[CentOS] rsync doesn't update directory ownership

Hi all,
Has anyone encountered this:
On ServerA, I make this directory:
/var/ftp/pub/userA with ownership root.root

It gets rsynced to serverB with this command:
rsync -avzgorp --delete -e ssh /var/ftp/pub/ root at serverB:/var/ftp/pub/

However, when I change the ownership of /var/ftp/pub/userA to userA.userA, 
this change is not rsync-ed to serverB.

Is there any option to achieve this?
Thank you very much.
