CARLTON father-son prospect Jack Silvagni kicked six goals to help Vic Metro to its first victory of the NAB AFL Under-18 Championships, beating Western Australia by 74 points. 

With his father – Blues list manager and former great Stephen Silvagni – in the Domain Stadium stands, the 17-year-old showed his class and composure near goal with a strong display in Metro's 19.7 (121) to 7.5 (47) win.

His goals came from a range of spots inside 50, but the Oakleigh Chargers forward converted his shots well and also pushed a little further up the ground to gather 18 disposals and seven marks.

Silvagni, who doesn't turn 18 until December, returned to Metro's team after being rested last week and put together his most dominant game at under-18 level. 

He is one of several father-son prospects available to the Blues this year, alongside Bailey Rice (the son of Dean) and Jake Bradley (son of Craig). Rice is also eligible to join St Kilda under the rule. 

Stephen, who started his role at the Blues after being list manager at Greater Western Sydney during the club's inception, has already said he will play no part in the Blues' decision whether they nominate Jack as a father-son player at the end of the year.

Despite heading into the clash winless after three rounds, Metro proved too powerful for WA. Midfield pair Ryan Clarke (27 disposals and three goals) and Jade Gresham (26 disposals and a goal) were excellent, while Harley Balic continued his very good carnival with 20 disposals and nine marks. 

Crafty small forward Hisham Kerbatieh kicked three goals, and Blake Hardwick and Callum Moore chipped in with two apiece for Metro. 

Since winning its first game of the championships by a point, WA has been beaten by an average of 84 points the past three games.

Clint Hinchcliffe tried hard for his state, gathering 24 disposals and sending the ball inside-50 on six occasions, and Kade Stewart had 15 touches in his first game of the championships after recovering from a long-term leg injury.

Jordan Snadden also had 15 disposals through half-back and the midfield, while Greg Clark's athleticism took the eye at stages as he found 14 disposals and kicked a goal.

The division one title could be all but decided on Sunday when Vic Country plays South Australia at AAMI Stadium. If Vic Country wins, it will be almost unassailable in claiming this year's championship victory.
