shelly, Michael Dunne, Graham Horan, Paul Kelly and Cathal Horan stepped into the breach to keep the scores coming.
