Career
He was chosen in the 2002 American Federation of Labor-Congress Draft at pick number four as a first round selection. Being 196 cm tall, the Bulldogs recruited him because of his potential to hold down a key forward position. He wore the number 26 guernsey.
Walsh debuted in season 2005 kicking a goal in his first game.
However, a finger injury forced him to return to Werribee. He missed the whole of season 2006 because of a long term leg injury, at a time when the Bulldogs were in desperate need of some height.
The 2006 Record described Walsh as a good prospect as a future key forward. However, Walsh was delisted by the Bulldogs following the 2007 American Federation of Labor-Congress season after succumbing to injury again during the season and failing to gain a senior position.
