Manny Ramirez has filed for reinstatement from Major League Baseball's retired list and hired new agents, sources said Sunday.

Ramirez faces a 50-game suspension when he returns, rather than 100 games, sources said. Ramirez already served a 50-game suspension in 2009, and he had been notified that he was facing another offense last April when he agreed to step away from baseball.

Second-time offenders get double the 50-game penalty, but the view of baseball officials is that if Ramirez had simply stayed in baseball last April and served his 100-game suspension, then he would've already done his time. In the end -- after Ramirez serves a 50-game suspension, in the event he signs with another team -- he will have wound up serving far more than the 100 games he would've faced.

Teams have been notified of the 50-game ban, sources said. Ramirez's 50-game suspension clock doesn't start ticking until he actually signs with a team.
