Midfielder Kieren Jack further validated his decision to choose AFL over his famous father's sport of rugby league by winning Sydney's best and fairest award on Friday evening.

Jack, 23, won the Bob Skilton Medal with 553 votes, just ahead of two players in their first season with the Swans.

Former Geelong ruckman Shane Mumford polled 545 votes and ex-Hawthorn midfielder Josh Kennedy 542.

Jack, the son of former Kangaroos fullback Garry Jack, didn't play Australian football until he was 12 years old.

Initially renowned as a dogged tagger, Jack developed an attacking side to his game in 2010, almost doubling his combined goal tally for the first three seasons of his career, booting 21 this year.

The 177cm midfielder recently signed a new three-year contract with the Swans.

Kennedy, who also played all 24 games this season, was named Sydney's best player in the finals.

Midfielder Dan Hannebery added Sydney's Rising Star Award to the national Rising Star Award he had already won.

In other awards, dual Brownlow Medallist Adam Goodes was named the Players' Player, former Canadian Test rugby back Mike Pyke the most improved player and utility Ted Richards the best clubman.
