SEAN Dempster has been nominated for the AFL's Mark of the Year following his spectacular grab late in Sunday's win over Melbourne. 

The veteran defender leapt high over teammate Jimmy Webster to register his second Mark of the Year nomination. 

Coincidentally, Dempster was nominated for the Mark of the Year after St Kilda's last game against Melbourne, in round 11.
