A field goal in the third minute of golden point by Valentine Holmes has seen Cronulla snatch a 23-22 win over Gold Coast.
The Sharks, who had trailed for most of the match, came home strongly against a Titans team down to just one fit player on the bench with David Mead, Nate Myles and Will Zillman all unable to finish the game.
Holmes, who scored a double either side of halftime to spark the Sharks' comeback, slotted the match-winner from 30m out.
It was a bitter blow for the Titans, who had looked beaten when young gun Jack Bird put the Sharks ahead for the first time in the match with just eight minutes to play.
But Anthony Don's leveller four minutes later after a great cutout pass by rookie halfback Kane Elgey gave the home team hope.
