Jaidyn Stephenson has finished his under-18 season in brilliant fashion by having a best-afield performance in the NAB AFL All Stars clash at the MCG on Saturday.

In the curtain-raiser to the Richmond and Adelaide premiership decider, Stephenson kicked three goals from 22 disposals to lead Team Harvey to a 55-point win over Team Enright.

The teams in the exhibition game were named after North Melbourne champion Brent Harvey and Geelong great Corey Enright.

It was Stephenson's day, though, with the Eastern Ranges product producing a scintillating display through the midfield and in attack in the 17.8 (110) to 8.7 (55) victory.

He shapes as a likely top-10 pick at November's draft having transitioned into the midfield this year. He wasn't a lone hand for his side, which was coached by Western Australia's under-18 coach Peter Sumich.

Lochie O'Brien had one of his best games of the year with 24 disposals and a goal after spending more time in attack in the second half, while possible No.1 pick Luke Davies-Uniacke gathered 23 disposals, six marks and also booted a goal in a commanding midfield effort.

Livewire Brent Daniels (23 disposals, one goal) was good in the midfield while Aiden Bonar impressed with a goal from 20 disposals in arguably his best game of the year having returned from back-to-back knee reconstructions.

Hayden McLean also booted three last-quarter goals to finish with four majors, and Northern Territory prospect zipped around with 18 touches.

James Worpel was the best player for Team Enright, gathering 21 disposals and seven clearances in a typically hard-working effort, while Richmond's father-son prospect Patrick Naish had 21 disposals.

WA pair Brayden Ainsworth (20 touches) and key forward Oscar Allen were also very good for the losing side, with Allen kicking 2.3 from 18 disposals and seven marks.

Jack Petruccelle showed good pace and kicked a goal, while possible Greater Western Sydney academy pick-up Nick Shipley found 19 disposals.

The clash followed Friday's under-17s All Stars game at Simonds Stadium, which featured prospects for next year's draft.
