A second half Tomas Cosgrove header earned Larne a 2-1 win over Glentoran in the County Antrim final to make it four in a row in the competition.
Cian Bolger opened the scoring before half-time, while David Fisher levelled the game shortly after the break.
However, just like he did two years ago, Cosgrove headed home what turned out to be the winner as Tiernan Lynch’s men claimed the first silverware of the season.
