"Free-agent Manny Ramirez is trying to decide whether he'll sign with the the A's, Orioles or Blue Jays, a source told ESPNDePortesLosAngeles.com on Friday.

Once Ramirez chooses a team, his agents will then begin contract negotiations with that team.

The A's have been the most vocal among the three teams in their support for adding the 39-year-old Ramirez. Co-owner Lew Wolff, along with assistant general manager David Forst, both said within the past two weeks that the A's are very open to the idea of adding the embattled slugger."
