Source: Manny Ramirez plans workout

Manny Ramirez plans to work out for teams later this month in an effort to return to the major leagues, a source told ESPN The Magazine's Buster Olney.

There was no immediate word on which teams are interested in watching Ramirez work out, Olney reported.

The slugger retired in April after being hit with a 100-game ban for a second violation of baseball's drug policy. He was reinstated from baseball's voluntary retirement list last month, after agreeing to serve a 50-game ban rather than the 100-game ban stipulated for repeat offenders.

His suspension will begin as soon as he signs with any team.

Last month, Ramirez told ESPNdeportes.com tha he made a mistake in using banned performance-enhancing substances and retiring without providing any explanation. He said he is in the best physical shape of the past three years.

"Every day that goes by I regret the decisions I made by following bad advice," Ramirez said. "We are human, we make mistakes, we are not perfect. Everybody deserves a chance to show he has changed."

Ramirez is a lifetime .312 hitter with 555 homers and 1,831 RBIs in 19 seasons with Cleveland, Boston, the Dodgers, the White Sox and Tampa Bay.
