Lake Illawarra and Oak Flats meet for the second time in six days in today's South Coast final at Geoff Shaw Oval.

The Lakers booked their spot in the one-day decider with a tough win over Kookas, while Oak Flats ended the seven-round one-day season as the top side despite a final round washout against Kiama.

Lake Illawarra thrashed a depleted Oak Flats by 143 runs in a round of 16 SCG Cup clash last Sunday.

Lakers all-rounder Kerrod White smashed 104 as the home side made 8-221 then took 4-18 when the Rats were dismissed for 78.

This afternoon's clash is a rematch of last season's one-day final, won by Oak Flats, while Lakers went on to beat Oak Flats in the two-day premiership decider.

The Lakers and Oak Flats have each won two of the past four South Coast one-day titles.

Meanwhile, the other eight clubs begin their Christmas break, with the competition resuming with the first of five two-day rounds on January 11.

Oak Flats head into 2014 as premiership leaders, though just 18 points separate them from fifth-placed Albion Park.

Second-placed Shellharbour ended a three-game losing streak with last Saturday's win over The Rail. With Albion Park's match against Gerringong-Jamberoo washed out, Lakers leapfrogged Park into fourth with their win over Kookas.
