"The Oakland Athletics are "very interested" in making Manny Ramirez their designated hitter next season, a source told ESPNDeportesLosAngeles.com.

Ramirez, 39, has been working out in Miami since December and has plans to have open workout sessions for clubs interested in his services at the end of January.

Last week, ESPNDeportesLosAngeles.com reported that the Baltimore Orioles and Toronto Blue Jays had a look at Ramirez batting in an indoor cage.

"The Orioles and Blue Jays saw Manny work and Baltimore liked what it saw, but Oakland has been the team that has expressed the most interest, even before having him work out," the source said."
