Delisted St. Kilda ruckman Jason Holmes is hoping for a second chance at AFL level.

Holmes, 27, spent 4 years at the Saints after coming across from the United States.

The American played 5 senior games across his St. Kilda career, failing to register an appearance in 2017.

Holmes aspires to continue his AFL career however, potentially adding depth in the ruck department with another club.

"I would love nothing more than to have another opportunity to try to compete at the highest level," Holmes told the AFL.com.au.

"I can offer any team just that security that if I am picked, or a ruck goes down and you need someone to come in and still battle with the big boys at the AFL level, that I'll be in there providing the ball to the midfielders and forwards and whoever else needs it.

"I take a lot of pride in knowing my teammates appreciate my service and I get them the ball where they want it, when they want it, because when they call for it, I know that they're trusting me to get it there for them."

Holmes was grateful for the opportunity he received at St. Kilda after learning his fate via an Alan Richardson phone call whilst back in his hometown of Chicago.

Holmes said that the Saints were "getting there" in respect to their aspirations for a second flag.

"You can tell that they're moving as one and I think that's one of the most important things that you need to win a flag," Holmes said.

The competitive big-man is confident that he can be of great value to an AFL club, noting his vast improvement over his career, as well as the improvement left in him.

"My 3km time trials and everything, I started shaving those times when I arrived and I'm fitter to the point where I'm not tired anymore. I can leg out a full quarter without getting subbed off and I think that extra tank gives me more energy to win the ruck and then go play some football, go get the footy and be aggressive," Holmes said.

"I think I have so much more to improve, I think I can be more aggressive in the air. I think that's something I'll always want to work on.

"I still think I have quite a bit to improve. I've only been playing for four years and I don't have a 10-year-old footy body yet. I still think I've got a lot to give."

Clubs that could possibly look at the 203cm ruckman for a reserve ruck role include Adelaide, GWS, Melbourne, Port Adelaide and the Western Bulldogs.

Holmes will turn 28 before the commencement of the 2018 season.
