Fast-running Demon Dean Kent has told Melbourne he wants to be traded to St Kilda.

The 24-year-old, who has been offered a three-year deal to join the Saints, told the club in his exit interview on Tuesday he wants a trade.

The fast half-forward has had a difficult past two seasons with hamstring and shoulder injuries and fluctuating form. He only played 11 games in the last two years after a career-best 20 games in 2016.

Kent had overcome hamstring problems and was back in the Demons side in the final rounds of this season before suffering a shoulder injury in a collision with Lachie Whitfield in round 23. That injury cost him a place in the side for the Demons in the finals.

His manager Ben Niall confirmed the move, saying the Saints planned to use his pace throuth the midfield.

"Dean is grateful to Melbourne for the opportunity to play AFL football and the support they have offered him. He has nothing but respect for the club but he wants more opportunity to play in the midfield and more security for his new family.

"Dean sees the Saints as a chance to play a bigger role in leadership on and off field as they rebuild the club and he is excited by the opportunity and cannot wait to get stuck into pre-season," he said.

Kent's wife gave birth early, to a baby boy on Monday night.

Kent's decision to ask for a trade to St Kilda came as Melbourne also announced they had delisted Cam Pedersen and Tom Bugg.

St Kilda want to bring in more depth, pace and run to their midfield. They will look to trade in Dan Hannebery to bring in more experience and class when he is fit, even if he does not add pace. Kent brings pace and run to a one-paced midfield and for a club lacking draft picks he can most likely be brought in for minimal trade terms.
