Manny Ramirez recently worked out for the Oakland A's in Florida, sources tell MLB.com's Jane Lee. The A's are reported to have a strong interest in signing the free agent slugger to a one-year deal worth slightly more than the league minimum of $480,000, according to the Associated Press.

If he signs, Ramirez wouldn't be eligible to play for the A's until at least May 30, as he still needs to serve a 50-game suspension for violating the league's substance abuse policy. He tested positive for a banned substance five games into the 2011 season after signing with the Tampa Bay Rays. He opted to retire rather than serve a 100-game suspension, which Major League Baseball eventually reduced by half.

Ramirez, who turns 40 years old in May, hasn't played more than 104 games in a season since 2008. He split the 2010 season between the Los Angeles Dodgers and Chicago White Sox, hitting a combined .298 (.409 OBP, .460 SLG) with nine home runs and 42 RBI in 265 at-bats over 90 games. The A's would most likely use him as a designated hitter. The A's finished 2011 ranked No. 12 in runs scored and home runs out of 14 American League teams.
