Lake Illawarra fast bowler Jake O’Connell ripped through Oak Flats with a hat-trick on Saturday as the premiers romped to a seven-wicket win.

O’Connell dismissed opener Kody Lawler for 10, trapped Sam McLennan first ball and then bowled Adrian Bartlett from the next delivery to complete the rare feat.

He ended up with 6-30 from 9.2 overs as the Rats were bowled out for 136 despite a fighting 37 from captain Jack Bennett at Howard Fowles Oval.

Lake surged to their modest target inside 15 overs with opener Max Henderson belting an unbeaten 74 from just 47 deliveries with 15 boundaries and a six.

They have leapt into top spot after Shellharbour suffered their first loss of the season, going down to Kiama.

Opener Adam Ison (45), Nathan Barr (51) and Brad Ison (48 not out) wielded the willow with gusto as the Cavaliers racked up 7-209.

Harbour skipper Daniel Smith (49) and opener Jacob Coleman (38) provided early resistance but they went from 1-84 to all out for 143 with Brad Ison, Glenn Cleary and David Coleman snaring two wickets apiece.

Bomaderry registered a 91-run win over the Kookas at Oakleigh Park after six batters made 20 or more.

Tailenders Peter King (40) and Lachlan Duggan (27 not out) put on 44 for the last wicket as the Tigers posted 254 despite fine efforts from Kookas duo Gerard Healey (4-26) and Troy Tungai (3-60).

The home side slumped to 3-31 and never threatened the total with Rhys Burinaga picking up superb figures of 7-48.

At Sanctuary Point Oval, Bay and Basin edged out North Nowra Cambewarra in a tense clash.

Jonathan McLennan top-scored with 38 as the Dolphins amassed 177 with Hyeon Parsons the pick of the visiting bowlers.

North Nowra lost two early wickets and Elijah Guyatt (42) and Justin Weller (27) got them within striking distance but after a late collapse, they finished 35 runs short of victory.

Albion Park left Ex Servos on the bottom of the ladder after a low-scoring clash at Keith Grey Oval.

Joshua Peters came to the rescue with 37 as the Eagles posted 152 with Kuldeep Singh rana (4-21) starring with the ball for the Shoalhaven side.

He backed up with 55 in the run-chase but had few allies as Ex Servos were rolled for 125 with Peters (3-26) and Matthew Burns (3-28) doing the main damage.

This Saturday’s round features North Nowra at home to Lake Illawarra, Albion Park away to Shellharbour, Ex Servos hosting Bay and Basin, Bomaderry heading to Kiama and the Kookas clashing with Oak Flats at Oakleigh Park.

Ladder: Lake 41, Shellharbour 37, Kiama 34, Bay and Basin 33, North Nowra 28, Bomaderry 24, Albion Park 16, Oak Flats 14, Kookas 12, Ex Servos 6.
