The Sharks have enjoyed a record-breaking night at Southern Cross Group Stadium with their Holden Cup side putting on a clinic in an 84-6 win over the Wests Tigers on Saturday.

Cronulla became the first team to reach 80 points in competition history while they equalled the biggest margin in an NYC game set by the Panthers in 2012 (78-0 over Gold Coast).

It looked like the table-toppers would fall short of the record but two tries in the final three minutes - including one to Tony Matautia just before the full-time siren - saw them enter the annals of history.

It was the second time the Sharks had scored 70 or more points this season and bettered their haul of 78 against the Sea Eagles in 2012.

Halfback Kyle Flanagan scored a double and kicked 12 goals to go past 200 points for the season while back-rower Briton Nikora wreaked havoc with a first-half hat-trick.

The Sharks started the round level on points with the Panthers and must now be the overwhelming favourites for their maiden NYC title.
