ST KILDA'S predicted high turnover of players this off-season has started, delisting three players following exit meetings on Wednesday.
Ruck duo Lewis Pierce and Billy Longer were informed they wouldn't be offered contracts for next year, along with pre-season signing Sam Rowe.

They join experienced midfielder David Armitage in departing the club after the 31-year-old's delisting was announced last week.
David Armitage has played his last game for St Kilda. 
Both Pierce and Longer spent long periods battling concussion this season, while Rowe broke through for his Saints debut and 100th career match in the final round last week.
The removal of both ruckmen opens the door for a pursuit of out-of-contract Port Adelaide big man Paddy Ryder.
"Billy and Lewis were both unfortunately sidelined for most of the year with injury, but we thank them for their commitment to St Kilda over their time at the club," Saints head of football Simon Lethlean said.
"While Sam was only here for one season, he has had a great impact on our group.
"As the club communicated last week, we also thank David Armitage for his incredible service over thirteen years.
"All four men have made important contributions to St Kilda, and we wish them all the best for the future."
Billy Longer has been delisted by the Saints.
It leaves the Saints to make decisions on key defender Nathan Brown, forward Jack Mayo, midfielder Doulton Langlands and defenders Brandon White and Bailey Rice in coming weeks.
Restricted free agent Jack Newnes is exploring options at other clubs despite an offer to remain at Moorabbin.
