St George Illawarra shocked Melbourne 26-18 on Friday night, with winger Brett Morris maintaining his incredible record at WIN Stadium with a hattrick.
The win moves the Dragons into equal eighth spot on the NRL ladder, keeping their finals destiny well and truly in their own hands in front of an impressed crowd of 11,477.
But alarm bells will certainly be ringing at the Storm, who have suffered their first five-game losing streak since 2002 - the year before Craig Bellamy took control at the club.
The Storm welcomed back fullback Billy Slater from a knee injury but even that wasn't enough to stop their slide from premiership favouritism.
Less than a week after getting knocked senseless in the brutal shoulder charge that earned South Sydney's Greg Inglis a three-match suspension, Dean Young was fantastic for the home side, while Nathan Fien was tremendous filling in for the injured five-eighth Jamie Soward (back spasms).
