Jerviston got their hands on the LFDA Cup after a battling encounter against a resilient Larkhall side.
A late Kian Marshall tap-in was enough to separate the sides and take the cup home to Motherwell.
Jerviston had recorded 26 goals in the previous four rounds and their attacking prowess was evident right from the beginning. Ryan Mimnaugh came close before Mitchell Clark's dipping 25-yard effort went inches over the bar.
Mid-way though the half, Marshall found himself in plenty of space before unleashing a wicked shot from outside the box stinging the palms of Samuel Danks for the first time.
Larkhall captain Lewis Paterson was fast becoming an important figure in the match, making vital interventions to deny a dangerous Jerviston side more goalscoring opportunities.
The team in orange had their first shot on target on the half-hour mark. Derrin Cross' tame shot lacking the power needed to trouble Ben McDougal.
Samuel Danks was called into action again seconds before half-time, Mimnaugh played in Nathan McConnell whose curling effort was turned past the post by Danks.
Chances were few and far between in this tightly contested affair at K-park, only three shots on target were recorded as referee March Lester blew his whistle for half time.
