Young St Kilda forwards Paddy McCartin and Jack Lonie are entering the business end of their second pre-seasons and are thriving on an increased workload this summer, says Saints forward line coach Aaron Hamill.

The Saints committed to a patient approach with their No. 1 pick McCartin in his debut season, dipping his big size 14 toes in the pool without getting him wet, preferring to allow him to develop at Sandringham out of the spotlight.

McCartin played six games across 2015, demonstrating his ability to command the arc and haul in big marks under pressure against Melbourne in the second half of the season. He took nine grabs that day, including five contested to provide the Saints faithful with a glimpse into the future.

At just 19, the expectations are realistic inside Linen House Centre ahead of McCartin’s second year, but Hamill revealed the budding key forward is ticking the boxes this pre-season.

“He’s another one who’s embraced what’s thrown at him. We know he loves to compete and loves to get involved,” Hamill told saints.com.au.

“The six games we saw, I guess that Melbourne game was a little taste of hopefully what we can see with Paddy. He had five contested marks that day.

“He’s progressing nicely, doing most of training. He’s the type of bloke who just loves the game simulation, he loves to compete and get his hands dirty. Paddy’s tracking along really well.

Livewire small forward Lonie was one player who exceeded expectations in his first season, with the polished left-footer playing 16 games to establish himself as a regular member in Alan Richardson’s forward setup.

Despite an impressive start to his career, Hamill says Lonie has definitely not been resting on his laurels during the summer months, with the teenager paying particular attention to improving his engine and movement patterns during the pre-season.

“Probably more so building his tank aerobically, and certainly working on his patterns, front and square, he knows if he can bring his pressure that will allow him to attack or defend if he’s in the right position,” Hamill said.

“He had a really good year last year, but once again, it’s only really a start and a taste for him.

“He’s got a lot of drive for a young player. He’s sussed out the system really well at a young age, developed good habits.

“He learnt a lot off Adam Schneider last year; he’s taken over the No. 13 so he’s quite chuffed with that. He’s doing everything right.”
