ST KILDA has locked away one of its most promising young midfielders.

The Saints announced on Tuesday that Seb Ross has re-signed with the club until the end of 2018.

After being drafted with the No.25 pick in 2011, Ross, 23, has become a key part in the Saints midfield group this season, playing all eight games and averaging 26 disposals, five tackles, four marks and four clearances - all career highs.

With 45 games under his belt, the emerging star said it was an exciting time as the club as the Saints look to climb the ladder after several years of struggle.

“The coaching staff have built up over the last two or three years, we’ve got a really exciting young list, we’ve made a fair bit of our games this year, barring the weekend, so it was a pretty easy decision to sign on knowing what’s in front of us,” Ross told the club website.

“I’ve been able to get some continuity in my game this year purely based on the pre-season I had. I didn’t miss too many sessions, I was out there day-in, day-out working with the players and the coaching staff.”

St Kilda chief operating officer Ameet Bains said the club was delighted to lock away another young talent.

“At age 23 and in his fifth season, Seb’s progress in 2016 has been pleasing, especially in his performances against quality opposition,” Bains said.

“Being here until at least 2018 will mean that Seb is able to play a critical part in our push to return to finals.”
