Analysis of information sources in references of the Wikipedia article "Pinch runner" in English language version.
A pinch-running appearance only shall not extend the streak.
Comment: This rule is intended to eliminate the practice of so-called courtesy runners.
If an accident to a runner is such as to prevent him from proceeding to a base to which he is entitled, as on a home run hit out of the playing field, or an award of one or more bases, a substitute runner shall be permitted to complete the play.
