Lake Illawarra have clinched the minor premiership but the other three spots in the South Coast cricket semi-finals will be decided in this Saturday’s final round.

Rain caused havoc with the penultimate round on the weekend with three of the five matches abandoned without a ball being bowled - Kookas vs Kiama at Oakleigh Park, Bay and Basin vs Bomaderry at Sanctuary Point, Oak Flats vs Ex Servos at Geoff Shaw Oval.

Lake thumped Shellharbour to lock up first spot while North Nowra Cambewarra beat last-placed Albion Park at Bernie Regan Sportsground to move to just one point behind Kiama, who are clinging to fourth.

North Nowra need to upset the Lakers this Saturday at Howard Fowles Oval in their bid to steal fourth spot from the Cavaliers.

Kiama are away to Bomaderry, who could leap into the playoff equation from sixth if they win and North Nowra go down.

Third-placed Bay and Basin have technically not yet qualified but should be able to account for Ex Servos to ensure at least one Shoalhaven side figures in the semis.

Lake wrapped up top spot over second-placed Shellharbour after skipper Kerrod White’s 105 guided them to 235.

Veteran batter Brendan White provided strong support with 48 as Alex Brown (3-39) and Noah Wraight (3-27) led the way for the Harbour attack.

In reply they lost two early wickets and despite 53 from opener Jacob Coleman, they fell well short of their target, all out for 164 thanks to Jaycob Constantinou’s 3-14 and Ryan Smith chipping in with 3-17.

North Nowra were in early trouble at 3-39 against Albion Park but Nathan Thomas carved out a fine captain’s knock of 77 to propel them to 163.

Kynan Barton (3-54) was the pick of the Eagles bowlers but their top order crumbled to be 4-15 and they only managed 82 to remain in wooden spoon territory heading into the final round.

Cooper Bramley, Jason Moschioni and Matthew Hickmott struck three times each for the hosts.

Park need an upset on home turf against Shellharbour this Saturday to avoid finishing last while the Kookas are away to the Rats in the other fixture.

Ladder: Lake 104, Harbour 87, Bay and Basin 83, Kiama 79, North Nowra 78, Bomaderry 71, Rats 45, Ex Servos 40, Kookas 39, Park 35.

In the women’s competition, Lake Illawarra clinched the final playoff spot ahead of Kiama after rain washed away the final round.

The Lakers will face Kookas in one semi with the two Oak Flats teams - the Ratettes and Ratatouilles facing off in the other sudden-death clash.

Ladder: Kookas 48, Ratettes, Ratatouilles 32, Lake 30, Kiama 24, Ex Servos 22, Park 20, Harbour 8.
