Former World Series Most Valuable Player Manny Ramirez was arrested Monday after a domestic dispute at his South Florida home and charged with battery, police said.

Ramirez, 39, and his wife were arguing in their bedroom when he slapped her face, causing her to hit her head on their bed's headboard, according to a police report. She told the deputy she was afraid the situation would escalate and called police.

Ramirez denied hitting his wife, according to the report, telling a deputy she hit her head after he shrugged her. Ramirez's wife had injuries consistent with her story, but did not want medical treatment.

Ramirez retired in April from the Tampa Bay Rays after he tested positive for a performance-enhancing substance. Rather than face a 100-game suspension for a second violation of Major League Baseball's drug policy, the 12-time All-Star left the game.

Ramirez previously served a 50-game ban in 2009 with the Los Angeles Dodgers. Second-time offenders get double that penalty.

One of the games great sluggers, Ramirez was named MVP of the World Series in 2004 and helped Boston end an 86-year title drought.

He was selected 13th overall by the Cleveland Indians in the 1991 amateur draft and rose quickly through the minor leagues.

He broke into the majors in 1993 and played his first full season the following year, when he finished second to the Royals' Bob Hamlin in voting for Rookie of the Year. Ramirez went on to establish himself as one of the game's most feared hitters, adopting a dreadlock hairdo that seemed to mirror his carefree demeanor.

He signed with the Red Sox as a free agent in December 2000, helping the long-suffering franchise win the World Series a few years later, then doing it again in 2007.

The Red Sox traded him to the Dodgers in July 2008. He instantly became a fan favorite on the West Coast, with "Mannywood" signs popping up around town, as he led Los Angeles to the NL West title and a sweep of the Chicago Cubs in the playoffs. The clutch performances earned Ramirez a $45 million, two-year contract.

All that goodwill fizzled the following May, when Ramirez tested positive for human chorionic gonadotropin, a banned female fertility drug often used to help mask steroid use.

Ramirez played in only five games for the Rays, with one hit in 17 at-bats.
