Chris Buckley belted a brilliant century for Ex Servos but Warilla's Kookas had the last laugh in the third round of South Coast cricket on the weekend.

Buckley blazed a run-a-ball 115 with 14 fours and a couple of sixes at the home side amassed 220 at Hayden Drexel Oval.

He shared a 41-run opening stand with Matthew Higham (16) and 46 for the fourth wicket with Kuldeep Singh Rana (14) but wickets kept falling at regular intervals.

At 7-146, he was at risk of running out of partners but Matthew Spinks (24) hung around as they advanced the total to 200 before they both fell in quick succession.

Veteran all-rounder Craig Bramble took 4-34 and also added 74 with the bat as the visitors reeled in the target with six wickets and as many overs to spare.

Opening partner Ethan Maker (33) and Michael Perry (40) were also in the runs for the Kookas.

Bay and Basin Dolphins were skittled for just 60 by Lake Illawarra at Sanctuary Point Oval with Jake O'Connell (3-17), Ryan Smith (3-23) and Jaycob Constantinou (2-2) the destroyers.

Lake lost five wickets in overhauling the target inside 11 overs with opener Jackson Ingram (34) the only batter to make a double-figure contribution.

At Scout Willoughby Oval, Oak Flats posted 8-229 thanks to half-centuries from captain Jack Bennett (50) and opener Kip Penfold (56) but Shellharbour got home in the 45th over.

Oran Pattison top-scored with 95 while Zaied Bin Khalid led the way with the ball for the Rats with 3-31.

North Nowra Cambewarra scored a convincing win over Kiama with Hugh Gillen (55) and Justin Weller (68) powering them to 247 at Bernie Regan Sports Ground.

The Cavaliers slumped to 3-57 and apart from opener Adam Ison's 70 and Nathan Barr's 40, no batter got going and they fell well short on 176.

In the other game, Bomaderry thumped Albion Park, who were bowled out for 178 despite 66 from captain Keegan Campion at the top of the order.

The Tigers bit back with a 103-run opening stand between captain Kealen Blattner (66) and Rhys Burinaga (71 not out) and reached the target with more than 20 overs and six wickets up their sleeve.

Lake Illawarra and Shellharbour are the only unbeaten teams after three rounds with the Rats, Park and Ex Servos still searching for their first victory.
