CALLUM Ah Chee has kicked two last-quarter goals to help Western Australia to an 18-point win over Vic Metro on Friday.

Ah Chee, who is seen as the leading NAB AFL Draft prospect from WA this year, added important class in the forward line in his state's 11.6 (72) to 7.12 (54) win.

The 17-year-old, whose older brother Brendon made his debut for Port Adelaide this year, has had indifferent form during the NAB AFL Under-18 Championships but enjoyed his best game of the carnival at Simonds Stadium.

He gathered 13 disposals, showed his smarts overhead with six marks and sent the ball inside 50 four times to go with his two goals, which were among five WA slotted in an impressive final term.

It was their first win since a one-point victory in round one, having lost their past three games by an average of 84 points. The loss leaves Metro at the bottom of the division one table, having only recorded one win (over Western Australia in round four).

Brayden Hackett added some drive through the midfield with 19 disposals for WA, and Clint Hinchliffe had another solid game with 18 disposals and six clearances.

Bottom-aged pair Sam Petrevski-Seton and Sam Powell-Pepper showed glimpses of why they are rated highly for next year's draft with 14 disposals each, while Kade Stewart collected 13 disposals and kicked a goal after the siren to cap the win.

Vic Metro's best player was small midfielder Jade Gresham, who worked tirelessly to find 20 disposals.

The 177cm Northern Knights captain belies his size to influence games in a number of ways, and he finished with five tackles, six clearances, six inside 50s and two goals.

Nick O'Kearney was prolific again with 28 disposals, and fellow Calder Cannons prospect Callum Moore was strong in the air in attack for Metro, taking seven marks and kicking 1.3. 

The 193cm forward was overlooked at the 2014 draft but has overcome injury earlier this season to put himself in the frame for this year's intake with some eye-catching moments.

Metro will face South Australia next Wednesday at Etihad Stadium, before WA takes on title-winners Vic Country on Thursday at Simonds Stadium to close the 2015 under-18 championships.
