South Star, who are also listed to participate in next week's start of the first annual Red Stripe Twenty20 championship, would join Broughton of Westmoreland should they record a victory as the only teams to reach successive finals of the event, which is now in its third season.
South Star will also have the chance to be the first team to make a successful defence of the crown. The match is set to start at 2 p.m.
opening encounter
Meanwhile, in the opening encounter of the venue's double-header, first timers St Elizabeth's Junction and St Catherine's De la Vega City will go head-to-head for the other final spot.
In the first semi-final which gets under way at 10 a.m., Junction of St Elizabeth square off with St Catherine champions De la Vega City.
Should Junction win, they would be the second team from the parish to reach the final behind inaugural champions, Lititz/Comma Pen, in 2006.
The competition attracted teams from approximately 550 communities in Jamaica. In the preliminaries, 32 teams were registered per parish and knockout rallies were used to identify the top 16 teams for the parish level.
At the parish phase, teams were drawn in four groups per parish, using a league format lasting three weeks. From there, the top-two teams from each group will advance to the Super Eight knockout in each parish.
national level
Sixteen teams - 15 parish winners (Portmore is treated as a parish) plus the best runners-up - then moved on to the national level where league and knockout formats were used to decide the national champions.
The winners of the competition will take home $500,000, runners-up $300,000 and the third-place finishers, $150,000.
