Sandilands polled 20 votes to take out the award from teammate Michael Barlow and West Coast’s Matt Priddis, who were tied for second.
Fremantle coach Mark Harvey was on hand at the Bill Walker Room at Subiaco Oval on Wednesday morning to accept the award on Sandilands’ behalf.
He said the ruckman has had a fantastic year and deserved the award.
“It’s one thing to get to a level as an AFL player,” Harvey said. “The next level is to go beyond that and become a great player and Aaron’s managed to do that.”
Sandilands won the 2009 Doig Medal as Freo’s best and fairest player and was also selected in last year’s All-Australian team.
