Manny Ramirez will not be prosecuted for misdemeanor battery for allegedly slapping his wife Juliana in their Florida home last year ... TMZ has learned.
A rep for the State Attorney's Office tells us ... "The state dropped the charge because the victim was uncooperative. She successfully avoided being served with a state subpoena and is believed to be out of state."
TMZ broke the story ... Manny was arrested on September 12 ... after Juliana called police and claimed Manny had slapped her in the face with an open hand ... causing her to hit her head against the headboard on their bed.
Manny had maintained that he had merely grabbed Juliana by the shoulders during an argument and when he "shrugged her" ... she hit her head against the bed.
