Sydney's Isaac Heeney has extended his lead in the AFLCA Champion Player of the Year Award standings, while eight of the nine games from Round 17 saw a player poll a perfect 10 votes.

Heeney amassed three votes from his side's loss to St Kilda to move eight clear of Collingwood's Nick Daicos, who is now 11 votes ahead of the third-placed Marcus Bontempelli.

Essendon's Zach Merrett polled a perfect 10 to move within four votes of the top five as both Bontempelli and Caleb Serong went without votes while Carlton's Patrick Cripps managed four votes for his efforts over the weekend.

North Melbourne's Harry Sheezel, Port Addelaide's Connor Rozee, Geelong's Jeremy Cameron, Giant Jesse Hogan, Demon Trent Rovers, Saint Mattaes Phillipou and Lion Lachie Neale all joined Merrett in adding 10 votes to their respective season tallies.

The game between Fremantle and Richmond was shared evenly as Docker Andrew Brayshaw and Richmond captain Toby Nankervis led the way with nine votes each.
