REIGNING Geelong best and fairest Cam Guthrie has committed to a new deal that will tie him to the Cats until at least the end of 2025.

Guthrie, who turned 29 in August, will remain with the Cats until the age of 33 after the fresh four-year extension.

Also a Therabody AFL All-Australian last year, Guthrie's strong form has continued in 2021, averaging a career-high 29.1 disposals per game.

Guthrie this year qualified as an unrestricted free agent but had been holding off on signing a new deal in order to receive greater career security with a four-year contract.  

The decision follows the long-term agreements from the Cats in recent times with Patrick Dangerfield (2024) and Mitch Duncan (2024).

Guthrie joins Jeremy Cameron (2025) with the longest current contract at GMHBA Stadium.

Despite his recent personal success, Guthrie would love nothing more than to taste team glory.

"Going back to 2011 and that being Geelong's last grand final win, projecting forward from then it was always a goal of mine to get in that group and be a premiership player," Guthrie said.

"There's been opportunities over those years, but haven't quite been able to go all the way ... 2021 is another opportunity.

"We want to be here when the whips are cracking and we are again. I'm really enthusiastic about our prospects."

Guthrie's brother Zac and ruckman Rhys Stanley are also out of contract this year, but both are likely to receive extensions.

"We both love playing with each other, we both love representing Geelong," Guthrie said of his brother Zac.

"We can both hopefully do that for years to come." - With AAP
