Rogue Skill mastery in skills with no ranks?

[Particle_Man]

Assuming that the skill can be used untrained, can a rogue pick skills in which she has no ranks for her skill mastery special ability? Because it might be handy to be able to guarantee a DC 10+(dex mod) Balance or Ride check, for instance.

Presumably yes, as there is nothing that says you have to have ranks in the skill for it to be eligible.
