Thanks

There has to be a play made, a defense attempt to get the BR out at first; for which half of the base to matter.
A live ball appeal for any missed base is by a fielder with the ball touching the base in an appeal manner or tagging the runner.
It can be a dead ball appeal if the runner continues and does not return before action has ended and time called. That would be vocal.
