Four rapid-fire tries in the second half have helped Cronulla burst St George Illawarra's bubble with an important 34-12 win in their NRL clash in Sydney.
The Dragons were trying to keep the magic alive for a second week running after toppling reigning premiers Brisbane last weekend.
But the Sharks unleashed a 15-minute scoring spree at Ocean Protect Stadium on Sunday, starting with a Briton Nikora angled run, followed by a William Kennedy swan-dive under the posts, then sideline speed from wingers Sam Stonestreet and Ronaldo Mulitalo.
It turned a 12-6 halftime deficit for the Sharks into a 16-point lead - and the Sharks weren't finished.
Another converted try in the final 10 minutes meant 28 unanswered points in the second half would ensure Cronulla remain in the top eight, rising from eighth to sixth.
