Shellharbour host Lake Illawarra for a spot in the South Coast cricket one-day final, with Oak Flats and Albion Park the other co-leaders heading into this afternoon's final limited overs round.
With four clubs level on points, countback may determine the one-day finalists, with Oak Flats and the Lakers heading into the final round in the top two positions.
Shellharbour and the Lakers clash at Tom Willoughby Oval with the winner straight into the final, while Oak Flats, with a superior run differential over Albion Park, can guarantee themselves a place in the February 3 final with a home win over last-placed Kiama.
Albion Park are fourth on countback heading into the final round and must beat The Rail at Croome Cricket Oval and hope Kiama upset Oak Flats to force their way into the final.
Given there's no semi-finals in the limited overs competition and four clubs equal on points with four wins from six matches, the competition is destined for an exciting final round.
Albion Park are coming off three straight wins to end 2012, including a thrilling victory over Oak Flats.
After finishing down the bottom of the competition last season, the Park and Shellharbour have been the big improvers in the first half of this season.
Reigning two-day champions Warilla are third last in the standings.
Warilla finished 2012 with a victory over the Lakers and are playing away to Gerringong/Jamberoo today.
One-day ladder: Oak Flats 60, Lake Illawarra 60, Shellharbour 60, Albion Park 60, Gerringong/Jamberoo 48, The Rail 36, Warilla 36, Kiama 24.
