South Coast cricket premiers Lake Illawarra celebrated wins in first and second grade in the T20 competition finals at Geoff Shaw Oval on Sunday.

The Lakers knocked over Oak Flats in a rain-interrupted clash in the main game after their second-graders accounted for Gerringong in the curtain-raiser.

After the Rats opted to bat, they were in strife at 4-29 after Jake O’Connell (2-25) and Jarryd White (2-32) ripped through the top order.

Shawn Condello counterattacked for the home side with 41, including six boundaries, as they scrambled to 9-107.

Off-spinner Rafiulbari Angan struck in the second ball of Lake’s run-chase but after a rain delay, captain Kerrod White’s unbeaten 45 from 41 and 25 from opener Jackson Ingram propelled them to the revised target of 81 from 13 overs for the loss of just two wickets.

The Rats were disappointed with the result but thrilled to qualify for the final in their first season back in the top grade after a two-year absence.

The Jets crumbled in reply to be 6-38 before recovering to post 100 but nowhere near their target with Aaron Henry (3-12) and Jamie Crowhurst (3-16) the destroyers.
