Trevor Bauer will NOT face any criminal charges for allegedly punching and choking a woman unconscious during sex, TMZ Sports has learned.

We're also told the decision was made in part because of texts messages between the accuser and Bauer … where she indicated she was looking for rough sex.

Remember, 30-year-old Bauer was accused of getting physical with the woman during two sexual encounters in April and May 2021 … which the alleged victim claimed left her with bumps, bruises, scratches and other injuries.
