How can a batter be called out if the pitcher does nothing?

Answer 1

I'm not a Baseball expert, but I seem to recall a rule against crossing in front of the catcher from one side of the plate to the other when the pitcher is on the mound without first calling time out. Maybe there are some baseball experts out there who can elaborate further. Yes. This is true. If the batter crosses from one side to the other while the pitcher is set to pitch, the batter is declared out. Another way an out can be recorded without the aid of a pitcher is if the batter does anything against the rules like corking the bat.
