ARRYN Siposs approached last Monday's clash with Carlton as he would any other game day, even though he was about to live out the dream of thousands of boys around Australia.

After an impressive string of games with VFL club Sandringham, Siposs was set to make his AFL debut with St Kilda, the club he had passionately followed all his life.

As with most surreal encounters, Siposs said his concept of time was completely haywire.

"On the Monday it took forever because you're waiting just to get to the ground to get ready to go," Siposs told saints.com.au.

"Once you're at the ground it goes pretty quick from there. You do all your normal stuff to prepare for a game and things like that.

"It felt like the quickest game of my life to be honest. It was a great experience and I'm looking forward to many more to come."

The stats sheet might not indicate much of an output from the 18-year-old. He had just four touches but handled himself with poise in one of the most intense encounters of the season.

And he had a significant hand in St Kilda's last quarter revival.

Siposs took a mark 60m out from goal with his side nine points down.

Rather than panic or freeze as might be expected from a teenager in his first game, he quickly launched a long bomb from the centre square that sailed through to reduce Carlton's lead to just three points.

"I turned around and I saw the goal square free, I just thought I've pretty much got to get it in there. If I put it in there I had to see what happens and it got just over the line with a bit of help from Milney (Stephen Milne)," he said.

"I thought I'd just go for it. I think it was better that I didn't have much time to think about it rather than going back and saying 'Gee, what am I doing?'"

Siposs is a product of Beaconsfield Football Club in southeast Melbourne, the same club that produced former Blue and Lion Brendan Fevola, Richmond captain Chris Newman and ex-Saint Austinn Jones, who is now the club's senior coach.

While Siposs never played senior football for Beaconsfield he left an impression on the club, booting 99 goals in the under 16s in 2009.

It was a performance that did not go unnoticed by the Saints, who have long-term plans for Siposs as a key forward.

He says he is going out of his way to learn from the best.

"Nick Riewoldt's the guy I look up to, being the same position as him in the forward line," he said.

"I look around and see what he does during a day and the way he goes about it is so professional. It's good being in the same environment as him."
