The young Tricolours were behind 24-0 after just eighteen minutes and despite dominating for the remainder of the match couldn't quite make up the deficit in time.
Missing influential five-eighth Samisoni Langi, who made his NRL debut, the red, white and blues weren't as ruthless on the opposition line.
There were some promising signs on display in the final sixty minutes, including prop Braeden Uele who had a big game for the visitors
In the end it wasn't enough as the home side held on for a well earned win.
It was all the Tigers in the opening twenty metres as the home side forwards rolled through the Tricolours early on.
The young Tigers halves were having a field day on the back of the momentum and picked up a try each to add to four pointers by Brown and Rudolph to seemingly end the game before it even begun.
Showing the steely determination that has seen the young Tricolours rise to second on the competition ladder, the Roosters then hit back with two quick tries to add life to the contest.
A touch of luck saw Mitch Mamary pounce on a stray ball to register the visitors first before Cornish went on a jinxing run, beating three defenders to further reduce the deficit.
When Braeden Uele stormed over just before the break the Tricolours were within ten and full of confidence heading in to the second stanza.
After a tough opening, the Tricolours finally crashed over for the first try of the second half, captain Rhyse Martin powering through the line to put the visitors within a converted try.
Despite being presented with a number of chances and dominating play for the remainder of the match the young Roosters couldn't find a way over the line.
A run away try against the run of play to Kurtis Rowe for the Tigers then sealed the result for the home side.
