Walker said on Tuesday he was "pretty pumped" by the new contract, which he wanted to get out of the way early in the season.

"Carlton is home to me, all parties knew that, and we were all pretty confident in getting the deal done," he said.

Walker was drafted from the Bendigo Pioneers at No.2 in the 2003 national draft.

The star from Echuca has played 165 matches for Carlton.

After playing in the forward line for much of his career, and being the club's leading goalkicker in 2011, Walker was converted into a running half-back by coach Mick Malthouse last year.

The 27-year-old was runner-up to Kade Simpson for the John Nicholls Medal, the Blues best and fairest award in 2013.

Walker led the club's kicks, handball receives and rebounds from inside 50 in 2013.

"I had one of my best seasons last year and leading into this season I'm feeling a bit fitter and a bit better.

"I think I can be a multi-position player, which is where the game is heading, because I think I'm equipped to handle that sort of role. - AAP
