Livingston returned to the form which saw them clinch the championship last week by demolishing Montrose at Links Park, consigning the Angus side to finish the season in bottom place.
Gary Bollan decided to give some of the promising youth players a run out, and remarkably only one of Livi's starting XI was over 21 years old. The game also saw three of the four Jacobs brothers take to the field together for the first time.
It was a fairly evenly matched first half until Andy Halliday slotted home a fine De Vita cross to give the visitors a narrowly deserved interval lead.
The second half however proved to be an entirely one-sided affair as Livi took complete control of the game. Raffa De Vita doubled the scoring from just inside the box before
Halliday grabbed his second with a superb strike from distance.
Gemmill managed to find the net for the home side, but his effort was disallowed for offside. This was immediately punished as Paul Watson's close range header made it four for the champions.
Livi continued to dominate, with Tosh and Sinclair running the show in midfield. And this constant pressure was rewarded when sub
Keaghan Jacobs completed the scoring by tapping home number five.
