They’re flying high at the apex of the NRL premiership ladder and Wests Tigers have had another win with one of their band of young stars committing his future to the club.

It’s not James Tedesco, not yet anyway, with the injured fullback still to finalise a new contract, but there is no shortage of contentment at Concord at news that Curtis Sironen has agreed to a three-year deal that will keep him at the Tigers until the end of the 2017 season.

The Tigers will announce the re-signing of the 20-year-old City Origin representative on Thursday.

The Sironen name is synonomous at the Tigers thanks to the storied career of his father, the former Balmain, NSW and Test forward Paul, and the retenion of Curtis is the latest piece in the puzzle to come together for a club which is home to some of the game’s most promising young players.

Already NRL halfback Luke Brooks and their other richly talented teenage playmaker Mitchell Moses have been signed to long-term deals, and the Sironen development leaves the Tigers now just needing to persuade Tedesco he belongs there.

Exciting winger David Nofoaluma also extended his tenure with a three-year contract only a fortnight ago.

The Tigers are investing in their wonderful crop of youngsters after the departure last year of Benji Marshall and the performances of Brooks, Tedesco and Nofoaluma in their drive to a share of the competition lead after seven rounds is giving fans a tantalising glimpse of what they may be capable of.

Sironen was a year above Brooks and Moses as a schoolboy at Holy Cross Ryde and played most of the last season in the halves for the Tigers before being having his 2014 campaign interrupted by a foot injury which continues to sideline him.

He had been tipped as a future Australian five-eighth by Bob Fulton when he made his NRL debut in 2012 but at 195cm and 104kg there are plenty suggesting his future lies in the back-row. He is not due back from injury until midway during the season and could find himself there when he re-emerges on the first-grade scene.

Sironen’s younger brother Bayley is also on the books at the Tigers and is rated highly enough to have been included in Laurie Daley’s Emerging Blues camp for players between the ages of 16 and 18 held over the summer.

The Tigers are hoping to soon wrap up the re-signing of the in-demand 21-year-old Tedesco, whose bright start to the season made him one of the hottest properties on the open market.

The finalising of the deal has been delayed by Tedesco’s manager Sam Ayoub being overseas.
