Originally rookie listed with Hawthorn for the 2004 season, Rix did not play a game for the club but continued to be an important ruckman in the Victorian Football League (VFL) with the Box Hill Hawks.
This form saw him recruited as the number 49 draft pick in the 2005 AFL Draft from Coburg to the St Kilda Football Club, a side that had problems in the ruck department with usual second-stringers Cain Ackland and Jason Blake shouldering huge responsibility.
A mature age recruit at 25, Rix was drafted in a bid to improve St Kilda's ruck stocks; however, it was not until Round 11 his first season in 2006 when he made his debut against the Sydney Swans.
Rix started the 2007 season as a back-up ruckman to new recruits Matthew Clarke and Michael Gardiner.
Rix currently resides in the United States, where he spends his time writing love letters for friends, befriending local celebrities and captaining an exclusive run club, West Village Athletic.
