St George Illawarra moved within one win of the NRL top eight as they maintained Cronulla's WIN Stadium hoodoo with an 18-10 win over their local rivals.
With the game completed in near darkness due to a power failure just before kick-off, the Dragons held on for just the second win from their past five games, Trent Merrin sealing victory with a try 13 minutes from time which appeared to feature a Matt Cooper knock-on in the lead-up.
Stand-in skipper Wade Graham scored a double for the Sharks, who could drop out of the top four if South Sydney win on Monday night, but Cronulla remain without a win in Wollongong since 1989.
The Dragons made a horrendous start when Jason Nightingale misjudged the kick-off and could only watch as it bounced over the dead ball line.
The ensuing drop out was only marginally better, things going from bad to worse when Kyle Stanley - a late call-up for Jamie Soward (back spasms) - was stretchered from the field with a suspected torn ACL after just six minutes.
