The accurate kicking of halfback Nicho Hynes, on a surface with plenty of standing water, was key to Cronulla building pressure on the scoreboard against a Bulldogs side who were reduced to a two-man bench midway through the second half.
The match swung on a potential 12-point turnaround just after the hour mark, with the Dogs denied a try to rookie Kurtis Morrin after the NRL Bunker found a Sharks player was held back in the lead-up, before Nikora scored three minutes later.
