The Jersey Flegg Sharks were made to work for it, but they eventually emerged 18-10 winners over the Wests Tigers to remain undefeated through 12 rounds of the 2018 competition.
Despite their contrasting positions on the competition ladder, the Sharks sitting in second and the Tigers at the bottom of the ladder, they only sealed the deal late, with the win moving them onto 18 points, and into a share of the Jersey Flegg lead.
The Sharks conceded the first try in just the sixth minute of the match before half back Braydon Trindall replied and after converting his own try the scores were level at 6-points apiece.
Jackson Ferris, who has made a habit of scoring tries of late, put the Sharks on top in the 28th minute and when Trindall was again on target it was 12-6 to the young Cronulla side with half time approaching.
The Tigers however would pull closer with a four-pointer and the teams would go to the break with the Sharks leading 12-10.
The second-40 turned into a defensive struggle, neither side able to assert any real dominance and it took until the 68th minute of the match before the Sharks were able to add to their score, centre Bronson Xerri crossing to give his team some breathing space and ultimately another valuable win.
It was another strong defensive effort from the Sharks, who have conceded the least number of points so far in the Jersey Flegg competition in 2018.
