weird situation

[mcrowder]

Defensive coach might be upset at placing the runner he thought was out back on base. You may have to explain to him that the Verbal "OUT" call followed by the non-verbal safe signal put the runner at jeopardy through no fault of the runner. And you might have to tell him that BY RULE, if an umpire's mistaken call or mishandling of a call places anyone (runners OR defense) at jeopardy, the umpire has a RESPONSIBILITY (not just an option) to fix it.

If he doesn't like that - he can go grumble about it. I believe most coaches, while probably still upset at the call, will see the logic and justice in what you are doing.
