WA prospect Sydney Stack is reportedly set to become a Richmond player after impressing during a two-month trial at Punt Road.

The Tigers are poised to sign Stack as a rookie under the league’s new recruitment rules which allow clubs to fill list vacancies until March 15, according to AFL Media.

While widely viewed as one of the more talented junior footballers in the country, queries over Stack’s professionalism saw him overlooked in last year’s national and rookie drafts.

But the Perth product - who has been living with Damien Hardwick since moving to Melbourne in December - responded well to feedback surrounding his fitness and held his own during Richmond’s training camp in Queensland last month.

The powerhouse club has also taken note of Stack’s game sense and ball skills; traits that earned him all-Australian selection despite managing just three games during the national carnival.

If recruited, Stack will be the second player to join Richmond during the pre-season supplemental selection period after former Gold Coast and St Kilda player Maverick Weller became a Tiger in November.

Under the new rules, clubs can sign players as rookies between December 1 and March 15 to replace retired or seriously injured players, or if they have a free spot available on their rookie list.

Eligible players must have previously nominated for the national draft or been on the list of an AFL club.
