Ruling
1) No, the runner should be called out unless she asked for and was granted time by the umpire.

I assume these are NCAA case plays? Anyway, on the one quoted, I continue to maintain (though I think everyone continues to disagree with me) that the rules do not support an out here (at least the ASA and NFHS rule). The rule does not require the player to maintain contact with the base it simply forbids leaving the base (until the pitch starts at which point they are required to maintain contact). Almost everyone here believes that is a distinction without a difference.
