Thanks for the replies. I asked this question because I have an issue with the wording in the rules book. All of these suggested possibilities seem to apply to the wording logically. I'll try to remember that there is a 1.7% chance that the penalty will be to return the runners rather than call the out. As usual - it comes down to my judgment - which is usually horse poo-doo anyway. Of that there is a 99.347 % chance...unless I've been drinking Red Bull.
