Not sure why you would ask this. I know (several of) your trainers, and know you have been told:

Never guess an out. If you didn't see an out, it must be safe.

Never guess a catch. If you didn't see a catch, it was no catch.

Never guess a strike. If you didn't see a strike, it must be a ball.

Never guess a swing. If you didn't see a swing, it must not have been one.

Never guess a batter out of the box, never guess an illegal pitch, etc, etc.
