Runner assisted by coach

But, to answer your question (it might matter to someone else) ASA Case Book, 2007
Quote:

PLAY 3.5-8
(FP Only) B1 hits an out of the park home run and, as B1 passes 3B, removes their helmet. The plate umpire calls B1 out.
RULING: When the ball went over the outfield fence, it is no longer a live ball; therefore B1 did not remove their helmet during a live ball and should not be penalized. (3-5E EFFECT)

SO - after five pages - do we all agree that a home run is not a live ball, thus interference for runner assistance during a live ball cannot be called.

Unless appealed by the defense for missing a base, the B/R will score.

BTW - both NFHS and USSSA specifically rule that a "fair fly ball passing over a fence is a dead ball." Maybe ASA could take a hint.
