The 24-year-old booted six goals in the Demons' drought-breaking grand final victory over the Western Bulldogs in September.

Fritsch will extend his time at Melbourne for at least another five seasons.

"As a club we are thrilled that Bayley has committed long-term and is he is determined to help Melbourne achieve sustained success," Demons list manager Tim Lamb said.

"Bayley has developed into one of the most consistent and damaging forwards in the competition, something which was obviously reaffirmed by his impressive grand final performance.

"He has worked incredibly hard on his game since arriving at the club and is much loved and respected by his teammates and staff alike."

Since debuting in 2018, Fritsch has played 89 games for Melbourne and booted 118 goals - 59 of them coming this year.

"Pretty exciting times coming off a year where we broke a 57-year premiership drought," Fritsch said.

"We've been building a connection for a number of years now and that's only going to get stronger."

Fellow Melbourne premiership stars Christian Petracca and Clayton Oliver also signed contract extensions during the year.
