Trevor Bauer's assault accuser is firing back at the MLB star after he sued her earlier this year ... filing a countersuit for battery against the Cy Young winner in Los Angeles.
Lindsey Hill, from San Diego, filed a lawsuit for sexual battery and battery in federal court on Tuesday, again alleging 31-year-old Bauer beat her up on two occasions during sex, punching and choking.
Bauer's always adamantly denied the allegations, maintaining he and Lindsey had a consensual, sexual relationship. The L.A. county district attorney's office investigated Hill's claims and opted not to file charges against the Dodgers pitcher.
