Does the Run Count?

[BretMan]

(I'll address the ASA rule, not being an NCAA umpire).

When this question came up on another internet forum, some seemed to think that once the third out was recorded (batter-runner going into second base) that the runner who missed the plate could no longer correct his baserunning error.

They were basing this on 5-5-B(2). That rule says that no run shall score when a runner being put out on a tag play is the third out and it occurs prior to the lead runner touching home plate.

Their reasoning didn't seem right to me. Obviously, if there had been no appeal of the missed base, and no retouch, the run would have counted- even though the runner did not "touch" the plate. When the rule refers to "touching" the plate, isn't it really talking about "reaching" or "passing" the plate?

What rule or interpretation supports that a runner may, or may not, correct a baserunning mistake after the third out is recorded?
