SEB ROSS has joined fellow St Kilda mainstay Jack Billings in rejecting AFL free agency and signing a new deal with the club.

The utility has re-committed for the next two years, in the wake of Billings securing a four-year deal.

Ross, a two-time club best and fairest, was an unrestricted free agent.

He enjoyed another consistent season, finishing seventh in the Trevor Barker Medal count, and the Saints had been confident he would stay.

Ross has finished in the top 10 of the club best and fairest every season since 2016.

Saints list manager James Gallagher also lauded Ross for his off-field influence at the club.

"A lot of Seb's work goes unnoticed externally, but ... we recognise just how important he is to our side on a number of fronts," Gallagher said in a statement.

"Seb is an honest and genuine guy, who has been a very good player for a number of years.

"More recently his versatility and willingness to play multiple roles for the team has become a really important aspect of his football.

"He's played a prominent role in developing the likes of Ryan Byrnes and Jack Bytel during the past few seasons, and we have full faith he'll continue to do that for many other young Saints."
