Does This Run Count

[IamMatt]

Since I, like the original poster, am always looking for citations, further clarification can be found in ASA POE 1-K, which is exactly on point.

Tag-Ups. If a runner leaves a base too soon on a caught fly ball and returns in an attempt to retag, this is considered a time play and not a force out. If the appeal is the third out, all runs scored by runners in advance of the appealed runner and scored ahead of the legal appeal would count.

I think NHFS is identical in wording (6-2-h?).
