Shellharbour will look to close in on outright victory next week after dominating day one of their clash with Albion Park on Saturday.
The hosts showed little signs of rust at Tom Willoughby Oval as the South Coast Cricket two-day competition resumed after the Christmas break. Captain Ned Taylor won the toss and sent Albion Park into bat, a decision that was vindicated as the visitors were bundled out for 106 in the 65th over.
Alexander Brown was the pick of the attack with 4/24 off 18 overs, while Mitchell Watterson and Corey Evans took two wickets apiece.
In reply, Shellharbour were in early trouble when Watterson fell for a duck but the side recovered to finish the day at 2/71 after 24 overs.
Taylor remained 52 not out at stumps and will look to push on when play resumes next Saturday.
Elsewhere, Lake Illawarra will also push for an outright victory following a dominant opening day against Kookas.
Captain Scott Peachman won the toss and batted first, but was left to rue the decision as Kookas were bundled out for 77 in the 45th over. Kerrod White led the way with 5/13 off 16 overs for the hosts. In reply, Ryan Maguire and Brendan White remained unbeaten on 55 and 45 respectively, as the Lakers finished 3/181 at stumps.
And The Rail will look to keep building next week after a solid day with the bat against Kiama on Saturday.
Brynley Richards top-scored with 92, while Dylan Rae and Kieran Gilly both posted half centuries as the visitors compiled 4/237 from 86 overs. Thomas Norris was the pick of Kiama's attack with 2/28 off 10 overs.
